sorbitaani

Sorbitaani is a group of chemical compounds derived from sorbitol and fatty acids. They are a type of non-ionic surfactant, meaning they do not carry an electrical charge. This characteristic makes them useful in a wide variety of applications, particularly in the food and cosmetic industries.

Chemically, sorbitan esters are formed by the esterification of sorbitol with fatty acids. Sorbitol is a sugar alcohol, and the fatty acids can be derived from various sources such as palm oil, soybean oil, or coconut oil. The specific properties of a sorbitan ester depend on the length of the fatty acid chain and the degree of esterification.

In the food industry, sorbitan esters are commonly used as emulsifiers. Emulsifiers help to mix ingredients that normally do not combine, such as oil and water. This is important in products like ice cream, baked goods, and margarine. They can also act as stabilizers and texturizers.

In cosmetics and personal care products, sorbitan esters are found in creams, lotions, makeup, and hair care products. Here, they function as emulsifiers, emollients (softening the skin), and thickeners. Their mild nature and ability to improve product texture make them a popular choice.

Sorbitan esters are generally recognized as safe for consumption by regulatory bodies like the U.S. Food and Drug Administration (FDA). They are often used in combination with other emulsifiers, such as polysorbates, to enhance their effectiveness.
