So True Naturals Soap

soaps22It’s been well-documented on this site how much I love soaps (need proof? Click here, here, or here), so you can imagine how excited I’ve been to put this post up.

I have always been curious about what goes into making these bars of bathing joy. So when wonder-woman and owner of So True Naturals, Mia Rocha-Lauchengco, invited me over to photograph her soap-making process, I jumped at the chance.

So True Naturals makes only 100% olive oil Castile soaps. They are so gentle that they can be used on young and old alike. Each hefty bar smells delicious and lasts for quite a while. Bath time can’t get much creamier than this.

soaps20I asked Mia to share a bit about what makes her soaps different from most while she made a special batch exclusively for some of my lucky readers to try. Please find out how to join at the bottom of the post.

Hi Mia! Can you share with my readers what you you do?

Good question! I think like any other woman, I wear many hats. So first, I am wife to Raymond. Second, I am mother to Natalie (who is five) and David (who is three). Third, I am a soap maker (and everything else it needs me to be) at SoTrue Naturals. Fourth, I am a freelance writer who writes feature articles, PR pieces, and AVP and corporate event scripts. My current, ongoing favorite writing job is writing love letters to my daughter, who has just discovered that writing letters is a lot of fun.



soaps15How did you get into Castile soap making?

I’m an info junkie. When Natalie was born, I had researched every little thing about having a baby. I knew all the websites on breastfeeding, and I could open a pregnancy book on the page with the information I needed on the first try. Much of the stuff I read spoke about the toxic chemicals found in items found in any given person’s home. So I was quite vigilant about that.

Then Nat developed eczema, before she even turned a year old. I could tell it made her uncomfortable, and she was forever scratching. So I did more research. Switched to skin care products that were supposedly mild. Nothing really worked on her, unfortunately.

Then I found out about Castile soap, and that ‘true’ Castile soap is also called the newborn soap because it was mild enough to use on newborn skin. It’s been said it’s the mildest soap there is. So I made a batch for Nat, then another for us, then another for family and friends…

soaps19What exactly makes a true Castile soap? 

A true Castile soap is made purely from olive oil. It got its name because they were first made in the 1500s, in the Castile region of Spain, using olive oil. These days the term ‘Castile soap’ is loosely used to describe soaps made from other vegetable oils, such as coconut oil or palm oil.


100% premium grade olive oil.


A bit of lye (which is fully evaporated once soaps are saponified).

What separates SoTrue Naturals from other soap brands in our local market? 

I make true Castiles, meaning I use only olive oil. I don’t even use pomace, which is solvent-extracted and cheaper. Olive oil makes for a very conditioning soap.

I won’t lie to you, there are many handmade soaps out there, and I’m sure you can pick out any one of them and you will have soap of much better quality than those you buy off a supermarket shelf. But I’ve stuck to the original, centuries-old recipe of a true Castile, because I want to offer a truly luxurious, mild and conditioning soap.

The SoTrue promise is that we would use only ingredients I wouldn’t think twice about using on my own kids. It’s important to me to know where my supplies come from, and who my suppliers are. I could use something labeled ‘essential oil’ and enjoy a better profit margin, but that wouldn’t sit well with me when I have doubts about its quality. In a way, I’m glad my brand is called SoTrue, it forces me to make decisions based on principle and not on cost.

While they’re definitely not the cheapest soaps in the market, I can guarantee that you get what you pay for. I use only quality olive oil and pure essential oils or phthalate-free fragrance oils to scent it.


soaps5Let’s talk fragrance. What types are there? What does phthalate-free mean? 

There’s natural, and there’s synthetic. Natural fragrances are usually essential oils–extracted from plants. Synthetic fragrances are man-made, usually called fragrance oils.

Essential oils are volatile, meaning they evaporate quickly. This is why if you bathe with a soap scented with lavender essential oil, you won’t smell the lavender on your skin after you rinse off. So it’s really more of the experience in the bath. Some essential oils, especially the citrus ones, are VERY volatile…so by the time a soap cures (the time needed to dry up and lower its pH level), the scent is gone!

Fragrance oils are more stable. Unfortunately, fragrance companies do not disclose what’s in their fragrances, and they usually contain phthalates. These are the chemicals that help scents stick to your skin long after you apply them, and studies have shown that phthalates are endocrine disruptors (they affect the way your hormones work in your body, and affect young children–boys, especially–the most). Because of this, fragrance companies have been forced to address the demand for phthalate-free fragrances, and I’ve found some really nice ones for my soap.

The scent from a phthalate-free fragrance oil will not last as long as fragrances that have them, but because they are more stable, their scent will last longer than essential oils would.

soaps5What are some of the other ingredients you mix into your Castile soaps? What are their benefits?

