Embodiment

[0053] According to the formula in the following table, each component was fully mixed to prepare a cosmetic base (sample A), and purslane extract, scutellaria baicalensis extract and / or hydrolyzed wheat protein were added to the base formula to prepare each sample. The comparison test is carried out by adding in combination, OP-tometrics SPF-290S tests the SPF value, takes the average value of multiple tests, and records the test results.

[0054] In the present invention, the groups of the samples (B1, B2, B3, C1, C2, C3 and D1, D2, D3, E, B11, B21, B31, C11, C21, C31 and D11, D21, D31) Fully mixed, the obtained sunscreen lotion has a pleasant smell, and when sprayed on the skin surface, it is refreshing and has a good skin feel. After repeated heat resistance (40±1°C, no turbidity after 24 hours of recovery to room temperature), cold resistance (-15±1°C, 24 hours after recovery of room temperature, the system is normal, no turbidity) destructive tests, the sensory indicator...

Abstract

The invention provides a natural sunscreen composition with synergistic effect on sun protection factor (SPF) value of cosmetics and the cosmetics containing the composition. The composition is formed by compounding and combining purslane extract, baical skullcap root extract and hydrolyzed wheat protein, wherein the baical skullcap root extract is the extract which is obtained by distilling and extracting root of scutelleria baicalensis georgi with water, glycerol or ethylene glycol and then evaporating the vast majority of solvent and water; the purslane extract is the extract which is obtained by distilling and extracting stem leaf of the over-ground part of purslane serving as portulaca annual succulent with water or ethylene glycol and then evaporating the vast majority of solvent and water; and the hydrolyzed wheat protein is a cross-linked polymer of the hydrolyzed wheat protein and polyvinyl pyrrolidone (PVP), which has the molecular weight of between 35,000 and 45,000. The sunscreen composition is added into the cosmetics and has the synergistic effect on the SPF value in the cosmetics.

Description

technical field [0001] The invention relates to a natural sunscreen composition, in particular to a natural sunscreen composition which can be added to cosmetics and has synergistic ability to the SPF value of cosmetics, and belongs to the field of cosmetic additives. Background technique [0002] The main function of sunscreen cosmetics is to prevent sunscreen, or prevent the adverse effects of ultraviolet (Ultraviolet Radiation) radiation on human skin. Ultraviolet rays are referred to as UVR, which is a kind of non-ionizing radiation with a wavelength of 100-400nm. Usually, ultraviolet rays with a wavelength of 100-290nm are called short-wave ultraviolet rays (UVC), and ultraviolet rays with a wavelength of 290-320nm are called medium-wave ultraviolet rays. (UVB), ultraviolet rays with a wavelength between 320 and 400nm are called long-wave ultraviolet rays (UVA). Since short-wave ultraviolet rays (UVC) are completely absorbed by the atmospheric ozone layer, only medium-...
