Neopentyl glycol diheptanoate

Neopentyl glycol diheptanoate (CAS 68855-18-5, EC 272-469-1) is a diester of neopentyl glycol and heptanoic acid, commercially available under the trade name Truprotect Sun. It carries no assigned E-code and belongs to the oils, fats, and waxes chemical category.

In personal care formulations, it functions as an emollient carrier and solvent for UV filters, improving their skin spreadability and compatibility within sunscreen systems. In lubricant and metalworking applications, its ester structure provides film-forming lubricity and acts as a plasticizing component in synthetic base fluid blends.

Neopentyl glycol diheptanoate is subject to REACH registration requirements for supply within the European Economic Area. Procurement teams should confirm supplier documentation including Safety Data Sheets and certificates of analysis. Packaging formats and available grades vary by supplier and should be verified at the point of enquiry.
