preparation example Construction

[0054] The preparation method of roselle flower extract in embodiment 1-5 and comparative example 1-2, comprises the following steps:

[0055] (1) Take the dried roselle calyx and grind it to 80 mesh to obtain roselle calyx powder;

[0056] (2) Mix roselle calyx powder and deionized water, the ratio of solid to liquid of the roselle calyx powder and deionized water is 1g:100mL, reflux extraction at 85°C for 3 times, each extraction time is 90min, collect The extract is concentrated under reduced pressure to a density of 1.6 g / mL to obtain a roselle calyx concentrate;

[0057] (3) After adding malic acid to the roselle calyx concentrate, use 45kHz ultrasound for 30min, the ultrasonic temperature is 65°C, the mass ratio of the malic acid to the roselle calyx concentrate is 0.2:10, and the ultrasonically treated roselle calyx is obtained Concentrate;

[0058] (4) Add 5-7% activated carbon according to the quality of the roselle calyx concentrate after ultrasonic treatment, cont...

Abstract

The invention provides a preparation method of a natural plant sunscreen cream, the sunscreen cream is prepared from a component A, a component B and a component C according to a mass ratio of (0.1-0.3): (1.3-1.5): (2-2.2), the component A is composed of a curcuma zedoary extract, a fructus amomi extract and a roselle flower extract; the component B is prepared from triacontyl PVP (Polyvinyl Pyrrolidone), bisabolol, dipotassium glycyrrhizinate, octyl polymethylsiloxane and dipropylene glycol; the component C is prepared from sunflower seed oil, a hydrogenated C6-14-chain olefin polymer, tetrahydromethylpyrimidine carboxylic acid and glycerol, according to the effects of different components in the sunscreen cream, different methods are used for preparing the sunscreen cream, the prepared sunscreen cream has good stability, the effective sunscreen time of the prepared sunscreen cream is as long as 4 hours, and the sunscreen coefficient is SPF50 < + > and PA < + + + >.

Description

technical field [0001] The invention relates to the field of sunscreens, in particular to a preparation method of natural plant sunscreens. Background technique [0002] The wavelength range of ultraviolet radiation (UVR) is 100-400nm, which can be divided into short-wave (UVC, 100-290nm), medium-wave (UVB, 280-320nm) and long-wave ultraviolet (UVA, 320-400nm) according to the length of the wavelength. A certain intensity of ultraviolet rays can disinfect and sterilize, promote bone development, and play a positive role in the growth of the human body, animals and plants. The skin is the body's physiological barrier, protecting it from pathogens, chemical or physical damage, but it is also the most vulnerable to UV damage. Excessive ultraviolet radiation can cause oxidative stress in the skin: skin erythema, pigmentation, skin aging, photosensitivity, and even induce skin tumors. Among them, UVA can cause skin dryness, wrinkling, loss of elasticity, and induce melanin pigm...
