Description

Technical Field

[0001] The present invention relates to the technical field of fine chemicals, and in particular to an anti-hair loss care composition and a preparation method and application thereof. Background Art

[0002] As an integral part of our body structure, hair plays a vital role in our daily lives. Hair not only directly protects the scalp but also acts as a buffer against external forces acting on the scalp, thereby reducing damage and protecting the head. Furthermore, hair has a crucial aesthetic function as well as unique and important social and psychological functions. Traditional Chinese Medicine (TCM) believes that hair is the product of blood, and that the kidneys store essence, the essence of which is found in hair. Hair growth depends on the nourishment of essence and blood. Thick, lustrous hair symbolizes health and creates a positive image. Different hair shapes and conditions create different impressions. Healthy, beautiful hair enhances interpersonal confidence. Conversely, various hair disorders, such as hair loss and thinning hair, can lead to negative emotions like low self-esteem and anxiety, and in severe cases, can even affect social interaction. With changes in living environments and pressures, hair loss and other conditions are becoming increasingly common among young people.

[0003] Traditional anti-hair loss shampoos often contain ginger extract in an attempt to prevent hair loss. However, 6-gingerol, the main active ingredient in ginger, has little effect on promoting hair growth and may even inhibit hair growth. Some traditional anti-hair loss shampoos also add caffeine to their formulas. While caffeine shampoos do have the potential to promote hair growth, the ultimate hair loss prevention effect has not met expectations. Furthermore, some commercially available anti-hair loss shampoos contain sulfate anionic surfactants and use formaldehyde-releasing preservatives such as kasone and DMDM ​​hydantoin. These are highly irritating and, in turn, reduce their effectiveness.

[0004] Other traditional technologies attempt to improve hair loss prevention by adding adenosine to shampoo. However, adenosine easily precipitates during storage and has a strong viscosity-reducing effect in shampoo. Adding polyols to the shampoo further reduces viscosity, while amino acid shampoo systems inherently struggle to thicken. This complicates the use of adenosine in amino acid shampoo products. Consequently, currently available adenosine hair loss prevention shampoos almost all utilize sulfate systems. Sulfate anionic surfactants are inherently irritating to the scalp, resulting in limited hair loss prevention effectiveness. Summary of the Invention

[0005] Based on this, the present invention provides an anti-hair loss care composition, which has a strong anti-hair loss effect, high viscosity and good stability.

[0006] The present invention is achieved through the following technical solutions.

[0007] An anti-hair loss care composition, comprising the following components in percentage by weight:

[0008]

[0009] Wherein, the surfactant is selected from one or more of amino acid surfactants and alkyl glycoside surfactants.

[0010] In one embodiment, the polyol is selected from one or more of glycerol, sorbitol, butylene glycol and propylene glycol.

[0011] In one embodiment, the amino acid surfactant is selected from one or more of cocamidopropyl betaine, sodium lauroyl sarcosinate, sodium lauryl glycol carboxylate and sodium cocoyl methyl taurate;

[0012] The alkyl glucoside surfactant is selected from one or more of decyl glucoside, lauryl glucoside and coconut glucoside.

[0013] In one embodiment, the cationic conditioning agent is selected from one or more of guar hydroxypropyltrimonium chloride and polyquaternium-10.

[0017] In one embodiment, the auxiliary agent satisfies one or more of the following conditions:

[0018] (1) The pH regulator is selected from one or more of citric acid, phosphoric acid, sodium hydroxide and triethanolamine;

[0019] (2) The active ingredient is selected from one or more of adenosine, oxidized keratin, hydrolyzed keratin, Platycladus orientalis leaf extract, Swertia japonica extract, and Morus alba root extract;

[0020] (3) The preservative is selected from one or more of sodium benzoate, phenoxyethanol, ethylhexylglycerin and DMDM ​​hydantoin.

[0021] The present invention also provides a method for preparing the above-mentioned anti-hair loss composition, comprising the following steps:

[0022] Step S1, mixing water, the polyol, the cationic conditioning agent, the surfactant and the chelating agent to prepare a first mixture;

[0023] Step S2, mixing the first mixed material, the surfactant and the pentaerythritol stearate at a temperature of 80° C. to 85° C., and cooling the mixture to 68° C. to 72° C. to prepare a second mixed material;

[0024] Step S3, mixing the second mixed material, the surfactant, the softener and the adenosine, and cooling the mixture to 43° C. to 47° C. to prepare a third mixed material;

[0025] Step S4, mixing the third mixed material with the auxiliary agent;

[0026] Wherein, the mass ratio of the surfactant in step S1, the surfactant in step S2 and the surfactant in step S3 is (5-10):(15-20):1.

