SORBETH-30 TETRAOLEATE

CAS Number	63089-86-1
Chem/IUPAC Name:	(Z)-octadec-9-enoic acid;2-[2,3,4,5,6-pentakis(2-hydroxyethoxy)hexoxy]ethanol
EINECS/ELINCS No:	684-590-0
COSING REF No:	58325

Sorbeth-30 Tetraoleate is a tetraester from oleic acid and polyethylene glycol ether of sorbitol. It is a good emulsifier and solubilizer for a wide range of substances. It can be used to create cleansing oils that emulsify when they come into contact with water, making them simple to rinse off and leaving no greasy residues. It is very good at removing makeup that has become trapped into the skin. It belongs to a class of compounds called polyethoxylated sorbitan or sorbitol esters of fatty acids, or polysorbates.

What is SORBETH-30 TETRAOLEATE used for?

Sorbeth-30 tetraoleate is a water-loving substance that functions as a self-emulsifying surfactant. It is widely used in oil cleansers because it enables the interaction of the oils with water for simple rinsability. It is suitable for non-polar oils like liquid paraffin, etc. The recommended concentration for oil-based cleaners is 10-15%.

It helps to form emulsions by reducing the surface tension of the substances to be emulsified and they help other ingredients to dissolve in a solvent in which they would not normally dissolve. The PEGs Sorbitan/Sorbitol Fatty Acid Esters also clean the skin and hair by helping water to mix with oil and dirt so that they can be rinsed away.

Origin

Typically, sorbitol is esterified with fatty acids or their anhydrides at temperatures between 130-180 °C, usually under acid catalysis. Sorbitol loses water at the temperature needed for esterification, resulting in three different isomers of sorbitan and (after losing another water molecule) isosorbide. These dehydration products form corresponding sorbitan esters when they interact with a fatty acid. These substances, also referred to as "spans," undergo ethoxylation to create polysorbates. In a different typical manufacturing process, ethylene oxide and a basic catalyst react with sorbitol at a temperature between 200 and 250°C. Sorbitol is isomerized in this situation as described above. Ethoxylated products, also known as carbowaxes, are produced when ethylene oxide is added. These products are then esterified with fatty acids to create oligomers of polyoxyethylene sorbitan esters (aka polysorbates).

Safety profile

The Cosmetic Ingredient Review (CIR) Expert Panel has evaluated the PEG Sorbitan/Sorbitol Fatty Acid Esters' safety. The Sorbeth-30 Tetraoleate and other PEG Sorbitan/Sorbitol Fatty Acid Esters are safe for use as cosmetic ingredients, according to the CIR Expert Panel's analysis of the scientific data. Most of the safety test data that is currently available relates to polysorbates or their constituent sorbitan fatty acids, polyethylene glycols, and fatty acids, all of which have successfully passed safety evaluations.
