Microcrystalline waxes (also termed microwaxes) are made up out of neutral non-polar long-chain hydrocarbon chains with relatively high melting points, from 70°C.
Due to their ramate structure, these waxes form exceedingly fine crystals. This leads to special properties such as the retention of oil and solvents.
They vary from pure microcrystalline waxes to high-tech wax blends to which specific additives are added, varying in physical properties, such as hardness, viscosity and melting point.
The at molecular level ramate (circular) naphthenic structure ensures a flexible product which can be used for various formulations. The microcrystalline wax blends can be blended and customized on request.
The Usocore microcrystalline waxes for pharmaceutics and cosmetics conform to the latest international Pharmacopoeia standards, amongst others, the Ph.Eur., USP and JP. They are moreover in conformity with the national purity standards of BP, DAB and the French Codex.
They are also in conformity with directives FDA 21 CFR 172.886 and 21 CFR 178.3710 for the direct contact with foods and USDA H1, the standard for lubricants in the food processing industry.
Additionally, the microcrystalline waxes are in conformity with EC Directive 2002/72/EC-Plastics Directive - reference 95859 and the recommendations from Colipa for foodstuffs and cosmetic applications. These microwaxes are registered as a food additive under E 903.
