    Hi 
    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
    Glycerin
    A small amount of oils and fragrance

    Any tips? 
    Thanks

    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.
