what is sabotaging moisture?

Hello,

I had 20 people use it to test 2 different shower gel formulas.
Formula1:
C12-13 ALKYL LACTAT 0,7
PEG 6 CAPRYLIC CAPRIC TRIGLICERID 0,3
POLYGUERTENIUM-7 %1 USED. (COMPONENTS FOR MOISTURE AND FOAM)
Formula2: 
DEA 2
PEG-7 2
POLYGUERTENIUM- 1 USED.
Formula2 was also found to be more moist. what is the thing that sabotages moisture in the formula?

    You will need to ask again because what you have written makes no sense. For a start, use proper names. POLYGUERTENIUM- 1??? C12-13 ALKYL LACTAT???

  • Hi @Belassi ;

    I tried 2 different formulation. the 1st formulation dried the skin. ı can not understand the reason for this. 

    if we look at the ingredients, the moisture of the formula1 should have been higher. I come to this conclusion when I make a comparison. 


    Formula 1
    C12-13 ALKYL LACTAT      %0,7
    PEG 6 CAPRYLIC CAPRIC TRIGLICERID      %0,3
    POLYGUERTENIUM-7               %1 

    Formula 2
    DEA       %2
    PEG-7    %2
    POLYGUERTENIUM-7   %1

    Can't you use proper chemical names? I cannot make sense of it.

    PEG-7 or PEG-7 something? PEG-7 has no real use in a shower gel, doesn't foam or anything, but might act as moisturiser (obviously only if you don't rinse...).
    DEA is an additive, not a surfactant leaving Polyquaternium-7 as sole cleansing agent in product N°2 = insufficient cleaning = less stripping = higher perceived hydration.
    But that's just a wild guess because your INCI nomenclature does need a serious overhaul...
  • If my guess of your "PEG 6 CAPRYLIC CAPRIC TRIGLICERID" is the same as what i think it is, then based on my experience, it dried my skin slightly. I've not tried the others you have mentioned.
