Octyldodecanol (CAS 5333-42-6) is a clear, odorless, long-chain branched fatty alcohol produced via the Guerbet reaction, primarily utilized as a hydrolysis-stable emollient and solvent in the manufacturing of color cosmetics and skin care emulsions. This 2-Octyldodecan-1-ol compound functions as a superior pigment dispersant and coupling agent in Isoarachidyl alcohol based formulations, ensuring the uniform distribution of colorants in lipsticks and foundations while providing a medium spreading profile without the greasy feel associated with linear alcohols. To support industrial-scale requirements, we provide bulk supply with competitive factory pricing and ensure rigorous quality control through customized specifications alongside standard technical documentation, including MSDS, TDS, COA.

FAQ - Technical & Supply Chain
-
Q:
Is Octyldodecanol (CAS 5333-42-6) susceptible to oxidation or hydrolysis?
A: No, due to its saturated branched structure (C20H42O), this alcohol is chemically inert and highly stable against hydrolysis and oxidation across a wide pH range, making it ideal for formulations containing active ingredients like salicylic acid or aluminum salts. -
Q:
What is the specific advantage of using this branched alcohol in color cosmetics?
A: It acts as a highly effective solvent for waxes and pigments, preventing crystallization (blooming) in stick products like lipsticks and concealers, thereby maintaining structural integrity and color pay-off over time.