Aside from the olive oil saponified with the use of sodium hydroxide (which is completely used up once the oil is turned into soap), I put in fragrance, this is where essential oils and phthalate-free fragrance oils come in. Essential oils are generally antibacterial and have a lot of benefits, but I like adding them primarily for the scent it imparts. Some soaps have additives such as oatmeal or ground cinnamon. Oatmeal is soothing to the skin, and is a gentle exfoliant. So is ground cinnamon, which also helps promote circulation. I used to think aromatherapy was nonsense, but I have to be honest–whenever I make soaps, I feel really good.

I use iron oxides, too, because they make my soaps look cute (laughs).

A note regarding iron oxides: They are made in a lab. In the 70s, the US FDA banned the mining of iron oxides because of contamination issues (traces of lead, arsenic and other toxic chemicals were usually found in them). So since then, iron oxides have been made in a lab to ensure that all you get are iron oxides are nothing else. It’s the same molecular structure as those found in nature, just made with another method. Iron oxides are the colorants used in mineral makeup.


Adding essential oils for fragrance.


Pouring first layer into molds.

I understand that true Castile soaps don’t lather and have a tendency to get slimy, what’s the best way to use/store them?

Contrary to popular belief, lather has nothing to do with a soap’s ability to cleanse. Soap molecules have two different ends–one is attracted to the oily muck on our skin, and the other end is attracted to water. So when you apply the soap to your skin, one end attaches itself to the grime, and is washed away with water when you rinse.

When you use a true Castile, you get a creamy (okay, maybe slimy), not bubbly, lather. It’s just the inherent property of the soap. The more conditioning it is, the creamier it feels.

Castile soaps are also very high in glycerin, which is what attracts moisture to it. If you leave your soap in a puddle, no matter how small, the soap will absorb it and you will end up with a gooey mess. Same thing will happen if you leave your soap in a part of the shower where water will get to it. So it’s very important to keep it as dry as possible between uses.

Some clients cut the bar in half, then use one half for one shower and another half for the next. I use a really good soap dish that efficiently keeps water away from the soap. It may seem high-maintenance, but I like to think it’s just a matter of taking care of something that takes care of you.

And if you end up with a gooey mess anyway, it’s still good soap! Just think of it as bath gel!

Synthetic iron oxide

Only a pinch of iron oxide is needed for color.


Everything needs to be precise.

Do you recommend using your soaps on just your face or body?

Our soaps are designed for the body, but I do use them on my face. Just remember that the skin on our face is a lot more sensitive than the skin on our body, so be sure to use a moisturizer afterwards. They’re excellent for washing makeup off!


soaps11If someone wanted to try your soaps for the first time, which bars would you recommend? 

Any soap whose scent appeals to you. If you have very, very sensitive skin, I’d recommend the unscented and non-colored ones, like the True Castile or the Oat Castile. If you can’t live without fragrance, but have very sensitive skin, try the Lavender Oatmeal.

What skin types would best benefit from using a true Castile soap?

Because of its mildness and conditioning properties, it’s good for all skin types.


Pouring the second layer.


Soaps are then required to age for at least a month. The longer the better.

Can you share a success story from one of your loyal clients?

Oh, I have quite a few!

I often get mail from moms who tell me that my soap helped soothe their baby’s eczema and what not. Those really make my day. Some of them make me cry! But perhaps the most dramatic story is Kyla’s. She’s 14. We were traveling together early this year and while chatting with her I was looking at her skin, amazed at how smooth it was. It was as smooth as a baby’s bottom, no exaggeration. And I was thinking, wow, for a girl her age it’s unusual that she wasn’t breaking out. Then as if she read my mind, she said, ‘Tita Mia, you know, I really love your soap! I was super breaking out and I tried all sorts of soap and it only cleared up with yours!’ The soap she used was Peppermint Cinnamon.

That made me feel really good, because I know what it’s like to have breakouts at that age. And to make a difference in a young girl’s life in that way? I know it sounds trivial, but really, it isn’t.

  1. Hi there Ms. Cat! I’d love to try this soap because I have never tried using one! The soap I’m using always comes from supermarket shelves! 🙂

  2. thank you for sharing the process!!!!! absolutely FASCINATING!!!!!! – i helped Mia with packaging 🙂

  3. I love Castile soap! I first tried them in the US with the Dr. Bronner brand. Healthy Options carried them for a while but stopped because the supplier couldn’t keep up with the demand. I have since resorted to having relatives bring me huge bottles back from the States. I would love to try a local version and I’m glad one exists!

  4. You know I love soap as much as you 🙂 Would be happy to try! They look so pretty too! It might just help with Natalia’s skin. She’s perpetually scratching and our current oatmeal soap doesn’t seem to be working!

