  • Review my handwash formula

    Posted by drjaysee on May 20, 2022 at 6:30 am

    I have made  a handwash in better way after some failure at some different steps.
    The ingredients are:
    Water 250ml
    Sles 100ml
    Glycerin 2ml
    CAPB 20ML
    AOS 10 ML
    CDEA 10ML
    SALT 10MG
    Fragrance oil
    Colour 

    Result product  was good, viscosity, foaming, moisture everything is good. 
    I want to know your views upon it.
    ,please tell me what is lacking? 
    Preservative? Why we need to preservative because these all are chemicals,? If we need then,  Is phenoxyethanol at 1%  good?
    Do we need to CMEA for getting viscosity rather then NaCl? As previous attempts the viscosity reduced after adding fragrance oil and colour, why?
    Need your suggestions 🙏

    Preservative? 

    Hi! Yes, you should have a broad-spectrum preservative in products which contain (or will be interacting with) water, because water is a source of life and a good ground for bacteria and mold.

    Why we need to preservative because these all are chemicals?

    Even more - everything in our life is chemicals. Why? Because bacteria and mold are so stubborn, so they can live and growth in almost any cosmetic product.

    Is phenoxyethanol at 1%  good?

    Again, I am not a chemist, but I think just phenoxyethanol is not enough, since most of commercial products tend to not use it solely. Also, preservative choice depends on many factors - how long shelf life should be? should it be “organic” or “natural”? What is pH of your product? etc.

    Informative!  Thanks. 
    I want to know some broad spectrum preservative that can be used in any wash and cosmetic products.
    I think you are saying a kind if combo of different preservative of particular purpose. 
    If anyone can share your knowledge, please..

    Suggest one of Abdullah’s suggestions with EDTA and benzoate.
