Abstract

The invention discloses an antioxidant plant essence skin care lotion, which is prepared from the following raw materials: 2 to 4 percent of jojoba oil, 1.5 to 2 percent of squalane, 0.35 to 0.5 percent of nicotinamide, 0.5 to 1 percent of polyglyceryl stearate, 1.5 to 2 percent of tocopheryl acetate, 10 to 12 percent of glycerol, 0.05 to 0.1 percent of methylparaben, 0.2 to 0.3 percent of allantoin, 0.2 to 0.5 percent of mannan, 3 to 5 percent of kenaf leaf extract and the balance of water. The emulsion prepared by the invention is good in whitening and tightening effects and mainly adopts a pure natural plant formula; doped zinc oxide nanoparticles are also used, so that the optical forbidden band width is reduced and the activation energy is reduced after doping, the reaction is more facilitated, the oxidation resistance of the finished product is greatly improved, and the storage is facilitated; the emulsion is uniform in texture and relatively good in stability; the sensitization is low, and the range of audiences is wide.

Description

technical field [0001] The invention relates to the technical field of daily chemical products, in particular to an antioxidant plant essence skin care emulsion and a preparation method thereof. Background technique [0002] Plants contain a variety of skin care nutrients, among which polysaccharides not only have various pharmacological effects such as anti-oxidation, anti-tumor, anti-aging, anti-inflammation, etc., but also have a large number of hydrophilic bases in their structure, which makes them have better skin care properties when used externally. Its water absorption, radiance, emulsification and film-forming properties, etc., can be used in cosmetics to produce moisturizing, repair damaged skin, delay aging and other effects. Skin care lotions made of plant extracts are often accompanied by oxidative deterioration caused by light and bacteria, which reduces the content of active ingredients and affects the various functions of skin care lotions.
