Description

Organic zinc compound oil-control anti-dandruff shampoo and preparation method thereof
Technical Field
The invention relates to the technical field of the lightening industry, in particular to an organic zinc compound oil-controlling and anti-dandruff shampoo and a preparation method thereof.
Background
Similar to the skin of other parts of the human body, the scalp is also covered with an oil film, the main component of which is sebum. Sebum is composed of sebaceous glands, sweat gland secretions and keratinocyte disintegrates, and is closely related to skin moisture, pH value and skin flora. The normally secreted oil has the functions of moistening skin, resisting infection, blocking, etc. However, excessive secretion of oil causes the acid-base balance to be disrupted, and dysbacteriosis to cause many skin problems such as Seborrheic Dermatitis (SD), dandruff, alopecia, and the like. One of the causes of dandruff is hypersecretion of oil and fat, in addition to malassezia bacteria. The malassezia is fed by grease, metabolites can stimulate the scalp to generate dandruff, excessive grease can promote the growth of the malassezia and can also generate more products which stimulate the scalp, so that the problem of excessive grease of the scalp is solved, and the scalp dandruff can be greatly relieved. Statistical data show that about 50% of adults have dandruff trouble, so that the shampoo for controlling oil and removing dandruff of the scalp has great market demand.
There are many factors that affect scalp oil secretion, including: 1. androgen levels, the sebaceous gland is a target organ for androgens, testosterone increases sebaceous gland volume and secretion; 2. skin surface flora, such as malassezia can decompose triglyceride and saturated fatty acid in sebum, and also influence the oil secretion rate; 3. age, sex, season, etc.
At present, most of oil control products on the market are designed aiming at androgen, and single oil control components are mostly used, so the problems of poor oil control effect, poor effect persistence and the like exist, and the drug resistance is easy to generate.
In view of this, the invention is particularly proposed.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be described in detail below. It is to be understood that the described embodiments are merely exemplary of the invention, and not restrictive of the full scope of the invention. All other embodiments, which can be derived by a person skilled in the art from the examples given herein without any inventive step, are within the scope of the present invention.
Aiming at the problems that the oil control product on the market at present mostly uses a single oil control component, the oil control effect is poor, the effect persistence is poor and the like, the shampoo disclosed by the invention is compounded with three oil control functional components, including zinc lactate, zinc yeast and Zinc Pyrithione (ZPT), and researches show that the zinc has a good oil control effect. The oil control mechanism of zinc includes: 1) inhibiting 5 alpha-reductase which converts testosterone to dihydrotestosterone, thereby reducing stimulation of sebaceous gland production by dihydrotestosterone; 2) inhibiting bacterial lipase on the skin, thereby inhibiting the bacteria from catalyzing the breakdown of triglycerides in sebum into free fatty acids.
The zinc added into the cosmetic can be divided into organic zinc and inorganic zinc (such as zinc sulfate and zinc chloride), and the inorganic zinc has abundant resources and lower price than the organic zinc. But the organic zinc has less irritation, high chemical stability and high bioavailability compared with inorganic zinc, and can be absorbed and utilized by cells of a human body more.
The zinc lactate, the yeast zinc and the ZPT all belong to organic zinc. Besides providing zinc ions, ZPT is commonly used in washing and caring products, is low in price but limited in bioavailability, so that yeast zinc and zinc lactate with high bioavailability are compounded on the basis of selecting ZPT, and the oil control effect is enhanced after compounding. Zinc Pyrithione (ZPT) can also inhibit malassezia so as to achieve the function of removing dandruff, so that the compounded active substance has the efficacy of controlling oil and removing dandruff. The yeast zinc and the zinc lactate contain yeast extract and lactic acid, and can play a role in moisturizing and repairing scalp barriers and relieve discomfort caused by excessive scalp grease secretion. The following are details of the three raw materials:
zinc lactate under the trade name
Figure BDA0002816403650000061
Purchased from Corbion corporation. Has effects in controlling oil, relieving itching, and inhibiting bacteria. In addition to providing zinc, lactic acid is also an important component of natural skin moisturizing factor (NMF), and can provide additional moisturizing effects.
