Dilauryl Thiodipropionate: Applications in Modified Bitumen and its Preparation Method

Dilauryl Thiodipropionate is a diester of lauryl alcohol and 3, 3'-thiodipropionic acid. It is used as an antioxidant in cosmetic and food products. 

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.

In cosmetics

Dilauryl thiodipropionate also works in cosmetics as a sequestering agent which helps keep ingredients in a formula from having unwanted interactions.  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.
