Cera Bellina is a hydrophilic derivative of natural beeswax in which the free fatty acids have been converted to polyglycerols esters through the use of heat and vacuum. Elimination of the free fatty acid functionalities in beeswax improves the oil gelling and oil retention capability.
Products formulated with Cera Bellina and natural as well as synthetic oils produce remarkably stable, smooth gels. This property is also beneficial in emulsion products, where its hydrophylic properties enable it to act as a coemulsifier and its rheology modifying properties lend increased formulation stability. In decorative cosmetics, Cera Bellina helps to break up pigment agglomerates by forming a gel network thereby maintaining an even distribution of ingredients. Cera Bellina also suppresses the fatty acid, fatty alcohol migration and oil syneresis in finished stick formulas.
Cera Bellina has the unique ability to give stability by forming non-granular gels of liquid oils. Besides the consistency regulating properties of beeswax, Cera Bellina has the remarkable capability of inhibiting crystallization in the oil phase and therefore enhancing stability by preventing the formation of granules. This attribute can eliminate the graininess or rice granule effect that can occur when using shea and other natural butters in anhydrous formulations such as lip balms and lotion bars.
Cera Bellina also greatly improves stability in dispersions utilizing non-soluble components, such as organic and inorganic pigments, as well as mineral and polymer extenders.
