Dilauryl Thiodipropionate  description

Dilauryl thiodipropionate is a part synthetic, part plant-derived ester blend made from the fatty alcohol lauryl alcohol and the antioxidant thiodipropionic acid. Not surprisingly, it has antioxidant benefits on skin and, according to older research from Avon, may play a role in fading the appearance of discolorations.It also works in cosmetics as a sequestering agent which helps keep ingredients in a formula from having unwanted interactions. As such, it also helps stabilize cosmetics.This ingredient’s safety has been reviewed and deemed safe as used in cosmetics. Usage levels of dilauryl thiodipropionate are 1% or less, with low amounts in the range of 0.05% being standard since this amount is considered non-irritating and non-sensitizing to skin.
