  • Where’s the good scent come from?

    It’s fragrance free, but has a light (extremely light) good scent that reminds me apples:

    Aqua (water). Glycerin. Isodecyl neopentanoate. Cyclopentasiloxane. Nylon-12. Cyclohexasiloxane. Cetyl alcohol. Dimethicone. Polyacrylamide. Ammonium acryloyldimethyltaurate/VP copolymer. Ethylhexylglycerin. PPG-15 stearyl ether. C13-14 isoparaffin. 1,2-hexanediol. Caprylyl glycol. Acrylates/C10-30 alkyl acrylate crosspolymer. Dimethiconol. Laureth-7. Sodium hyaluronate. BHT. Biosaccharide gum-2. Disodium EDTA. Sodium hydroxide.

    I would say it is from the caprylyl glycol, aka 1,2-octanediol, which is part of the aroma profile of some fruits

    Continuing with Ruben’s observation I would like to add that many esters also have typical fruity smells.

    I think the caprylyl glycol and ethylhexylglycerin are the likely items, I suspect that this is the preservative, something similar to Spectrastat or Spectraguard, used at about 0.7% typically. This is an anti-wrinkle preparation? I make an enzymatic exfoliant gel using Spectrastat as the preservative and even with no fragrance it has a pleasant mild aroma.

    in my experience, preservative-grade caprylyl glycol and ethylhexylglycerin are virtually odourless, so I doubt it’s either of them

    I’d guess it’s either isodecyl neopentanoate (an ester which is relatively volatile compared to the other ingredients, and thus, further to @milliachemist’s point, the most likely thing to smell like fruit), or something they’ve not declared on the label

    I doubt that too, plus caprylyl glycol is an alcohol not an ester.

    In this case I would say, from all ingredients, Biosacharide gum-2 could have some odor, as it is a rhamnose derivative. It would account for a very light sweet fruity odor. From what I see it could be part of Rhamnosoft and I haven’t smelled that one yet.
