Abstract

The invention relates to a functional microcapsule with the diameter of 0.2-3.5 mm and a preparation technology thereof. The microcapsule mainly comprises active ingredients, vegetable oil, sodium alginate, chitosan, soya bean lecithin, PEG-40 stearate, water and other auxiliary ingredients. The method comprises the following steps of: (1) dissolving sodium alginate in water to obtain A; (2) preparing a water solution of hydrophilic active ingredients, PEG-40 stearate and other auxiliary ingredients to obtain B; (3) while stirring, adding B into A to obtain C; (4) dissolving hydrophilic active ingredients and soya bean lecithin in vegetable oil to obtain D; (5) while quickly stirring, adding C into D to obtain E; (6) while stirring, adding E into a chitosan solution to form a microcapsule; (7) washing the microcapsule obtained in step (6) with the 0.1-0.4% chitosan solution; and (8) drying the microcapsule by a spray drying or freeze drying method.

Description

technical field [0001] The field of daily chemicals of the present invention specifically relates to a preparation method of microcapsules for hair. Background technique [0002] After decades of development, cosmetics technology has reached a considerable level, subdivision, functionality, and deep-seated needs have become hot spots, and new active ingredients have been introduced one after another, but nutritional active ingredients, enzyme preparations and other active ingredients The stability of cosmetics is often relatively poor, and they are also sensitive to the environment. How to effectively solve the stability problems of active ingredients in the process of cosmetic preparation, storage, and transportation, and how to make active ingredients break through the surface of skin, hair and other receptors, and go deep into their inner play The role has become a problem to be solved. The development of encapsulation technology such as microcapsules has brought dawn to...
