Problems solved by technology

Physical sunscreens are thick and heavy, which is a burden on the skin in summer. It is easy to produce oil and clog pores, but it is not easy to cause skin sensitivity; chemical sunscreens are light and thin, the skin breathes smoothly, and the oily texture is easy to absorb, but sensitive skin cannot adapt
At the same time, in order to increase the whitening effect, some manufacturers do not hesitate to add heavy metals such as lead and mercury and fluorescent whitening agents, which will cause damage to the skin.
Moreover, the functions of commercially available sunscreens a...

Embodiment 1-3

[0034] The preparation of embodiment 1-3 sunscreen

[0035] The formula is shown in Table 1:

[0036] Formulation of table 1 sunscreen composition

[0037]

[0038]

[0039] Above-mentioned formula preparation process is as follows:

[0040] (1) Preparation of pomegranate extract

[0041] Take fresh pomegranate peel from Mengzi, Yunnan → wash → dry at a constant temperature of 45°C → pulverize → accurately weigh 10g of powder → add 200ml of butanediol solution with a volume fraction of 60% (solid-liquid ratio 1:20, pH = 3.0) → ultrasonic Extract for 40min (extract 3 times) → filter and concentrate in vacuum → finished pomegranate extract.

[0042] (2) Solution preparation

[0043] A, Magnolia officinalis bark extract solution preparation

[0044] Accurately weigh 1 g of Magnolia officinalis bark extract, dissolve it with 1,3 butanediol, and prepare a 1:20 butanediol solution for later use.

[0045] B, pomegranate extract solution preparation

[0046] Accurately we...

Embodiment 4

[0064] The influence of embodiment 4 peony seed oil content on the sunscreen performance of sunscreen composition

[0065] The test is provided with 5 samples, and the preparation method of samples 1-5 is the same as in the example, wherein the peony seed oil content is successively 1 part, 4 parts, 7 parts, 10 parts and 13 parts, and the contents of other components are the same as in example 1, then the sample 4 is exactly the same as Example 1, and the sun protection property of the product under 6 wavelengths of 280nm, 290nm, 300nm, 310nm, 320nm and 330nm is mainly measured. Assuming that the quartz sheet is used as biological materials such as the stratum corneum and epidermis, sunscreen samples are coated on it, and their absorbance (light transmittance) values ​​are measured using a UV spectrophotometer. According to the size of absorbance (light transmittance), evaluate the sun protection performance of the product. The determination method is as follows:

[0066] (1...

Embodiment 5

[0077] Embodiment 5 moisturizing performance test

[0078]6 parts of each of Examples 1-3, glycerin and hyaluronic acid were divided into 2 groups, each sample was mounted on a watch glass with a diameter of 4 cm, and weighed. The first group of samples was tested for moisture absorption rate under high humidity conditions, that is, placed in a desiccator filled with silica gel and saturated ammonium sulfate aqueous solution with a relative humidity (RH) of 81% at room temperature (25°C) for 24 hours and then accurately weighed. Heavy. The second group of samples was also used for the determination of moisture absorption under low humidity conditions, that is, they were placed in a vacuum desiccator with a relative humidity (RH) of 43% and a vacuum degree of -0.1 MPa for 24 hours and then accurately weighed. From the mass difference of the sample before and after moisture absorption, the moisture absorption rate is calculated according to the following formula:

Abstract

The invention discloses a pure natural multiple-effect nourishing sunscreen cream containing peony seed oil and a preparation method thereof. The pure natural multiple-effect nourishing sunscreen cream consists of peony seed oil, high-quality olive emulsified wax, cananga odorata hydrolat, deionized water, trehalose, a 1% macromolecular sodium hyaluronate solution, a 1% lower-molecular sodium hyaluronate solution, an aloe vera gel stock solution, a red pomegranate extract, a Silasoma MEA ultraviolet absorbing inclusion, a particulate titanium dioxide dispersion liquid, pentanediol, 1,3-butanediol, a magnolia bark extract and an antibacterial agent. The pure natural multiple-effect nourishing sunscreen cream can be effectively resistant to ultraviolet radiation damage to the facial skin, prevent the facial skin from being tanned and sunburned, meanwhile nourish the facial skin and infiltrate into facial skin cells while moisturizing the facial skin, is very easily absorbed and utilized by the skin cells, can comprehensively provide various types of nutrition required by the facial skin and can further quickly repair damaged cells, restore the activity of the facial skin cells, decrease wrinkles, restore skin elasticity and white and make the face reappear youthful luster.

Description

technical field [0001] The invention belongs to the technical field of preparation of daily cosmetics, and relates to a composition for anti-ultraviolet radiation, anti-oxidative aging of skin and inhibition of melanin formation, in particular to a pure natural multi-effect nourishing sunscreen containing peony seed oil and a preparation method thereof. Background technique [0002] While the sun brings light and warmth to the earth, it also produces a large amount of ultraviolet rays. According to the length of the wavelength, ultraviolet rays can be divided into ultraviolet A (UVA, 320-400nm), ultraviolet B (UVB, 280-320nm) and ultraviolet C ( UVC, 200-280nm) three kinds, UVA dominates sunlight aging, while UVB is the culprit of skin sunburn, and UVC is highly carcinogenic, but fortunately, UVC is absorbed by the atmosphere. Ultraviolet rays UVA and UVB can penetrate the dermis, causing sunburn, tanning and peeling of the skin, which will lead to premature aging of the ski...
