Composition and Description

LANOWAX COSMETIC GRADE is a cheaper alternative to LANOWAX EP. It consists of the highly refined, unsaponifiable fraction of wool wax, which is additionally subjected to molecular distillation to improve both colour and odour. Synonyms: wool wax alcohols, lanolin alcohols, wool alcohols. LANOWAX COSMETIC GRADE is a very complex mixture of alcohols with a mean molecular weight of about 370 Da, consisting of cholesterol, lanosterol, agnosterol, and their dihydro derivatives as well as straight and branched chain aliphatic alcohols.

Features

The cholesterol content in LANOWAX COSMETIC GRADE is lower than in the pharmaceutical quality LANOWAX EP, because it is molecularly distilled from a wool alcohol grade, from which a major part of the cholesterol was extracted (for making NK cholesterol). This is also the reason why this grade can be offered at a lower price. Despite the reduced cholesterol content, the emulsifying properties are in no way less than that of the pharmacopoeial quality. Since it is manufactured gently in modern facilities, the initial peroxide value (measure of oxidation) is very low. Therefore LANOWAX COSMETIC GRADE does not need additional stabilisers. Nevertheless, a shelf life of 2 years is guaranteed. Upon request, BHT or natural alpha-tocopherol can be added as stabilisers.

Applications

LANOWAX COSMETIC GRADE can be used for the same application as LANOWAX EP. Its emulsifying properties can be increased by the addition of cetyl alcohol, beeswax or lanolin (de-oiled). These mixtures are the basis of ointments with an remarkably good colour characteristic. LANOWAX COSMETIC GRADE can be used in small quantities as a thickening agent in shampoos and bath gels.

Dermatology

LANOWAX COSMETIC GRADE consists of Wool Alcohols, a substance that is used in many pharmaceutical and cosmetic products. In only very few cases an allergic reaction was observed. The substance is also listed in pharmacopoeias such as in the Ph. Eur. and USP. Wool Alcohols showed an LD50 in acute oral toxicity test greater than the maximum administered dose, reflecting an extremely low toxicity.

Processing

LANOWAX COSMETIC GRADE is easy to use. It is safe, melts easily and has a relatively low volatility. Prolonged heating above the melting point should be avoided. In cases where cholesterol crystals are still present after melting, the melt can be further heated to 115 °C. Subsequently, it should be quickly cooled down. LANOWAX COSMETIC GRADE should be stored cool and dry in well-sealed containers in preferably large pieces with minimal surface area.
