Stearyl heptanoate

Stearyl heptanoate (CAS 66009-41-4), also known as octadecyl heptanoate, is a synthetic ester of stearyl alcohol and heptanoic acid used across personal care and industrial formulations.

It functions primarily as an emollient, lubricant, and skin-conditioning agent, delivering a lightweight, non-greasy feel in finished products. In cosmetics and personal care, it is used in skin creams and lotions.

Lip products and color cosmetics utilize this ester to improve spreadability and provide a smooth after-feel without heavy occlusion. Sunscreen and foundation formulations incorporate it to enhance pigment dispersion.

This ingredient helps optimize texture on the skin for various beauty applications. In lubricant and metalworking applications, it contributes to boundary lubrication in light-duty formulations where ester-based fluids are preferred.

Coatings and sealant formulators use it as a plasticizing or slip-modifying additive to adjust surface properties and film flexibility. Stearyl heptanoate is typically supplied as a pale yellow to white waxy solid.

It may also appear as a low-viscosity liquid depending on temperature. It is available in cosmetic-grade quality, with purity specifications commonly aligned to industry standards for ester-based emollients.

Packaging is generally offered in drums or intermediate bulk containers suited to industrial and cosmetic manufacturing volumes. This versatile chemical ensures consistent performance across diverse manufacturing sectors.