  5. Hi! I have been using So True Naturals’ soaps everyday for 5 months now.

    One of the good things I’ve discovered whenever I’d take care of the Castile Soaps I buy is that they don’t shrink that fast.

    I cut each bar into 20-gram pieces and use only 1 piece at a time per Castile soap (I had 2 bars when I started). Because I keep them dry, even the ones that have been used, each 20-gram block lasts a month for me. I use each piece at least once a day. (NOTE: but I’m quite short. The daily consumption may not necessarily be the same for others).

    Also, since I keep the rest of the pieces in my cabinet, they make my cabinet smell nice.

    P. S.
    If majority of those who will join have not yet tried the soap, no need to count this comment as an entry 😉

  6. You had me at phthalate -free and 100% quality olive oil.. I have skin asthma, my daughter has rough, dry patches on her skin and my infant son has very very sensitive skin. We’ve been on the lookout for soaps that would work for us and I hope this is it. Thanks for the very informative, visual feast post!

  7. My son had atopic dermatitis when he was a baby. He very rarely has flare-ups now, but I still try to be careful. Would love to give this a go! 🙂

  8. I love soaps, esp natural ones. I have a very dry skin so i need a soap to moisturize everyday! Would like to try So True Naturals 🙂

  9. I’m so excited for this soap! I would love to try some – will get mum to bring some over when she comes for Christmas.

  10. I’m so excited to read they will be opening an online store in the US! I’ve had terrible eczema all my life and spend everyday examining my baby’s skin hoping that she hasn’t inherited it (so far so good). I’d love to try this on both of us.

  11. kat atillo-cruz says:

    i’d love to give this a try for my baby who i think has sensitive skin. 🙂

  12. Pia Congmon says:

    Caterina! I would love to try the Peppermint Cinnamon for my son Waki’s breakouts. Will take a ‘before and after’ photo. 🙂

  13. I’m expecting my baby very, very soon — and I think she will love this! Would appreciate a sample. 🙂

  14. I had a severe acne when I was a teenager. Skin solutions helped control it but it’s just so expensive to visit my derma regularly especially when I was still a student. Two years ago, I was diagnosed with urticaria and up to now I still have a vague clue to what was causing the allergies. The skin rashes/itch is just so random and it’s been keeping me from a good sleep most of the time. It’s good to know that there are locally available natural products and I was hoping I can try the soap. Thank you! 🙂

  15. I want to give this as a belated birthday gift for my sister to try because she’s been having acne problems since 14 (and now she’s 27!).

    (I might buy some online for myself as well!)

  16. As a first time mom to a 6 month old son, i’m keen on trying to find products that are not only effective but unquestionably safe. I love how a mom ,with the same outlook, has created a product having her daughter in mind. I would love to try the soap during our bath time bonding moments.

  17. Hi Cat!
    I’m a surfer (as you already know!) and the number one part of the body that is always exposed is the SKIN. We want it to look good and be protected all the time. Not a lot of people know this because it’s not obvious in photos anymore but I used to have something like exzema and my skin was just not even, had a lot of dry parts, suddenly became sensitive to every possible beauty product! It’s gotten better but I’m still searching for soaps that won’t harm my skin and are made of all natural materials. Castile soaps sound really interesting and just might be what my skin needs and I would love to try it.

    Plus I love supporting Filipino products and start up / small businesses and help spread the good word so hopefully I get to try this. Great writing by the way, I loved all the details and the photos as how the soap was made. Will read more of your blog! Thanks for sharing this. 🙂 xoxo

  18. Wow, thank you for sharing the process and educating us about the ingredients in soap making (will watch out for phthalates now 🙂 . I’m in my early 30s who still gets acne and skin asthma on fingers and scalp, and has been thinking of shifting to an all natural beauty regimen, but “all’natural” is hard to come by in Manila. I would love to try this So true naturals soap, it’s my first time to hear of Castile soap, and to think olive oil has been my favorite ingredient in scents, body scrubs and the like.

  19. Because of your reco I have been exploring all kinds of natural soaps. And I have been loving the discovery process. This Castile soap thing intrigues me. Id like to try it, so I hope I am lucky enough to be gifted one, especially since it,s my birthday on September 28! Haha. Great post, cat, and photos, too.

  20. As a surfer, the number one part of my body that is always exposed is my SKIN. It’s not obvious anymore but I used to have uneven skin and a lot of dry spots because of exzema and another condition (I forget the name). It’s made me skin very sensitive to different products and I’m always looking for all natural soaps that I can use. The Castille oil sounds perfect for my skin and I would LOVE to try it and see if it works for me. This might be the soap that I’m looking for!

