Problems solved by technology

[0009] In order to solve the technical defects of current selenium disulfide lotion such as easy discoloration, uneven dispersion, hair sticking, incomplete absorption, and hair damage, the invention provides a selenium disulfide foam and a preparation method thereof. The agent enhances the absorption and utilization of selenium disulfide by the scalp and hair, promotes or enhances the intradermal penetration or delivery of the drug, and then reduces the dosage of selenium disulfide. While having a good anti-dandruff effect, it can achieve hair without discoloration, non-sticking, long-term The use will not damage the hair quality, and the comprehensive effect of the user experience is good

preparation example 1

[0042] Mix selenium disulfide dry powder with a D90 of about 130 μm, water, and glycerin at a mass ratio of 1:3:1, and pulverize it in an ultrafine pulverizer for 30 minutes to finally obtain a selenium disulfide powder with a D90 of about 22 μm.

preparation example 2

[0044] Weigh each component according to proportioning, prepare selenium disulfide foam according to the following steps:

[0045] S1. Put 50% of the total amount of deionized water in the reaction tank of a high-shear mixing emulsifier, heat it to 60°C, add foam support components, foaming agents, and chelating agents under stirring, and stir to dissolve all ingredients. forming a first mixture;

[0046] S2. Dissolving the antioxidant in alcohol, slowly adding the alcohol solution of 10wt% antioxidant, penetration enhancer, phosphatidylserine, and conditioning agent into the first mixture, stirring to dissolve all the ingredients, as the second mixture;

[0047] S3, adding the selenium disulfide micropowder into the second mixture, fully stirring evenly;

[0048] S4. Add an appropriate amount of essence and pH regulator lactic acid, make up deionized water, continue to stir and emulsify for 1 hour, and at the same time cool the temperature of the tank to room temperature to ...

Embodiment 1

[0050] The research of embodiment 1 antioxidant:

[0051] Prepare the selenium disulfide foam agent according to the method of Preparation Example 2, and the composition mass percentage formula of the foam agent is as shown in Table 1 below:

[0052] Table 1 Foam composition

[0053]

[0054] Comparing different types of antioxidants, it is found that the antioxidant effect of butylated hydroxytoluene (BHT) is better than that of vitamin E, and the color of the foam can be satisfied at a lower dosage. After testing, the comparison of different amounts of antioxidants shows that dibutyl hydroxytoluene (BHT) can achieve the color change of the sample in the range of 0.005~10%, and when the amount of dibutyl hydroxytoluene is less than 0.01%, the anti-oxidation cannot be achieved. Effect; more than 10% (0.1% w / w), may cause chronic poisoning, deformity, metabolic disorders and other risks to the human body, so the optimal dosage is 0.03~0.1%.

Abstract

The invention relates to a selenium disulfide foam agent for shampooing and a preparation method thereof. The selenium disulfide foam agent comprises the following raw materials in mass percentage: 0.05-0.5% selenium disulfide micropowder, 5-60% foaming agent , 0.5‑7% conditioning agent, 2‑20% foam proppant, 1.5‑10% penetration enhancer, 0.3‑4% phosphatidylserine, 0.005‑1% antioxidant, 2‑10% propellant, the rest is replenished with water together. Through the selection and proportioning of formula components, the obtained selenium disulfide foam can effectively alleviate and inhibit the symptoms of dandruff and scalp itching, and has excellent sensory experience during use. It is a kind of selenium disulfide shampoo with market competitiveness. hair products.

Description

technical field [0001] The invention relates to the technical field of cosmetics, in particular to a selenium disulfide foam agent for shampooing and a preparation method thereof. Background technique [0002] Selenium sulfide has anti-bacterial, anti-fungal, inhibits the growth of scalp epidermal cells, and has a spore-killing effect on Trichophyton officinalis. Therefore, it is widely used in the care of scalp and hair, and has a good curative effect on symptoms such as dandruff, seborrheic dermatitis, and tinea versicolor. It has been clinically proven that the anti-dandruff effect of selenium disulfide lotion is better than that of ketoconazole. [0003] For selenium disulfide products, most of the products currently on the market are selenium disulfide lotions. There are some flaws and deficiencies. The details are as follows: 1) Based on the almost insoluble characteristics of selenium disulfide in water or organic solvents, it can be clarified that the selenium dis...
