  • Great body wash becomes dry on skin gradually. Why?

    Posted by dell on February 27, 2021 at 7:35 am

    I have been using my own body wash formulation for over 5 months now on my eczema skin. The first few months it worked wonders as my eczema subsided and healed especially around my fingers. But now on the fifth month, it’s starting to become dry and the skin around my fingers are cracked again. And to add to that, the skin around my legs are becoming dry and flaky. Anyone knows why? Is it because of the continuous use of essential oil?

    The formulation:

    Olive soap
    base 3%

    PS20 1%

    Chamomile Essential Oil
    1%

    Distilled
    Water 42.76%

    EDTA 0.1%

    Sodium Lauryl
    Sulfoacetate 4%

    Coco
    Glucoside 3%

    Sodium Lauroyl
    Sarcosinate 8%

    Acrylates
    Copolymer 2.4%

    Cocamidopropyl Betaine 35%

    Citric Acid 0.34%

    Dmdm Hydantoin 0.4%

    Cocamidopropyl Betaine 35% ? If it is too much you may try 10-20%.

    Atopic dermatitis (eczema) is a condition that makes your skin red and itchy. It’s common in children but can occur at any age. Atopic dermatitis is long lasting (chronic) and tends to flare periodically. It may be accompanied by asthma or hay fever.

    For your formula, i would suggest remove the soap, reduce eo to %0.3, CAPB to %5 and increase the Sulfoacetate to make the total active surfactant around%10. 

    For eczema, i have it too. And there are 3 treatments for it that i know and have used.

    1. Steroids

    2. Suppressor of your immune system
    3. Petrolatum

    The one with least side effect is petrolatum according to my knowledge and experience.
