Frequently Asked Questions
What is pentaerythrityl tetracaprylate/tetracaprate used for?
Pentaerythrityl tetracaprylate/tetracaprate (CAS 68441-68-9) is the pentaerythritol tetraester of caprylic (C8) and capric (C10) acids, supplied as a light emollient ester. It is used as an emollient, a low-viscosity spreading agent and carrier for actives and pigments, and a lubricating ester base in personal-care formulations.
What is pentaerythrityl tetracaprylate made from?
It is produced by esterifying pentaerythritol with a blend of caprylic (C8) and capric (C10) fatty acids, yielding a tetraester mixture. These medium-chain acids give the ester its light, low-viscosity character.
What industries use pentaerythritol esters?
Pentaerythritol esters are used across cosmetics and personal care (as emollients and pigment carriers), synthetic lubricants (as ester base stocks), and coatings/resins. This particular C8/C10 tetraester is positioned mainly for skin-care and personal-care formulating as a light emollient.
What is the CAS number for pentaerythrityl tetracaprylate/tetracaprate?
It is supplied under CAS 68441-68-9, a UVCB covering pentaerythrityl esters of mixed C8/C10 acids, so it carries no single molecular formula. An HS code is not listed on the standalone record; confirm the appropriate tariff line for fatty-acid esters with your customs broker.
How is bulk pentaerythrityl tetracaprylate supplied, and how do I get a price?
RawSource supplies this emollient ester in bulk industrial packaging such as drums and IBCs/totes for manufacturers. Pricing is volume-based; request a bulk quote with quantity and ship-to and we will include current CoA and SDS.
What is the REACH and TSCA regulatory status of Pentaerythrityl Tetracaprylate/Tetracaprate?
Pentaerythrityl Tetracaprylate/Tetracaprate (CAS 68441-68-9) is subject to U.S. TSCA Inventory requirements; supplying it into the EU requires valid REACH registration ((EC) No 1907/2006). RawSource cannot verify a third-party supplier's registrations — buyers should require documented TSCA and REACH compliance for their jurisdiction and volume (EC 270-472-2).
