Extract of Polygonatum odoratum in the application of whitening products
Abstract：The main research topic is the whitening effect of Polygonatum odoratum extract in whitening products,And the Polygonatum extract and Chrysanthemum collaboration with whitening effect.Through the experiments in five samples with 2%, 4%, 6%, 8%, 10%, polygonatum odoratum extract,To observe the containing 2%, 4%, 6%, 8%, 10% of Polygonatum odoratum sample in -18 degrees, 48 degrees, normal temperature and light stability, time of a month, the color change during the sample, pH change and the change in viscosity. With whitening in vitro test to verify the jade bamboo rysanthemum extract and inhibition of tyrosinase. The ame method of mixed liquid of Polygonatum odoratum extract and white chrysanthemum (Chrysanthemum white square bamboo) stability in the sample and whitening effect.After the test，2%, 4%, 6%, 8%, 6%, five add amount of jade bamboo extract respectively in the emulsion system of pH, viscosity changes are within the normal range, conform to the cosmetic standard QB/T2286-1997, the color of the jade bamboo extract emulsion system there is no obvious change.Respectively 2%, 4%, 6%, 8%, 6% in bamboo chrysanthemum extract emulsion system, 8%, 10% samples in both the amount of the oil layer, while the other sample pH, viscosity changes were within the normal range, and color no obvious change, also conforms to the cosmetic standard QB/T2286-1997. White jade bamboo bamboo chrysanthemum extract and beauty have inhibition of tyrosinase whitening effect, and inhibition rate higher than jade bamboo chrysanthemum beauty white bamboo extract, jade bamboo and chrysanthemum morifolium extract have synergies effect.