Yeast zinc, available under the trade name Yeast essence Z20, was purchased from Angel Yeast Inc. The Angel zinc-rich yeast extract is obtained by enriching inorganic zinc element with yeast, and combining zinc with protein and amino acid in yeast, so that it has the following advantages: the combined form of zinc and small molecule polypeptide is easier to be absorbed through skin; the product is mild, and the irritation of inorganic zinc to the skin is reduced; the yeast fermentation metabolite also has good repairing effect on skin.
Zinc Pyrithione (ZPT), marketed as Zinc OmadineTM by Lonza, FDA's validation record (1991) allows ZPT to be used in the treatment of dandruff and seborrheic dermatitis. Dandruff occurs for three reasons: the first is malassezia, the second is grease secretion, and the third is individual susceptibility. ZPT has good antibacterial effect, and can inhibit growth of malassezia, an important fungus in dandruff occurrence.
By compounding the three zinc-rich organic active substances, the grease secretion can be more effectively inhibited compared with the single component, and the compounding and synergism effects are achieved. And ZPT can inhibit malassezia so as to inhibit dandruff, and in addition, three compounded components can synthesize other beneficial effects of a single component on skin, so that the oil control and dandruff removal effects are achieved, and the skin is more friendly. According to the experimental result, if too much compound zinc component is added, the oil control and anti-dandruff effect is rather reduced, so the selected oil control components are added with 0.01-3 parts of yeast zinc, 0.1-2 parts of Zinc Pyrithione (ZPT) and 0.01-0.5 part of zinc lactate. The purpose of adding zinc sulfate/zinc chloride on the basis is to prevent the ZPT from meeting trace iron ions in water to change the material body into grey or grey purple to influence the appearance of the product.
In addition, the invention achieves the purpose of enhancing the deposition of three zinc-rich organic active substances by compounding the anion and cation surfactants. Specifically, the sulfate shampoo is compounded with sodium laureth sulfate and disodium cocoyl glutamate with a dicarboxy end, so that the flocculation effect of the shampoo and a cationic polymer is enhanced, more oil control active ingredients are wrapped, and a more lasting oil control effect is achieved. In the case of the amino acid shampoo, the adopted main surfactant is disodium cocoyl glutamate, and the substance can increase the flocculation effect by itself.

Oil control capability test of shampoo
90 volunteers were recruited as subjects between the ages of 20 and 40. All volunteers were divided into 9 groups of 10 persons each, and the shampoos prepared in examples 1-9 were used for each group. Subjects did not wash their hair 24 hours prior to testing and baseline values were tested. After shampooing with the shampoo according to each example on site, the scalp (head top) oil value was measured at T0 instant, T2h, T4h, T6h, T8h, T20h, T24h and T26h, respectively, and then the oil control time of each group of subjects was averaged to obtain the oil control time for each example.
The oil control efficiency of the product is evaluated by comparing the change of indexes before and after use by adopting random and parallel control research, measuring the scalp oil content through an instrument Meibometer MB560 and evaluating a method of a researcher. The oil control time is the time for recovering the oil value of the scalp of a subject before hair washing, and the longer the oil control time is, the better the oil control effect of the product is.
Dandruff control test for shampoo
In addition, 90 volunteers with obvious dandruff were recruited as subjects, and all volunteers were divided into 9 groups of 10 persons each, and the shampoos prepared in examples 1 to 9 were used for each group. The head of all the subjects has excessive compound dandruff such as flaky white scale. All shampoo, hair care and daily chemical products with the anti-dandruff effect are stopped for the first two weeks. The subjects used the shampoo prepared in the above examples at least 3 times per week, and evaluated by a professional qualified dermatologist. Dandruff status was assessed prior to shampoo use and at 28 days of use, and the dandruff scores for each group of subjects were averaged to give a dandruff score for each example.
