Gentle Lavender Shampoo Bar (Hand Pressed)

Shampoo bars are so awesome! Not only they are a super-concentrated version of liquid shampoos they also reduce plastic usage, fit in every purse, and usually last way longer than traditional shampoos. I started making shampoo bars about three years ago. And let me tell you, figuring out the right amount of liquid/solid surfactants to create a perfectly lathering, foaming product that holds its shape and lasts long wasn’t easy. It took a lot of time and many trials to get it right. I use it on myself and even my young kids as head-to-toe wash,,,, and they also love it!

Ingredients Overview

  • Sodium cocoyl isethionate –  is a very highly active, finely divided, free-flowing powder (sodium cocoyl isethionate) used in syndet bars, combo bars, liquid soaps, facial cleansers, body washes, and shampoos. It has high foaming power, extreme mildness, and soft and silky skin feel.
  • Sodium Methyl Oleoyl Taurate – a mild, anionic surfactant, Hostapon HTPC gives a high, dense and creamy foam
  • Sodium coco sulfate – is an anionic cosmos certified surfactant that produces a lot of foam and bubbles.
  • Disodium Cocoamphodiacetate is a mild amphoteric surfactant of light color, low viscosity, low irritation, high foamability and high thickening ability. It’s widely used in mild shampoo, body wash, facial cleanser, hand soap, shaving products and so on, as primary or secondary surfactant (source)
  • Cetyl alcohol – Cetyl Alcohol is a fatty alcohol used as an emulsion stabilizer and opacifier, adding body and viscosity to creams and lotions, and improving texture and feel with its characteristic velvety texture.  (source). In shampoo bars it acts as a hardeneer and emmoliant that adds slip to the final product.

  • Broccoli Seed Oil is an amzing oil for skin and haircare. Its sheathing action comparable to silicones brings to the hair softness and shine without weighing them down or smothering them. Its smoothing effect helps control small curls and frizz, and is fabulous for formulating serums for damaged tips.

  • Wheatquat HT (Cocodimonium Hydroxypropyl Hydrolyzed Wheat Protein) – adds highlights to the hair and improves wet and dry combing.

1. Weigh and melt Cetyl Alcohol in a double boiler. (I use these KERN scales and I am super impressed with the quality of this product. Highly recommend it!)
2. Add surfactants.
3. Add the active phase ingredients and mix to combine.
4. Knead the shampoo bar dough until everything is well incorporated.
5. Press your bars using the hand-pressed method or use your favorite molds (silicone, 3D molds, etc.).
6. Place the bars in a freezer for 2-4 hours. Once frozen take them out let air dry for at least 48 hours before packaging.
