Frequently Asked Questions

What is isocetyl stearate used for?

Isocetyl stearate (CAS 95912-86-0, C42H84O4) is the isocetyl alcohol ester of stearic acid. It is used in cosmetic and personal-care formulations as an emollient, a skin-conditioning oil-phase ester, and a spreading/carrier agent in creams and lotions.

Is isocetyl stearate the same as isopropyl isostearate?

No. Isocetyl stearate is the isocetyl-alcohol ester of stearic acid, while isopropyl isostearate is a different ester (isopropyl alcohol with isostearic acid). They have distinct CAS numbers and properties; specify the exact INCI name when ordering.

What is the chemical identity of isocetyl stearate?

It is the branched C16 (isocetyl) alcohol ester of stearic acid, CAS 95912-86-0, with molecular formula C42H84O4. These identifiers appear on the CoA for specification matching.

What HS code applies to isocetyl stearate?

As a stearic-acid ester it is classified under HS 2915.70 (palmitic acid, stearic acid, their salts and esters). Confirm the destination-country tariff line with your broker.

Is isocetyl stearate available in bulk?
