  • Is high CAPB making no-sulfate handwash sticky?

    I tried this formulation in a foamer bottle

    water qs to 100%
    EDTA Na-4 0.1%
    Dehyton-K 20% (6% active CAPB)
    generic decyl glucoside 10.4% on an active basis
    citric acid qs for pH to 5
    methylparaben 0.3%
    propylparaben 0.09%
    water soluble fragance

    and it leaves a slightly sticky afterfeel
    I previously tried an almost identical formulation, only that active CAPB is 3% and it feels fine, no stickiness and it rinses off faster.

    Is CAPB making it feel sticky?

    @Gunther, I dont think so. I am making a similar product. Total active surfactants 10%, out of which 80% is CAPB. Remaining is coco glucoside and decyl glucoside. Also in a foaming bottle, and preserved with parabens. Maybe you are using too much of decyl glucoside?

    Is that 8% active CAPB
    and 2% active glucosides
    I mean are the % stated meant for active ingredient ?

    @Gunther I think in total 30.4% active is too much for a hand wash

    @Gunther, I checked my formula, 70% of CAPB not 80%, which is 7% of the formula. It is not sticky at all. It’s tear-free gentle facewash with total concentration of surfactants of 10%. I think you might have too much of decyl glucoside.

    INCI % %WW of surfactants Actual concentration
    Aqua 62.9%    
    Tetrasodium
    EDTA
    0.1%    
    Glycerin 10.0%    
    Cocamidopropyl
    Betaine
    20.0% 35.0% 7.0%
    Decyl
    Glucoside
    2.0% 63.0% 1.3%
    Coco Glucoside 4.0% 50.0% 2.0%
    Paraben DU 1.0%    
    Citric Acid QS