The clinical evaluation method comprises the following steps: the method adopts a ten-grade grading method of adhesive scurf, namely, grade 0 indicates no scurf, grade 1-2 indicates small powdery grey coarse scale, grade 3-4 indicates small to medium-sized chips, grade 5-6 indicates large and thin chips loosely connected with the scalp, grade 7-8 indicates large adhesive chips, and grade 9-10 indicates white to yellow thicker scales tightly attached to the scalp.
The results of the tests for oil control and anti-dandruff ability of the shampoo are shown in table 1.
Among them, example 1 is a blank control group without the tri-zinc oil control active ingredient, and it can be seen that the oil control time is shortest and the dandruff score is highest.
Example 2 the tri-zinc active ingredient was added in the optimum ratio, which has the best oil control and anti-dandruff effect.
The other raw materials of example 3 were the same as those of example 2 except that guar hydroxypropyltrimonium chloride was replaced with polyquaternium-10, which shows a great decrease in oil-controlling and anti-dandruff abilities, indicating that guar hydroxypropyltrimonium chloride is preferable as the cationic surfactant.
Example 4 without any cationic surfactant, the oil-controlling and anti-dandruff ability is further reduced compared with example 3, which shows that the selection of proper cationic surfactant contributes to the oil-controlling and anti-dandruff effect of the shampoo besides the organic zinc oil-controlling active ingredient.
Example 5 did not add yeast zinc compared to example 2, example 6 did not add zinc lactate compared to example 2, and example 7 did not add zinc pyrithione compared to example 2. Wherein the oil control time of examples 5 and 6 decreased greatly, and the dandruff score of example 7 increased greatly, indicating that yeast zinc and zinc lactate have a greater effect on scalp oil control, while zinc pyrithione contributed greatly to dandruff control.
Example 8 has higher concentration of tri-zinc than example 2, and example 9 has lower concentration of tri-zinc than example 2, and the oil control and anti-dandruff capability of the composition is reduced. The adding amount of the three-zinc oil control active ingredients is controlled within a proper range, so that better effects can be exerted.
Orthogonal experiment of sulfate shampoo
Examples 1-1 to 1-9 were designed by changing the amounts of yeast zinc, zinc lactate and zinc pyrithione in shampoo, while keeping other materials unchanged based on example 1, in order to design an orthogonal experiment to obtain the optimum amount of tri-zinc oil-control active ingredients. 80 volunteers were randomly divided into 8 groups, and oil control ability test was performed by the same test method as in the sulfate type shampoo, and the oil control time of examples 1-1 to 1-9 was recorded. The specific setup is shown in table 2, and the results of the orthogonal experiments are shown in table 3.
TABLE 2
Figure BDA0002816403650000111
TABLE 3
Zinc pyrithione Yeast zinc Zinc lactate
k1 13.80 16.73 17.80
k2 13.60 12.27 11.20
k3 11.87 10.27 10.27
K1 41.4 50.2 53.4
K2 40.8 36.8 33.6
K3 35.6 30.8 30.8
R (great difference) 5.80 19.40 22.60
In Table 3, K1 is taken as an example of 13.80, which represents the average value of the oil control time when the amount of zinc pyrithione is 0.1, and K1 is the sum of the oil control time; taking k2 as an example of 13.60, the value represents the average value of the oil time when the zinc pyrithione addition amount is 1, and so on. The R (range) value is the sum of the maximum oil control time minus the minimum oil control time of the corresponding influence factors, and the larger the R value is, the larger the influence factor has larger influence on the oil control time.
From the oil-controlling time of Table 2, it is understood that the oil-controlling time is the maximum when the amount ratio of zinc pyrithione, zinc yeast and zinc lactate is 0.1:0.5: 0.1. From the R value, it can be seen that the effect of zinc lactate and zinc yeast on oil control time was greater than that of zinc pyrithione in the above test.
