I want to share my go-to shampoo bar formula which can be tweaked to suit any hair type.
I love this formula! It makes a very hard, long-lasting shampoo bar, which produces a crazy amount of thick, dense foam and fluffy bubbles.
Glycerine (mix with Euxyl PE9010)
|0,6||0,30%||50% Citric Acid Solution|
|4||2,00%||Fragrance Oil or Essential Oil Blend|
|2||1,00%||Preservative Euxyl PE9010 or Optiphen Plus|
Optiphen Plus is a pH-sensitive preservative as it works best at a pH lower than 6 so make sure you check the pH level of your end product and adjust accordingly. Aim for 5-5.5 if you use Optiphen Plus.
- Mix your dry ingredients.
2. Mix you liquid ingredients.
3. Add colorant (I used mica) and knead like a dough until your shampoo bar ingredients are well combined.
3. You can press your bars with a pneumatic or electric press, manual press, 3D shampoo bar mold, mooncake press mold, plastic mold, and even silicone soap mold. I used a 100g mooncake press mold. Make sure you pack your molds super well so your bars last longer and hold their shape well.
SCI Noodles – Sodium Cocoyl Isethionate is a gentle surfactant derived from coconut oil. It’s a very mild surfactant with thick, lathery foam.
SCS Powder – Sodium Coco-Sulfate is an excellent coconut-derived surfactant. It’s NOT the same as Sodium Lauryl Sulfate. SCS is gentler and it has a pH of 7.5–10.5 depending on the batch and your supplier.
Cocamidopropyl Betaine – is a very mild amphoteric surfactant with a pH of 5-6.
Sodium Lactate – an excellent humectant and pH adjuster in skincare and haircare products.
Glycerine – is a humectant that draws the moisture from the air into our skin and hair. I only added it to the formula because I am using Euxyl PE9010 as my preservative and it has a limited water solubility so it’s recommended to mix it with glycerine, propanediol 1.3, propylene glycol.
50% Citric Acid Solution – is used to lower the pH of our shampoo bar. Mix 50g of citric acid+50g of distilled water and there you go, you just made your very own 50% Citric Acid Solution. Store in fridge and use for adjusting the pH of your creams, lotions, shampoos, serums, conditioners.
Fragrance oil or Essential oils – make our product smell nice. I used a combo of Rosemary, Lemongrass, Tea Tree essential oils.
Euxyl PE9010 – is a broad spectrum preservative, which means it is effective against bacteria, mold, and yeast.
- You can use SLSA instead of SCS. You’re going to get a gentler bar if you go with SLSA.
- You don’t have to color your shampoo bars and you can use water-soluble dyes to color your bars.
- Coco-Glucoside or Decyl Glucoside can be used instead of Cocamidopropyl Betaine. They’re not the same ingredients, they all have different pH levels so make sure to check the pH of your endproduct and adjust accordingly.