    Also I love supporting local and Filipino products so I hope I get the chance to try this soap for myself. By the way, great writing and photos, Cat! Thanks for sharing. I’ll read more of your blog! xoxo

  21. These are beautiful! I suffer from psoriasis so I’m forever on the hunt for quality, organic skin care range that is suitable for my skin type. I’ll contact them directly, hopefully they have something for my skin concerns. Once again, thanks Cat! xo

    • I hope they work for you, hon! I know So True Naturals is more than interested to find stockists abroad. Sydney perhaps? 😉

      • Absolutely! Have already started talking to them 🙂 Psoriasis is such a challenging skin condition to have, there may not be any miracle cure but anything that will help the symptoms is great.

  22. If only being chosen weren’t random i’d encourage you to choose joanne..she led me to this site two years ago and it has made my life richer 🙂 jo, u get the soap if my comment makes it! Thank you for this source of goodness Cat!

  23. Mia Villegas says:

    My husband has psoriasis & we tried many brands, name it from expensive ones to cheap. We only settle for a temporary remedy but always on the look out for remedy that will help sooth his condition. I want to give this a try especially now that I have a 7weeks old baby who seems inherited my husband condition because of noticeable breakout. Recently I noticed that it has spread to his entire body & it breaks my heart seeing my very young baby in that condition. Our pedia advised some soaps & moisturizer but it didn’t work so I have stop using them.

  24. tina gabriel says:

    Hi Cat and Mia! I have been wanting to try Mia’s soaps since I started following her on Instagram. I only use Dove as a bath soap because I am sared of what chemically produced soaps can do to my skin asthma, I just found out last year that I am allergic to Lavender. I use olive oil (mixed with sunflower oil and a drop of tea tree oil) for hair treatments and olive oil mixed with brown sugar or coffee ground for body scrub. I would like to try how the Castile soap can make my skin feel. Thank you 🙂

  25. Clarisa J, Jose says:

    how can i buy your products? i luv natural soaps

  26. Kaka Gonzales says:

    After a long and tiring day at work, all I want is a warm and relaxing bath ! These soaps look delicious to use. I have super sensitive skin and I am looking forward to the little wonders Castile soaps will do to me:)

  27. Hi, we have been using natural and handmade soap bars since we found out our eldest daughter has atopic dermatitis. We would like to try So True Castile soap for us to have a first=hand experience on how it is different from other natural brands and if indeed it can quiet down the infamous itch-scratch cycle of patients with skin eczema. Thank you!

  28. Castile soap looks promising! I have developed KP (Keratosis Pilaris) last year and been looking for the perfect remedy for it in months. I’d be very happy to try SoTrue and witness its wonders. 🙂

  29. I’m having such a great morning reading your comments!

    As much as I wish I could say that our soaps are a cure for certain skin conditions, I can’t. They’re soap (ok, I’ll say they’re darn good ones!) and at best may help soothe the symptoms. Everything else is a bonus 🙂

    So here’s hoping we get a lot of bonuses using SoTrue Castile soaps! 🙂

    Have a great week.

  30. Mia, if I get chosen randomly, I’ll pass, because I am already a permanent user. You can choose another in place of me.

    I just want to give a tip to the new users and also to your loyal users. One tip I would like to share is how I keep your Castile soap dry. I use a sponge as my soap dish. It keeps it totally dry. I have two sponges. When I have to wash one, I use the other.

  31. I have a sister who would benefit from this soap. She developed eczema when she was young. Although it is dry now, it still bothers her sometimes.

  32. I have a tendency to have skin eczema. I had one before. I have a very thin skin. Much like an onion peel. But what I’m thankful for that is I’m not a keloid former even though I got bruised a lot. So i tend to be very picky with the kind of soaps I use. I don’t use the commercial brands as it tends to dry my skin. I want to try this Castile soap since I’m a great fan of olive oil and other natural based ingredients. I would really be grateful if I will be chosen as this is an opportunity to try a great product.

  33. Where do you get the molds that you used in these pictures? I have been making my own soap for about 10 years now. I have wooden molds but they can be tedious to work with and these ones look great.

  34. Oh, sounds promising! I’m a newbie mom who’s always in the lookout for all things safe and natural for my baby. 🙂 Gusto ko sanang i-try to for baby and me. Paranoid na rin ako ever since I’ve read ’bout phthalates, parabens, etc kaya as long as may mahanap na natural/organic products, I choose those. 🙂

  35. I love these soaps! I’ve been using it for almost 2 years now. I would want to get some more not for me to try, but for my friends and relatives with children. When I do have kids, this is definitely what they’ll use.

    I also keep the soaps in my cabinet (as indicated in one of the earlier comments)- best way to keep them solid and to also get fragrant clothes 🙂

    Thanks for this post: both pictures and the article are both wonderful to see/read.
