Chemical Properties
white to almost white crystalline powder
Uses
It is used as emollients, masking agents and skin conditioning and a glosser and thickener for creams. It improves emulsion texture and stability and gives structure to cosmetic sticks. Used in skin and hair applications.
Uses
The chemical structure of cetyl palmitate (synthetic spermaceti) is the same as whale spermaceti. It may be used to thicken, produce viscose emulsions, give stability, and add texture to emulsions. It is similar to cetearyl palmitate.
Uses
Palmityl Palmitate is a wax ester of palmitic acid used in cosmetic and personal care products.
Definition
ChEBI: A palmitate ester resulting from the formal condensation of palmitic acid with palmityl alcohol. It is used as a thickener and emollient in cosmetics.
General Description
Cetyl Palmitate is an ester of palmitic acid, obtained via the reaction of cetyl alcohol and palmitic acid. It is an ingredient of many cosmetic preparations.
Pharmaceutical secondary standards for application in quality control, provide pharma laboratories and manufacturers with a convenient and cost-effective alternative to the preparation of in-house working standards.

Synthesis
GENERAL METHOD: 1.0 g (7.69 mmol) of 1-hexadecanol was added to a 50 mL round-bottomed flask, followed by 0.523 g (0.66 eq.) of NaBr and 0.383 g (0.33 eq.) of NaBrO3, and 10 mL of H2O [this aqueous solution has a molar ratio of bromide to bromate of 2:1]. The reaction mixture was stirred vigorously to ensure complete dissolution of the contents. An aqueous solution of H2SO4 (0.5 equiv, prepared from 0.21 mL of 98% H2SO4 with 1 mL of water) was slowly added to the above reaction mixture at room temperature with continuous stirring for 2.5 hours. The reaction mixture was continued to be stirred for up to 24 hours. Upon completion of the reaction, the product was extracted with CH2Cl2 (3 x 15 mL) and the organic layer was dried with Na2SO4, followed by removal of the solvent to afford hexadecanoic acid hexadecyl ester in 98% yield (0.953 g) as a colorless liquid. The structure of the product was confirmed by GC-MS and NMR.
