Dilauryl Thiodipropionate - 123-28-4

Key Functions: Cosmetics & Personal Care, Food Contact & Additives, Industrial / Manufacturing, Plasticizers & Polymer

Dilauryl thiodipropionate (DLTDP) (IUPAC name: dodecyl 3-(3-dodecoxy-3-oxopropyl) sulfanylpropanoate) is the diester of lauryl alcohol and 3,3’-thiodipropionic acid, and it is part of the ester and thio compound chemical classes. Its primary use is as an antioxidant in cosmetics and food additives (PubChem 2021), a sequestering agent in cosmetic formulations (CIR 1992, 2010), an additive for lubricants and greases, and plasticizer and softening agent (HSDB 2012, CIR 2010). Dilauryl thiodipropionate is manufactured by esterification reaction between thiodipropionitrile and lauryl alcohol using acid catalysts hydrochloric acid and sulfuric acid under vacuum. The reaction is conducted under vacuum to remove water, driving the reaction to completion. Once the reaction is complete, the products are filtered to remove impurities, and molten dilauryl thiodipropionate is converted to solid products by flaking.
