Natural plant sun cream and preparation process thereof

Abstract

The invention provides a natural plant sun cream which comprises the following main ingredients: water, glycerin, isooctyl palmitate, an aloe extract, a scutellaria baicalensis extract, a myrica rubra extract, fatty alcohol, bisabolol, polydimethylsiloxane and the like. The invention also provides a method for preparing the natural plant sun cream, and the method comprises the following steps of: putting glycerin, aloe extract, scutellaria baicalensis extract, myrica rubra extract, and water into an aqueous-phase pot, heating the obtained mixture until the obtained mixture is completely dissolved so as to obtain an A-phase matter; putting isooctyl palmitate, fatty alcohol, bisabolol, polydimethylsiloxane, cetyl polyethylene glycol / polypropylene glycol-10 / 1-dimethyl silscone, methylparaben and propyl hydroxybenzoate into an oil-phase pot, heating the obtained mixture until the obtained mixture is completely dissolved so as to obtain a B-phase matter; taking the essence as a C-phase matter; pumping the B-phase matter into a main emulsifying pot, and slowly pumping the A-phase matter into the emulsifying pot within 15-20 minutes under the condition of stirring; homogenizing the obtained product for 3 minutes; carrying out constant-temperature stirring on the obtained product for 30 minutes; after the obtained object is cooled, adding the C-phase matter into the obtained object, uniformly stirring the obtained mixture, and ageing the obtained product for 24 hours so as to obtain the sun cream.

Description

technical field [0001] The invention belongs to the technical field of cosmetics, and in particular relates to a natural plant sunscreen and a preparation process thereof. Background technique [0002] Sunshine is the "friend" of beauty. Appropriate sun exposure can accelerate skin blood circulation, increase the content of melanin in the skin, protect the skin, promote the production of vitamin D3 in the skin, and facilitate calcium absorption. Although only 5 percent of the sun's energy in ultraviolet light reaches the ground, its effect on the skin is extremely strong. The ultraviolet rays contained in sunlight can be divided into long-wave dark spot effect ultraviolet rays (UVA) with a wavelength of 320-400 nm, medium-wave erythema effect ultraviolet rays (UVB) with a wavelength of 280-320 nm, and short-wave ultraviolet rays (UVB) with a wavelength of 200-280 nm. UVC). UVA accounts for 10-20% of the total UV, and more than 95% of the radiation reaches the ground. It ca...

Problems solved by technology

Due to the shortcomings of the above two types of sunscreens, people want to find a sunscreen that combines all the advantages, has stable quality, has sunscreen function, and has no toxic and side effects. Using natural plant materials with sunscreen function as sunscreen can solve this problem. One problem, especially extracting active ingredients from plants and adding them to skin care products has more significant effects, mild effect, high efficiency, low price, and high antioxidant performance, such as CN102657589A "a kind of Rhodiola rosea sunscreen", which is based on Rhodiola daflora extract is a sunscreen additive, which has its advantages, but the main production areas of Rhodiola daflora are in Tibet, northwest Yunnan, and western Sichuan, and its active substances are 5-10 times higher than other varieties of the same kind , natural self-growth, can not be cultivated, mainly for medicinal purposes

Since there are sunscreens on the market that add natural plant extracts, they are generally oil-in-water sunscreens. Although this sunscreen is refreshing and easy to absorb, the heat resistance stability of the oil-in-water emulsion system is far less than that of the water-in-oil system. The heat-resistant stability of natural plant extracts requires an emulsion matrix with good heat-resistant stability to finally exert its special effects, and the oil-in-water type sunscreen is easy to be washed away by sweat, and the sun protection time is short, so It is of great significance to develop a new natural plant sunscreen skin care product
