Soy Acid is generally suitable within the cosmetic uses reviewed. Its refatting, emollient and emulsifying purposes describe cosmetic effects, separate from a seb derm treatment benefit.

Its checked fatty-acid identity supports a theoretical Malassezia screen, without proving an exact-material feeding effect or a flare from a finished formula. Whole soybean oil, soy proteins and modified soy esters are different materials. No independent human seb derm benefit was established. Consider the complete product and your repeated response, and seek advice about persistent irritation.
