Solid Stick Soap

Does anyone have any experience formulated solid state stick soaps? 'soap' may not be the correct term as it wont be made like a normal soap but consist mainly of melting surfactants and trying to thicken them... so planning to use
Sodium Lauryl Sulfate - needles
Sodium Lauroyl Sulfosuccinate
Sodium Lauroyl Sarcosinate
Cetearyl Alcohol
A small amount of oils and fragrance

Any tips? 


  • You might need to add a filler to control the thickness and reduce the cost. I would suggest using starch. Some oils, or petrolatum can add a nice feel. Avoid low MW silicones if possible.

    sodium stearate is your best bet for creating water-based sticks

    Maybe look for solid shampoo formulas for ideas. Have you also considered Sodium Cocoyl Isethionate (SCI) and Sodium Lauryl Sulfoacetate (SLSA) as surfactants. I would also recommend adding some amphoteric surfactants to improve mildness.
