Taurine (Taurine) is a sulfur-containing amino acid with a simple structure in animals, has a chemical name of 2-aminoethanesulfonic acid, is odorless, has neutral dilute solution, is stable to heat, and is combined with cholic acid in human and animal bile to exist in a combined form. Researches prove that the taurine has the capability of activating skin cells and can continuously provide quick and durable energy supplement and multiple protection for young skin. The taurine also has the effects of improving the immunity of the skin and resisting the invasion of the external environment to the skin.
Compared with the prior art, the invention has the beneficial effects that: the amino acid crystallization suspension technology has the functions of moisturizing in a washing-off product and also has a good effect in a resident product. Taurine has the functions of moisturizing and relieving skin, and is amino acid required by human body. The precipitated taurine crystals can be uniformly distributed in the composition by adding the supersaturated active amino acid component, namely taurine, and matching with the specific complex polyol, the emulsion stabilizer and the suspension stabilizer for use. The addition of the complex polyol and the emulsion stabilizer can reduce the solubility of the taurine in the deionized water, so that crystals can be more easily separated out. The selected acrylic acid (ester)/behenyl alcohol polyether-25 methacrylate copolymer has the suspension stabilizing effect, can ensure that precipitated taurine crystals are uniformly distributed, and has a spatial network structure which can form steric hindrance and can promote the directional crystallization of the taurine crystals. The ice crystal amino acid crystallization composition can provide high-efficiency skin care effect when being applied to a resident cosmetic product. In the actual use process, the taurine crystals can be rapidly broken and the high active concentration can be kept by the action of external force such as friction, beating and the like, so that the skin care capability of the resident cosmetic is enhanced.

As can be seen from the experimental results of Table 1, the ice crystal amino acid crystallization composition of example 3 had a high crystallization yield of 96.28%, while the crystallization yields of comparative examples 1 to 4 were relatively low.
