Problems solved by technology

These preservatives have a very small molecular weight and are easily absorbed by the skin and accumulate in the dermis. Long-term use will cause potential harm to the skin. Some will affect the skin’s barrier function, loosen the keratinocytes, and cause the cells to be rough and sensitive.

Embodiment 1

[0016] The existing extracts of Pulsatilla chinensis, extracts of chinensis, and extracts of Usnea barbata are mixed in a conventional way at a ratio of 1:1:1 by mass at room temperature, which is a new type of preservative to be added in skin care.

[0017] The preservative is added in an amount of 0.5%-2.5% in skin care products.

Embodiment 2

[0019] The existing extracts of Pulsatilla chinensis, extracts of chinensis, and extracts of Usnea barbata are mixed in a conventional way at a ratio of 1:2:1 by mass at room temperature, which is a new type of preservative to be added in skin care.

[0020] The preservative is added in an amount of 0.5%-2.5% in skin care products.

Embodiment 3

[0022] The existing extracts of Pulsatilla chinensis, extracts of chinensis, and extracts of Usnea barbata are mixed in a conventional manner at a mass ratio of 2:2:1 at room temperature, which is a new type of preservative to be added in skin care.

[0023] The preservative is added in an amount of 0.5%-2.5% in skin care products.

[0024] The new preservative can kill 99.8% of bacteria and microorganisms by the total number of bacteria tested in the laboratory. After 6 months, 12 months, 18 months, and 24 months, the total number of bacteria tested respectively is within the scope of national cosmetic regulations. This technology can prolong the service life of skin care cosmetics, replace the original chemical preservatives, and is safe for long-term use with low usage. Compared with the use of traditional preservatives, it can reduce the skin allergy caused by traditional preservatives by 38%-46%.

Abstract

The invention relates to the field of skincare products, in particular to a novel preservative for skincare products and application fields thereof. Specifically, the novel preservative is prepared from radix pulsatillae extract, zanthoxylum piperitum fruit extract and usnea barbata extract according to the mass ratio of (1-2):(1-2):1. The preservative used for skincare products not only has a good preservative effect, but also is a natural plant composition which does not cause skin allergy or break the skin barrier, so that health problems caused by traditional preservatives and percutaneous toxins can be reduced or avoided.

Description

technical field [0001] The invention relates to the field of skin care products, in particular to a novel preservative in skin care products and its application field. Background technique [0002] With the rapid economic development, skin care products have become the mainstream of modern consumption. In the process of production and storage of skin care products, spoilage is easy to occur. Since the raw materials of skin care products contain a lot of oil, vitamins, amino acids and water, these are all kinds of nutritional factors required by microorganisms, which are easy to breed bacteria and microorganisms, which will cause product corruption and eventually lead to product quality problems. Deteriorated cosmetics are prone to allergies, skin infections, and serious life-threatening. In order to avoid the above situation, a large number of skin care products currently on the market add single or multiple preservatives to varying degrees, such as: imidazolidinyl urea, c...
