Description

oil control convergence composition and preparation method and application thereof

Technical Field

The invention belongs to the field of cosmetics, and particularly relates to an oil-control convergence composition, and a preparation method and application thereof.

Background

Oily skin is a global problem, and consumer survey reports on cosmetic ingredients worldwide have shown that latin americans and asians are most affected by oily skin. Oily skin is more common in men and adolescents, and especially prominent among groups between 15-39 years of age, where the origin of oily skin is the exuberance of sebum secretion. Sebum from healthy skin plays an important role in protecting the skin barrier, protecting skin and hair from abrasion, regulating transepidermal water loss, maintaining skin biofilms, and delivering antioxidants. However, modern life faces more stress and environmental pollution, sebum secretion may be disordered, and then inflammation, oily light, large pores, pore blockage, skin thickening and darkness and other symptoms appear on the skin. In order to suppress excessive sebum secretion and restore the skin to a normal state, it is necessary to develop a cosmetic having an oil control astringent effect. Most of the oil control related cosmetics on the market aim at inhibiting sebum secretion, and although certain instant effect is achieved, the problem is not solved fundamentally, so that the long-acting and lasting effect cannot be achieved.

CN110123736A discloses a composition containing sarcosine, caprylyl glycine, plankton extract, lilac extract and erythritol. The composition has the effects of controlling oil and keeping moisture, but has good instant effect and does not fundamentally solve the problem, and the skin still has the phenomena of inflammation, gloss and coarse pores after being used for a period of time, and the long-acting and lasting effect cannot be achieved.

CN109498480A discloses a whitening oil-control facial cleanser, which comprises the following components in percentage by weight: 6-8% of glycerol, 3-5% of propylene glycol, 25-30% of sodium succinate, 13-18% of sodium lauroyl glutamate, 0.8-1.2% of pearly luster sheet, 1.0-2.0% of thickening agent, 3-5% of cocamidopropyl betaine, 0.3-0.5% of preservative, 0.1-0.2% of essence, 0.3-0.4% of sodium chloride, 1-1.5% of shea butter, 0.8-1.5% of jojoba oil, 1-2% of fomes officinalis extract, 1-2% of papain and the balance of pure water. The invention can only carry out simple grease cleaning and electrolyte shrinkage pore, has limited effect on regulating sebum and can not really achieve the effect of effectively regulating the sebum of skin.

CN106361645A discloses a biological protease acne-removing essence milk. The invention comprises acrylic acid copolymer sodium, protease, butanediol, nicotinamide, lecithin, salicylic acid, silver oxide and a traditional Chinese medicine extract, achieves the purpose of reducing oil secretion by adding the salicylic acid, thereby avoiding excessive secretion of sebaceous glands due to abnormal inflammation, but the method adopts the active substance salicylic acid which belongs to a fruit acid type raw material and has certain skin irritation, so that the method cannot be applied to all people in a large area.

therefore, the composition with the oil control and convergence effects has important significance and wide market prospect in the field of cosmetics.

Test example 1

Haemolysis test of erythrocytes

The erythrocyte hemolysis test is one of the alternatives of the rabbit eye irritation test (Draize test), and the basic principle is to evaluate the damage of chemicals to eye tissue cells by measuring the dissolution amount and denaturation degree of hemoglobin. The RBC test is used internationally for evaluating eye irritation studies on chemicals such as cosmetics and raw materials.

The oil control astringent compositions prepared in examples 1-6 and the compositions prepared in comparative examples 1-10 were subjected to a red blood cell hemolysis test according to the RBC test method and grading standards of the European Alternatives validation center (ECVAM). ECVAM. ECVAM DB-ALM INVITOX Protoco, Red blood cells test system INVITOX No.37 Ispra. Italy ECVAM,1994 ], ECVAM cosmetic products RBC experimental irritation grading criteria are shown in Table 1:

TABLE 1

The results of the experiments on hemolysis of erythrocytes for the oil-controlling astringent compositions prepared in examples 1 to 6 and the compositions prepared in comparative examples 1 to 10 are shown in Table 2, wherein L/D is the ratio of HD50 to DI, wherein HD50 is the sample concentration at which 50% of erythrocytes are hemolyzed, and DI is the protein denaturation index.

TABLE 2

From the results of the erythrocyte hemolysis experiments in table 2, the irritation of the oil-control astringent compositions prepared in examples 1 to 6 of the present invention is classified as non-irritating, which indicates that the oil-control astringent compositions of the present invention are both mild and non-irritating; in the comparative examples, the irritation of the compositions of comparative examples 2, 4, 9 and 10 is classified into micro-irritation, which shows that the five active ingredients are mutually matched, and the toxic and side effects and irritation of the compositions can be obviously reduced after synergistic interaction, so that the aims of reducing the degree of cell hemolysis and protein denaturation are fulfilled.
