Problems solved by technology

In recent years, there have been endless reports of adverse reactions such as allergic dermatitis, irritant contact dermatitis, and contact urticaria caused by ingredients in sunscreens. Some products use a large amount of inorganic powdered sunscreens, causing skin pores to be blocked, causing skin inflammation, In response to skin lesions such as abscesses, many sunscreen products use chemically synthesized sunscreens to greatly increase the SPF (SunProtectionFactor) value and PA (ProtectionAntiUVA) value, but these sunscreens have poor photostability, are prone to light or oxidative degradation, and cause skin Sensitivity, redness and inflammation

Embodiment 1

[0033] Take 6g of dry aloe vera skin powder and add 30 times the mass of the extraction solvent. The mass fractions of the solvent are 20%, 30%, 40%, 50% and 60% ethanol solution, at a temperature of 25℃±3℃ Carry out ultrasonic extraction for about 30 minutes. After fully filtering with 0.22nm organic filter paper, take the filtrate, concentrate the filtrate to 0.3 times in a rotary evaporator, and transfer it to a vacuum drying oven at 55°C to obtain a fluffy solid. After being ground into powder, 5 times the mass of deionized water is added to dissolve to obtain an aloe extract for later use. Take 1.5ml of aloe extract and dilute to 5ml with absolute ethanol, take 1ml of diluent and react with 1ml of 2% magnesium acetate methanol solution for 30 minutes and then dilute to 10ml with deionized water. Use a 1cm cuvette to measure the difference in absorbance at 420nm before and after the reaction with the volume ratio of deionized water: methanol = 9:1 as a reference. The relati...

Embodiment 2

[0035] Take 6g of dry aloe skin powder, add 30 times the mass of extraction solvent, the choice of solvent is 60% ethanol solution, and perform ultrasonic extraction at 25℃, 35℃, 45℃ and 55℃ for about 30 minutes. After fully filtering the 0.22nm organic filter paper, take the filtrate, concentrate the filtrate on a rotary evaporator to 0.3 times, transfer it to a vacuum drying oven at 55℃ and dry to obtain a fluffy solid, grind it into powder and add 5 times the mass Dissolve in deionized water to obtain aloe extract for use. Take 1.5ml of aloe extract and dilute to 5ml with absolute ethanol, take 1ml of diluent and react with 1ml of 2% magnesium acetate methanol solution for 30 minutes and then dilute to 10ml with deionized water. Use a 1cm cuvette to measure the difference in absorbance at 420nm before and after the reaction with a mixture of deionized water: methanol = 9:1 in volume ratio as a reference. The relative intensity of the absorbance varies with extraction tempera...

Embodiment 3

[0037] Take 6g of dry aloe vera skin powder, add 10 times, 20 times, 30 times and 40 times the mass of the extraction solvent respectively. The choice of solvent is 40% ethanol solution, and perform ultrasonic extraction at 45℃±3℃ for 30 minutes Take the filtrate after fully filtering it with 0.22nm organic filter paper. Concentrate the filtrate to 0.3 times in a rotary evaporator, transfer it to a vacuum drying oven at 55°C and dry to obtain a fluffy solid, grind it into powder and add it 5 times the mass of deionized water is dissolved to obtain an aloe extract for use. Take 1.5ml of aloe extract and dilute to 5ml with absolute ethanol, take 1ml of diluent and react with 1ml of 2% magnesium acetate methanol solution for 30 minutes and then dilute to 10ml with deionized water. Use a 1cm cuvette to measure the difference in absorbance at 420nm before and after the reaction with a mixture of deionized water: methanol = 9:1 in volume ratio as a reference.

Abstract

The invention belongs to the technical field of daily care articles, and discloses a natural preservative children plant sunscreen lotion and a preparation method thereof. The natural preservative children plant sunscreen lotion is prepared from the following raw materials: cetearyl glucoside, monoglyceride, C16-18 alcohols, 26# white oil, methylsilicone oil, ethylenediamine tetracetic acid sodium, glycerin, propylene glycol, carbomer, allantoin, xanthan gum, triethanolamine, D-panthenol, aloe extract, bamboo leaf extract, lotus leaf extract, tequila extract, and deion. The natural preservative children plant sunscreen lotion has the advantages that by adding the plant extracts as sunscreen components and preservative components, the use of chemical synthetic sunscreen agents and preservatives is avoided, the irritation is reduced, the safety is improved, and the sunscreen lotion can be applied to children formula.

Description

Technical field [0001] The invention belongs to the technical field of daily care products, and specifically relates to a natural antiseptic children's plant sunscreen milk and a preparation method thereof. Background technique [0002] Compared with adults, children’s skin has huge differences in structure and function, including: 1) children’s skin is thin and soft, the outer stratum corneum of their skin is a single layer of cells, lacking a transparent layer; 2) children’s skin contains The water content is high, but due to the extremely low skin barrier function, the skin's water loss is also large; 3) Children's skin has low melanin content, thin pigment layer, high photosensitivity, poor UV resistance, and is easily burned by UV radiation. In addition, children’s outdoor activities are longer, and the cumulative amount of ultraviolet radiation increases. Therefore, the use of sunscreen cosmetics to resist the damage of ultraviolet rays to children's skin has become the ch...
