Frequently Asked Questions

What is cetearyl octanoate?

Cetearyl octanoate is a fatty-alcohol wax ester used as an emollient and skin-feel/texture modifier in cosmetic and personal-care formulations. It adds cushion and body to creams, sticks, and anhydrous bases. RawSource supplies it in bulk for formulators and contract manufacturers.

Is cetyl ethylhexanoate the same as cetyl alcohol?

No. They are different chemistries: cetyl/cetearyl alcohol is a fatty alcohol, while cetearyl octanoate and cetyl ethylhexanoate are wax esters (an alcohol reacted with a fatty acid). They are distinct INCI materials with different roles in a formulation.

What is cetearyl octanoate made from?

It is a wax ester formed from a long-chain fatty alcohol and a fatty acid (C38H74O2 class). Esters of this type are produced synthetically and used for their emollient, skin-feel, and texturizing properties in anhydrous and emulsified systems.

What is the CAS number for cetearyl octanoate?

The CAS associated with this material is 22393-88-0, and the molecular formula is C38H74O2 (a C38 wax ester). Always confirm the exact grade and identity against the CoA and SDS for your specific lot. RawSource provides both with each shipment.

What is the cost of bulk cetearyl octanoate?

Bulk pricing depends on volume, packaging (drums, totes, IBCs), and grade. RawSource quotes per current contract terms rather than a fixed list price. Submit a bulk RFQ with your target volume and packaging for a current quote.
