Abstract

The invention provides a nutritional preparation with selective whitening spot-removing efficacy and application thereof in medicinal cosmetics. The nutritional preparation is prepared by compounding of azelaic acid oligopeptide, ascorbic acid oligopeptide, tranexamic acid oligopeptide, retinoic acid oligopeptide, kojic acid oligopeptide, hydroxy acid oligopeptide, ellagic acid oligopeptide and other raw materials, and the oligopeptide is one or a compound of multiple of dipeptide, tripeptide, tetrapeptide, pentapeptide, hexapeptide, heptapeptide, octapeptides, nanopeptide and decapeptide. The medicinal cosmetics prepared form the nutritional preparation are original liquids, water preparations, masks, cream lotion, liquid foundation cream, gel, essence and other preparation forms. The cosmetics are prepared by compounding of the nutritional preparation, penetrating agents and auxiliary materials. The penetrating agents are plant essential oils, azone, carbitol and other medical penetrating agents. The auxiliary materials are thickeners, emulsifiers, packet agents, wetting agents, emollients, flavoring agents, preservatives and solvents which are used as main medicinal raw materials. A large number of clinical trials prove that the medicinal cosmetics prepared form the nutritional preparation have good selective whitening spot-removing and nutritional efficacy for the skin of human body.

Description

technical field [0001] The invention belongs to the cross field of traditional Chinese medicine technology, bioengineering technology and chemical synthesis technology. It relates to the preparation of a compound formulation with selective whitening and freckle-removing effects, and the application of the formulation in cosmetics. Background technique [0002] Cosmetics with low stimulation efficacy have always been a hot spot pursued by society. However, the current functional cosmetics in the society cannot always meet everyone's requirements. Starting from the theory of traditional Chinese medicine, the company looks for effective prescriptions to ensure that its products have clear efficacy; using modern chemical positioning synthesis technology, the key raw materials in the prescriptions are synthesized according to the designed route. The key raw materials in the formula all come from oligopeptides (dipeptide to decapeptide) in genetic engineering, so as to ensure th...
