Problems solved by technology

[0004] 2. Airtightness: the one-package has poor airtightness, and there is no pouch to protect the material body packaging
[0005] 3. Purity of the material body: One-package is a mixture of gas and material, the material body is not pure enough to optimize product quality, and poor sealing may cause other gas bacteria to come in and contaminate the material body, resulting in deterioration of the material body
[0006] 4. Spraying effect: The atomization effect of the sprayed material in one-package is poor, and the impact force is relatively large, so the skin absorption is relatively not ideal
[0009] And the use of binary spray sunscreen spray is less, and the effect is not good.

Embodiment 1～8 and comparative example 1～3

[0040] The formulations of the sunscreen spray described in Examples 1 to 8 and Comparative Examples 1 to 3 are shown in Table 1, and the preparation method of the sunscreen spray described in Examples 1 to 8 and Comparative Examples 1 to 3 comprises the following steps:

[0041] 1. Preparation of slurry: Mix and stir C12-15 alcohol benzoate, titanium dioxide (CI77891) and squalane evenly, and then grind it three times with a three-roller until it is completely dispersed;

[0042] 2. C20-22 alcohol phosphate (and) C20-22 alcohol, glyceryl stearate (and) PEG-100 stearate, polydimethylsiloxane, cyclopentasiloxane (and) Cyclohexasiloxane, tocopheryl acetate, butylmethoxydibenzoylmethane, VP / hexadecene copolymer, methylparaben, and propylparaben are added to the oil phase pot in turn, and heated Stir and heat up to 75-85°C;

[0043] 3. Add the slurry prepared in step 1, continue to stir and heat up to 75-85°C;

[0044] 4. Put deionized water, glycerin, butylene glycol, allantoin, ...

Embodiment 9

[0054] In order to verify the skin feel and atomization effect of each group of sunscreen sprays, 88 volunteers with oily or mixed skin, aged 18 to 35, were selected and divided into 11 groups, with 8 people in each group, and tried Examples 1 to 8 respectively. 1. For the sunscreen spray described in Comparative Examples 1 to 3, the skin feel and atomization effect are scored as 5 points, 4 points, 3 points, 2 points, 1 point, and 0 points in order from good to bad, and the average value of the statistical test is calculated. The test results are shown in Table 2.

[0055] Table 2 Skin feel and atomization effect test results of Examples 1-8 and Comparative Examples 1-3

[0056]

[0057] The above test data show that the skin feel of Examples 1-8 is better than that of Comparative Examples 1-3, and the skin feel and atomization effect of Example 1 are the best.

Embodiment 10

[0059] The sunscreen sprays of Examples 1-8 and Comparative Examples 1-3 are tested for product performance, and the specific testing methods are as follows:

[0060] 1. Accurately weigh 100mg of each sunscreen spray sample into a 50ml bottle, add a mixture of absolute ethanol and absolute ether in a ratio of 1:1 as a solvent to make a solution. Pour the prepared solution into a 1cm×1cm×5cm quartz colorimetric cell, and measure the ultraviolet light transmittance in the wavelength range of 290-400nm in a well-adjusted ultraviolet spectrophotometer.

[0061] 2. For volunteer subjects, first use the skin moisture and oil content test pen to test the water and oil content of the skin when no sunscreen is applied. After using the above sunscreen, use the test pen to test the water and oil content again.

[0062] 3. The specific test results are shown in Table 3.

Abstract

The invention relates to sunscreen spray which comprises, in weight percent, 1-9.5% of titanium dioxide, 2-10% of octyl methoxycinnamate, 0.5-7.5% of methylene dibenzo-triazolyl tetramethyl butylphenol and 0.1-5% of butyl methoxyl dibenzoyl methane. Physical sunscreen agents (the titanium dioxide) and chemical sunscreen agents (the octyl methoxycinnamate, the methylene dibenzo-triazolyl tetramethyl butylphenol and the butyl methoxyl dibenzoyl methane) are compounded to prepare the sunscreen spray, so that the sunscreen spray has good skin feelings and sunscreen effects.

Description

technical field [0001] The invention belongs to the technical field of cosmetics, and in particular relates to a sunscreen spray. Background technique [0002] At present, the one-component spray used in general sunscreen spray packaging, the two-component spray is a safer form, and has the following advantages compared with the one-component spray: [0003] 1. Safety First, the propellant of the one-component spray is generally flammable and explosive dimethyl ether, propylene butane and other components, and it is strictly forbidden to bring it on the plane and high-speed rail. The propellant of the binary spray is compressed air or nitrogen, which is safer and can be carried on high-speed rail and airplanes. [0004] 2. Airtightness: The one-package has poor airtightness, and there is no pouch to protect the material body packaging. Binary packaging has high airtightness, and is a multi-protection material packaging system formed by valves, four-layer vacuum bags, and a...
