Whitening lotion and preparation method thereof

Abstract

The invention belongs to the technical field of daily necessities, and particularly relates to whitening lotion and a preparation method thereof. The whitening lotion is prepared from the following raw materials: a pistacia weinmannifolia extract, an adenophora trachelioides maxim. extract, a liquorice root extract, a waltheria americana extract, rose flower water, bee milk, olive oil and deionized water. The invention further relates to the preparation method of the whitening lotion. The preparation method comprises the following steps: (1) preparation of the pistacia weinmannifolia extract and the liquorice root extract; (2) preparation of the waltheria americana extract and the adenophora trachelioides maxim. extract; (3) raw material mixing. By cooperation of four Chinese herbal medicines, namely pistacia weinmannifolia, adenophora trachelioides maxim., liquorice roots and waltheria Americana, the whitening lotion enhances the functions of whitening and maintaining the skin, so that the whitening effect is enhanced; the raw materials are natural non-irritant components, which achieve the whitening and moisturizing effects and have no irritation to the skin, so that the lotion can be used for a long time; a preparation process is easy to operate and relatively low in equipment requirement, guarantees the production quality and reduces the production cost.

Description

technical field [0001] The invention belongs to the technical field of daily necessities, and in particular relates to a whitening emulsion and a preparation method thereof. Background technique [0002] The skin is the first barrier of the human defense system. If the sebum, sweat, or cosmetics and dust remaining on the skin surface cannot be removed in time, it will cause blockage and inflammation of the hair follicles or sebaceous glands. Acne appears on the surface, if it is not treated in time, the acne will continue to recur, and the deposition of melanin will cause stains, which will eventually lead to a series of skin diseases. [0003] In the existing cosmetics market, there are many kinds of whitening products. These whitening products can be divided into two categories: [0004] 1. Physical whitening products: These products contain a large amount of white or light-colored pigments, such as titanium dioxide, zinc oxide, kaolin, talcum powder, mica, etc., and thes...

Problems solved by technology

[0005] 2. Chemical whitening products, by adding various whitening active ingredients, such as accelerating epidermal renewal, peeling off the melanin that has been formed in the stratum corneum, inhibiting the migration of black bodies from melanocytes to keratinocytes, and inhibiting the activity of tyrosinase The formation of melanin inhibits the formation of melanin by inhibiting the division of melanocytes and reducing the number of melanocytes. Chemical whitening ingredients with high safety performance cannot produce immediate or short-term significant whitening effects

[0006] Physical whitening products, when applied on the skin surface, can have an instant whitening effect and can effectively cover facial blemishes, but after cleaning, the skin will return to its original color, and the whitening effect cannot last long, and it will damage the skin surface after each application. Stimulation; chemical whitening products, under the action of tyrosinase, tyrosine in skin cells is gradually oxidized into dopa and dopaquinone under the influence of various factors in the environment, and dopaquinone undergoes a series of Metabolic reaction, polymerization into 5,6-indole quinone, and finally gradually converted into skin melanin, a chemical whitening product with high safety performance, it can be absorbed by the skin, and then have an effect on melanin, which can achieve a slow whitening effect, but It is also more harmful to the skin, which will cause damage to the skin tissue
