Composition and Description

LANOLIN FATTY ACIDS (Bleached) are produced from the hydrolysis of lanolin, a natural, renewable raw material, which is obtained from the scouring (washing) of raw wool. It is a highly complex mixture of fatty acids, composed of roughly 40% by weight of straight-chain acids, 20% of branched-chain acids and approximately 40% of hydroxy acids. The majority of this mixture of fatty acids is saturated with carbon chain lengths of between C8 and C40.

Features

LANOLIN FATTY ACIDS (Bleached) are a by-product of the manufacture of lanolin alcohol; this is therefore very cost-efficient. It is a unique product with the consistency of a soft wax, and has yellow-to-cream colour. Its soaps have o/w emulsifying properties, and in emulsions the imperfect solubility of soaps does not present a problem.

Applications

LANOLIN FATTY ACIDS (Bleached) are mostly used in technical applications, such as anti-corrosives, lubricants, liquid and semi-solid polishes and textile additives. They are not generally used in their natural form in cosmetic products, but rather as a neutralized soap in applications such as o/w creams and shaving soaps. LANOLIN FATTY ACIDS (Bleached) give a smooth texture to creams and appear to have a mild emollient function. This product also makes a useful feedstock for lanolin esters such as Isopropyl Lanolate, Glyceryl Lanolate and Methyl Lanolate.

Dermatology

LANOLIN FATTY ACIDS (Bleached), used in the form of soaps, has elicited no reports of adverse reactions in over 50 years of use, and is generally recognized as non-toxic and safe. It is, however, not recommended to apply the free acids themselves in their 100% form to the skin.

Processing

LANOLIN FATTY ACIDS (Bleached) are relatively easy to melt, and are highly compatible with other fatty acids oils, fats and waxes. This product should not be held at a high temperature for long periods, otherwise the acid value may fall significantly as a result of lactone formation. Storage should be in closed containers in a cool place.

Solubility at room temperature

Water: insoluble; mineral oil: partially soluble; acetone: partially soluble; ethanol: partially soluble; isopropyl myristate: partially soluble.
