This application provides a sunscreen-enhancing composition, a
sunscreen cream, and a method for preparing the same, relating to the field of daily
cosmetics. The raw materials of the sunscreen-enhancing composition, by weight, include: 0.2-2 parts of
sclerotium gum, 1-10 parts of jojoba esters, and 0.5-5 parts of
Lactobacillus / rice
fermentation product. The
Lactobacillus / rice
fermentation product adsorbs and encapsulates the sunscreen agent through a
helical cavity structure, achieving uniform dispersion; the
sclerotium gum forms a three-dimensional network gel film through
hydrogen bonding cross-linking, fixing the sunscreen particles and improving
erosion resistance; the jojoba esters fill the gaps between particles through lipid spreading and fusion, enhancing waterproof and sweat-resistant capabilities; the three components together construct a triple film-forming mechanism of "adsorption-encapsulation-molecular entanglement-lipid spreading," solving the problems of sunscreen agent aggregation and
sedimentation, and low protective efficiency, achieving a sunscreen film that is "uniform and dense, leak-free, and highly stable," significantly improving the durability of SPF / PA values.
