  • Soap Bar with SCI

    Posted by antmagn on February 1, 2019 at 10:55 am

    Hello, I would like to try making some basic soap with SCI. I hate how lye based soaps feel on skin. I want to make something with neutral ph so it can be used on face too.
    I red that a very basic and mild formula is
    SCI (plain without stearic acid) and
    Cocoamidopropyl betaine
    for surfactants and the rest is ceteayl alcohol and other additives like panthenol, glycerin etc.
    Any help making a basic and mild formula?
    Thank you

    A product you are trying to make is called syndet bar. I noticed an interesting trend, there were 6 or 7 conversations about syndet bars on chemistcorner recently. My advice is to get swiftcraftymonkey’s ezine on shampoo bars. It is the best summary for such products. Don’t add cationic polymers and you will be able to use it on the face.

    In summary you need SCI, CAPB (around 20%) and I would adivice Olefin sulfonate as a second dry surfactant (you can also use SLSa it lathers better but less mild). You want your dry ingredients to be around 70%. This all is very roughly.
