Embodiment 1-4

[0071] Examples 1-4 provide a gel containing camellia extract with after-sun repairing effect, and its components and percentages are shown in Table 1. Its preparation method is as follows:

[0072] 1) Add water, aloe vera leaf juice, thickener, and sodium hyaluronate into the emulsification pot in sequence, stir and disperse evenly, homogenize for 5 minutes, homogenize at a frequency of 45 Hz, and stir at a frequency of 20 Hz to obtain a mixed solution;

[0073] 2) Heat the mixed solution to 80-85°C, add an appropriate amount of pH regulator (sodium hydroxide), adjust the pH to neutral, and then lower the temperature;

[0074] 3) When the temperature is lowered to 70-80°C, add preservative, dissolve and stir evenly;

[0075] 4) Pre-disperse asiaticoside and dipotassium glycyrrhizinate with water, heat to 40-50°C, fully stir until completely transparent, and add when the temperature of the emulsification pot cools down to 40-50°C;

[0076] 5) When the temperature of the emul...

Abstract

The invention provides camellia extract-containing gel with an after-sun repair effect and a preparation method thereof. The gel is prepared from the following components in percentage by weight: 5 to20 percent of camellia extract inclusion; 10 to 40 percent of aloe leaf juice; 0.1 to 1 percent of asiaticoside; 0.1 to 1 percent of radix sophorae flavescentis extract; 0.1 to 1 percent of beta-glucan; 0.01 to 0.2 percent of dipotassium glycyrrhizinate; 0.01 to 0.1 percent of sodium hyaluronate; 0.1 to 1 percent of a thickening agent; 0.1 to 1 percent of a preservative; and the balanced of deionized water. The gel with the after-sun repair effect also comprises a pH regulator which is added to adjust the pH value to be neutral. According to the invention, a plurality of functional componentsare compounded according to an optimal ratio, so that the gel can effectively relieve skin inflammation, repair skin barrier, supplement water and preserve moisture, and can effectively relieve skindiscomfort caused by strong sunlight irradiation.

Description

technical field [0001] The invention relates to the technical field of cosmetics; in particular, it relates to a gel containing camellia extract and having the effect of repairing after sun exposure and a preparation method thereof. Background technique [0002] In summer, if workers who work outdoors for a long time cannot take effective protective measures, after strong sunlight exposure, ultraviolet rays will irritate the skin to a certain extent, resulting in the release of a series of inflammatory mediators. For example, keratinocytes in the epidermis release a large number of free radicals under the action of ultraviolet rays. Free radicals can degrade phospholipid molecules in the cell membrane and synthesize primary inflammatory factors under the action of enzymes. Another way for free radicals is to up-regulate the nuclear transcriptase NF- kB, promoting DNA to express more secondary inflammatory factors tumor necrosis factor TNF-α and interleukin IL-1. Inflammator...
