Plant butters have multiple properties for cosmetic formulations :
- they are natural texturizers used to thicken the creams and give them the desired texture;
- they also have active properties, such as moisturising, nourishing, repairing, and soothing;
- they reinforce the hydrolipidic film of the skin and improve its elasticity. It protects it from external aggressions and helps it fight effectively against aging.
The manufacturing process of butters for cosmetics is a key, as with the vegetable oils. Pulp, kernels, seeds or any other raw material, from which the butter is made, is first crushed or macerated to extract the fat. During the manufacturing of an emulsion, the butter is added hot during the fatty phase. The refining of butters, like that of vegetable oils, ensures better preservation of the product, and avoids the oxidation responsible for the well-known phenomenon of rancidity. It can also regulate its colour and smell. Butters are active formulants also used as natural thickeners ideally suited for the formulation of emulsions, balms or creams for the skin, for the hair, as well as cutaneous or capillary masks. With their rich texture, they provide care products with real comfort during application and ensure ease of spreading. They have many benefits in the care for dry and dull hair, or dry skin.
