Embodiment 1

[0018] Embodiment 1: treatment sunscreen spray, containing diisopropyl methyl cinnamate 7%, zinc oxide 2.5%, jojoba oil 4%, Sophora japonica extract 5.5%, capric glyceride 3.5%, propylene glycol 0.6%, 0.5% of propylparaben, 0.7% of glyceryl monostearate, 0.7% of carbomer-9340.7%, 8% of ethanol, and the balance is water, prepared into a 25ml spray.

Embodiment 2

[0019] Embodiment 2: treatment sunscreen spray, containing diisopropyl methyl cinnamate 7%, zinc oxide 2.5%, jojoba oil 4%, Sophora japonica extract 5.5%, capric glyceride 3.5%, propylene glycol 0.6%, 0.5% of propylparaben, 0.7% of glyceryl monostearate, 0.7% of carbomer-9340.7%, 8% of ethanol, and the balance is water, prepared into a 75ml spray.

experiment example 1

[0024] Experimental Example 1, Determination of Anti-free Radical Ability

[0025] Taking the sunscreen sprays prepared in Example 1 and Comparative Examples 1-3 of the present invention as examples, the ability to resist DPPH free radicals was measured. First, accurately weigh 20mg of DPPH (1,1-dimethylbenzylphenylhydrazine), and dissolve it in a 250mL volumetric flask with absolute ethanol. The concentration of DPPH is 2×10 -4 mol / L. Mix well, and after standing in the dark at room temperature for 30 minutes, measure the absorbance value at a wavelength of 517nm. The same measurement was repeated 3 times. The results of the experimental dosage and DPPH clearance rate are shown in Table 1.

[0026] DPPH free radical scavenging rate (%)=[(1-A sample-A blank) / A control]×100%

[0027] A sample: the absorbance value of the sample at a wavelength of 517nm.

[0028] A Blank: Absorbance value of blank at 517nm wavelength.

[0029] A control: the absorbance value of the control...

Abstract

The invention relates to a sunscreen spray and a preparation method thereof. The sunscreen spray comprises 5%-9% of diisopropyl methyl cinnamic acid ester, 1.5%-4.5% of zinc oxide, 3%-8% of jojoba oil, 2%-7.5% of flora sophorae extract, 2.5%-5.5% of caprin, 0.05%-1% of propylene glycol, 0.05%-0.8% of propylparaben, 0.5%-1.2% of glycerin monostearate, 0.5%-1.2% of Carbomer-934, 2%-9% of ethyl alcohol and the balance of water. The sunscreen spray has the advantages that several kinds of sunscreen components are matched to be dispensed, and in this way, effective components go deep into the centers of cells on the deep layer of the skin; the compatible medicine components have the synergetic effect, are resistant to water and sweat and long in sunscreen time and together play a role in resisting to ultraviolet rays.

Description

technical field [0001] The invention belongs to the field of cosmetics, and in particular relates to a sunscreen spray and a preparation method thereof. Background technique [0002] With the development of society, the environment around people is deteriorating day by day, and the sharp increase of work pressure and life pressure makes people have more and more bad living habits, which put a lot of pressure on the skin. Ultraviolet rays and air pollution are very harmful to the skin. The ultraviolet radiation in the sun is a light wave that is harmful to the human body. If you travel, work or sunbathe in the open air for a long time, you may receive too much ultraviolet radiation. Cause erythema, accelerate skin aging, and even lead to skin cancer. In recent years, due to the continuous expansion of the ozone layer, the harm of ultraviolet radiation cannot be underestimated. UVA and UVB ultraviolet rays are the main hazards to the human body in ultraviolet rays. Defense a...
