Cetostearyl alcohol, cetearyl alcohol or cetylstearyl alcohol is a mixture of fatty alcohols, consisting predominantly of cetyl (16 C) and stearyl alcohols (18 C) and is classified as a fatty alcohol. It is used as an emulsion stabilizer, opacifying agent, and foam boosting surfactant, as well as an aqueous and nonaqueous viscosity-increasing agent. It imparts an emollient feel to the skin and can be used in water-in-oil emulsions, oil-in-water emulsions, and anhydrous formulations. It is commonly used in hair conditioners and other hair products. It has melting point of about 48C to 56C.

Specifications of Cetostearyl Alcohol USP NF Grade:
Cetylstearyl alcohol --- CAS 67762-27-0.

DEFINITION
Cetostearyl Alcohol contains NLT 40.0% of stearyl alcohol (C18H38O), and the sum of the stearyl alcohol content and the cetyl alcohol (C16H34O) content is NLT 90.0% and NMT 102.0%. It is obtained from sources of vegetable, animal, or synthetic origin.

Specifications of Cetostearyl Alcohol BP Ph Eur Grade:
Action and use: Excipient.

DEFINITION
Mixture of solid aliphatic alcohols, mainly octadecan-1-ol (stearyl alcohol; C18H38O; Mw 270.5) and hexadecan-1-ol (cetyl alcohol; C16H34O; Mw 242.4), of animal or vegetable origin.
Content:
— stearyl alcohol: minimum 40.0 per cent,
— sum of the contents of stearyl alcohol and cetyl alcohol: minimum 90.0 per cent.

CHARACTERS
Appearance: White or pale yellow, wax-like mass, plates, flakes or granules.
Solubility: Practically insoluble in water, soluble in ethanol (96 per cent) and in light petroleum. When melted, it is miscible with fatty oils, with liquid paraffin and with melted wool fat.

IDENTIFICATION
Examine the chromatograms obtained in the assay.
Results: The 2 principal peaks in the chromatogram obtained with the test solution are similar in retention time to the principal peaks in the chromatogram obtained with the reference solution.

TESTS
Appearance of solution: The solution is clear and not more intensely coloured than reference solution.
Dissolve 0.50 g in 20 mL of boiling ethanol (96 per cent). Allow to cool.
Melting point: 49C to 56C.
Acid value: Maximum 1.0.
Hydroxyl value: 208 to 228.
Iodine value: Maximum 2.0.
Dissolve 2.00 g in methylene chloride and dilute to 25 mL with the same solvent.
Saponification value: Maximum 2.0.
