Sun-blocking and moisturizing composition and preparation method thereof

Abstract

The invention provides a sun-blocking and moisturizing composition and a preparation method thereof. The composition is composed of following components including, by weight, 4-6% of propylene glycol laurate / ethyecellulose / propylene glycol isostearate, 1-2% of shea butter, 0.2-0.3% of tocopheryl acetate, 2% of ethylhexyl methoxycinnamate, 2.5% of butyl methoxydibenzoylmethane, 3-4% of isononyl isononanoate, 2% of decamethylcyclopentasiloxane, 1% of polydimethylsiloxane, 0.3-0.4% of an acrylic acid (ester) / C10-30 alkanolacrylate crosslinking polymer, 0.1% of xanthan gum, 0.02% of disodium EDTA, 0.02% of sodium hyaluronate, 3-4% of butanediol, 3-4% of glycerin, 3% of glyceryl polyether-26, 0.15-0.2% of an aminomethyl propanol / water premixed substance, 3% of water / butanediol / purslane extract, 0.5% of a bacteriostatic agent, 2% of a water / glycerin / phenoxyethanol / [beta]-glucan premixed substance and the balance deionized water. The sun-blocking and moisturizing composition is suitable for sensitive skin, has a touching-melt texture, can form a compact and soft residual film on a skin surface and enable active components to be absorbed better by the skin.

Description

Technical field [0001] The invention belongs to the field of daily chemical industry, especially the field of skin care products, and specifically relates to a sunscreen moisturizing composition and a preparation method of the sunscreen moisturizing composition. Background technique [0002] The skin is the human body’s first barrier against harmful substances such as bacteria, viruses, and dust from the outside world. When the skin is exposed to excessive ultraviolet light, it will damage the epidermal cells; activate tyrosinase, accelerate the synthesis of pigment, and destroy the skin’s moisturizing function. The skin becomes dry, which damages the elastic fibers in the dermis and produces fine lines. Under strong irradiation, it can also cause skin inflammation and burns. When there is an abnormal condition, it will become pigmented skin cancer. When the air temperature decreases, the stratum corneum of the skin cannot adjust enough moisturizing factors in time, the activity...

Problems solved by technology

However, surfactants can interfere with the skin's natural balance

In addition, creams containing emulsifiers have a thicker texture and cannot form a dense and soft residual film. When sweat and humidity change, active ingredients on the skin may be quickly taken away
