Abstract

The invention provides a sunscreen mist spray which comprises the following raw materials: methoxy-cinnamic acid ethylhexyl acrylate, octocrilene, bi-ethyl hexyloxyphenol methoxyphenyl triazine, butylmethoxy-dibenzoyl methane, natural phospholipid, absolute ethyl alcohol, titanium dioxide, zinc oxide, polydimethylsiloxane, polydimethylsiloxane, an emulsifier, 1,2-pentanediol, disodium hydrogen phosphate, sodium alginate, mannitol, sodium hyaluronate and water. A preparation method comprises the following steps: firstly, preparing lipidosome from chemical sunscreen agents, and together with physical sunscreen agents, preparing the sunscreen mist spray. By adopting the sunscreen mist spray, on one hand, irritation of the chemical sunscreen agents to skin can be reduced, on the other hand, the sunscreen agents can be uniformly clung to the surface of skin, the action time of the chemical sunscreen agents is prolonged, the overall sunscreen effect of the mist spray is greatly improved, and the use amount of the mist spray can be reduced.

Description

technical field [0001] The invention belongs to the technical field of cosmetics, and in particular relates to a sunscreen spray and a preparation method thereof. Background technique [0002] As we all know, proper amount of ultraviolet radiation can disinfect and sterilize, provide vitamin D needed by the human body, enhance resistance, promote metabolism, and are very beneficial to the development and health of the human body. However, excessive ultraviolet radiation will cause photodamage to the skin. From a genetic point of view, ultraviolet rays can cross-link the pyrimidines of the two bells to form a pyrimidine dimer, thereby significantly changing the three-dimensional conformation of DNA and blocking Replication and transcription of damaged DNA. Macroscopically, long-wave ultraviolet rays (UVA320-400nm) can accelerate the process of melanocytes transforming from tyrosine to melanin, induce photosensitization, skin photodegeneration and phototoxicity. UVA has been...