[0027] The present invention also provides use of the above-mentioned anti-hair loss care composition in the preparation of shampoo, hair conditioner, hair mask or hair care essential oil.

[0028] Compared with the prior art, the anti-hair loss care composition of the present invention has the following beneficial effects:

Pentaerythritol stearate is selected as a thickener and compounded with adenosine, polyols, amino acid surfactants, alkyl glycoside surfactants and other adjuvants. The composition can gently cleanse the scalp and supplement the scalp with nutrients, thereby strengthening the hair roots and reducing hair loss. At the same time, the composition can also effectively thicken the hair to avoid a significant decrease in viscosity.

[0030] Furthermore, the anti-hair loss care composition of the present invention has good stability, does not require the addition of highly irritating or harmful additives, and does not produce any side effects for users in the long term. DETAILED DESCRIPTION

[0135] Effect verification test

[0136] Effect verification experiments were conducted on the above Examples 1-6 and Comparative Examples 1-2, including physical and chemical tests and anti-shedding tests.

[0137] 1. Physical and chemical test indicators

[0138] (1) Dilute 10 cups of water at 25°C, test with a pH meter, and record the results.

[0139] (2) Viscosity: Model BROOKFIELD, No. 3 rotor, 12 rpm, test and record results;

[0140] The results of physical and chemical tests are shown in Table 3.

[0141] Table 3

[0142] Indicator average pH Viscosity / mPa.s Example 1 5.68 3005 Example 2 5.68 2475 Example 3 5.71 4597 Example 4 5.63 4925 Example 5 5.66 2854 Example 6 5.64 3668 Comparative Example 1 5.69 1768 Comparative Example 2 5.70 2122

[0143] Comparing Examples 4 and 5, we can see that increasing the amount of polyol reduces viscosity; comparing Examples 1 and 2, we can see that increasing the amount of adenosine also reduces viscosity. Comparing the viscosity results of Comparative Examples 1 and 2 with the viscosity of Example 5 demonstrates that PEG-150 pentaerythritol tetrastearate is an irreplaceable thickener in this formulation. A certain ratio of PEG-150 pentaerythritol tetrastearate and citric acid mitigates the severe viscosity-reducing effect caused by the addition of adenosine and polyols, stabilizing the formulation and maintaining certain physical and chemical properties.

[0144] 2. Anti-shedding test

[0145] Subjects should not wash their hair within 48±4 hours before screening and each visit during the trial, and the time without washing hair before each visit should be basically consistent. They should not comb their hair on the day of the visit; they should not have their hair cut within 2 weeks before each visit evaluation during the trial; they should not perform any hair care or hairdressing measures during the trial, nor should they receive any anti-hair loss or hair growth treatments; they should maintain their original lifestyle habits during the trial and avoid large mood swings.

[0146] (1) 140 subjects with mild hair loss were divided into 7 groups, with 20 subjects in each group. Each group was asked to try the shampoo prepared in the above six embodiments for 3 months respectively.

[0147] (2) Two-week washout test: Wash once every two days, using 10 g of the shampoo of Comparative Example 1 each time;

[0148] (3) After the washout period, the subjects entered the experimental group for a ten-week trial: the subjects washed their hair once every two days, using 10 g of the shampoo of Examples 1-6 and Comparative Example 1 each time. Requirement: From the washout period onwards, the subjects were not allowed to wash their hair within 48 hours after using the trial shampoo, and were not allowed to comb their hair after 48 hours;

[0149] (4) Special person combing requirements: specific specifications of combs and specific personnel. Comb from left front to left back, right front to right back, at a constant speed 60 times (30 times on each side);

[0150] (5) Collect and count the fallen hair.

[0151] The anti-shedding test results are shown in Table 4.

[0154] After using shampoo containing adenosine for 3 months, the symptoms of all people with mild hair loss will improve, and the improvement effect will become more obvious as the amount of adenosine added increases.
