Description

Technical Field

[0001] This application relates to the technical field of scalp care products, and in particular to a compound acid scalp spray and a method for making the same. Background Art

[0002] Modern people are under great living pressure, have intense study, and overuse their brains, which often cause hair loss, or excessive mental stress, all of which will affect the nutrient supply and growth of hair. Environmental pollution will also cause certain damage to our hair. Suspended particles and various pollution sources in the air are easily attached to our hair and scalp. If not cleaned, it will cause the hair to lose luster and be easily broken. The healthy surface layer of hair is composed of a complete group of hair scales and naturally secreted oil to form a protective film for the hair. Excessive washing, dyeing, perming, and sun exposure will all damage this natural protective film, resulting in the loss of cortical moisture, making the hair dry, losing elasticity and softness. Only by performing corresponding hair care can the protective film of the hair be protected and the hair be made healthier.

[0003] For example, Chinese Patent with application number 201710704837.8 discloses a scalp care dry shampoo spray, which includes Sparassis crispa polysaccharide, Alpinia zerumbet essential oil, Morchella esculenta protein, Aloe vera juice, glycerol, corn starch, sodium benzoate, potassium sorbate, polyethylene glycol - 40, etc.

[0004] Regarding the above - mentioned related technologies, the inventor believes that there are the following defects:

[0005] Seborrheic alopecia, oily scalp, etc. are related to multiple reasons. Common scalp care sprays are difficult to improve problems such as scalp micro - ecological disorders, follicular obstruction caused by excessive oil secretion, lack of follicular nutrition, and scalp micro - ecological disorders, so there is room for improvement. Summary of the Invention

[0006] This application provides a compound acid scalp spray and a method for making the same to improve the following technical problems:

[0007] Seborrheic alopecia, oily scalp, etc. are related to multiple reasons.

[0021] In a second aspect, the present application provides a method for preparing the above-mentioned compound acid scalp spray, adopting the following technical solution:

[0022] A method for preparing a compound acid scalp spray includes the following steps:

[0023] (1) Prepare the required weight of raw materials according to the contained percentages;

[0024] (2) Add the prepared raw materials into a vacuum emulsifying pot to obtain a mixed solution, heat the mixed solution to 80 - 85 °C and stir to completely dissolve it to obtain a solution, and keep it warm for 15 - 25 minutes;

[0025] (3) Cool the above solution to 42 - 45 °C through the vacuum emulsifying pot, add lactobionic acid and glycolic acid in sequence, and then keep it warm and stir for 8 - 12 minutes until it is completely uniform;

[0026] (4) After cooling to 39 - 40 °C, keep it warm and stir for 8 - 12 minutes, then cool to 35 °C - 38 °C, and let it stand to obtain the compound acid scalp spray.

[0027] In summary, the working principle and beneficial technical effects of the present application are as follows:

[0028] For the problem of excessive sebum secretion: It is improved by salicylic acid or the compound of salicylic acid and white willow bark extract. Salicylic acid is lipophilic, can clean the excess sebum in the scalp pores, and inhibit the excessive secretion of sebum. It is commonly used in the treatment of seborrheic dermatitis. It can be further combined with white willow bark extract, which contains natural salicin. The compound of azelaic acid, glycolic acid, lactic acid, etc. also has good oil control effect. The combination of multiple compound acids can inhibit sebum secretion through different mechanisms;

[0029] For the problem of scalp microecological disorder: Azelaic acid is an excellent microecological improver, supplemented by lactic acid and glycolic acid to promote microecological renewal. Azelaic acid can inhibit the growth and reproduction of Propionibacterium acnes and Staphylococcus epidermidis, reduce sebum secretion. Azelaic acid derived from wheat combines with glycine, the smallest of the twenty amino acids in the human body (glycine is also rich in natural moisturizing factors), which can help improve the scalp microecology and rebuild the scalp skin barrier;

[0030] For the problem of lack of hair follicle nutrition: Excessive sebum secretion and free fatty acids can stimulate the hair follicle orifice to produce more dandruff and block the hair follicle orifice, resulting in excessive sebum retention. Coupled with the repeated stimulation of free fatty acids, the hair follicle eventually expands and ruptures, and the contents are released into the surrounding tissues to produce an inflammatory reaction, which in turn leads to lack of hair follicle nutrition and blood supply. Compound acids help to remove the accumulation of sebum, thus releasing the hair follicle blockage and improving hair follicle nutrition and blood supply. On the other hand, if necessary, provitamin B5 can be added in an appropriate amount. Provitamin B5 can penetrate deep into the skin and stimulate the growth of epithelial cells, thus directly supplementing the required nutrition for the hair follicles;

[0031] For the problem of scalp oxidative stress disorder: Azelaic acid, salicylic acid, etc. have a compound regulatory effect on oxidative stress, and then improve the scalp oxidative stress problem through multiple pathways. If necessary, compound fruit acid extracts can also be added. Compound fruit acid extracts have a strong antioxidant effect. Taking the oxidative stress level index ROS as an example, compound fruit acid extracts can reduce the ROS level by more than 32% to help improve the problem of scalp oxidative stress disorder;

[0032] For the problem of inflammatory stimulation: Salicylic acid is a common anti-inflammatory ingredient, which can participate in the regulation of cell inflammatory reactions through a wide range of multiple pathways and is widely used in clinical and skincare. Due to its excellent anti-inflammatory effect, azelaic acid has great advantages in the treatment of skin problems such as rosacea. On the scalp and facial skin, salicylic acid and azelaic acid can be further combined with ingredients such as vitamin B5 to reduce the scalp immune response, reduce inflammatory infiltration, delay the destruction and loss of scalp collagen and elastic fibers, and slow down the occurrence of scalp aging;

[0033] In clinical practice, the application of chemical acids on the surface is a common means to improve cell viability. When combined with multiple generations of fruit acids such as glycolic acid and lactic acid, these fruit acids will stimulate skin cells to absorb more moisture, stimulate fibroblast cells to produce more collagen, elastic fibers and mucopolysaccharides, and enhance the collagen content of the skin.

[0034] Starting from the mechanism of scalp oiliness and seborrheic alopecia, this application uses composite functional ingredients to specifically improve excessive sebum secretion, scalp microecological disorders, lack of follicular nutrition, scalp oxidative stress disorders, etc. in a gradient manner according to the mechanism, and comprehensively improves problems such as scalp oiliness. In human efficacy tests, it shows good results of -69.6% in sebum secretion and +68.6% in freshness. Brief Description of the Drawings

[0061] To sum up, the working principle and beneficial technical effects of the present application are as follows:

[0062] Regarding the problem of excessive sebum secretion: It is improved by salicylic acid or the compounding of salicylic acid and white willow bark extract. Salicylic acid is lipophilic and can clean the excess oil in the scalp pores and inhibit the excessive secretion of oil. It is commonly used in the treatment of seborrheic dermatitis. White willow bark extract can be further combined. White willow bark extract contains natural salicin. The compounding of azelaic acid, glycolic acid, lactic acid, etc. also has good oil control effects. The combination of various compound acids can inhibit sebum secretion by compounding from different mechanisms;

[0063] Regarding the problem of scalp microecological disorder: Azelaic acid, as an excellent microecological improver, is supplemented with lactobionic acid and glycolic acid to promote microecological renewal. Azelaic acid can inhibit the growth and reproduction of Propionibacterium acnes and Staphylococcus epidermidis, reduce sebum secretion. Azelaic acid derived from wheat combines with glycine, the smallest of the twenty amino acids in the human body (glycine is also rich in natural moisturizing factors), which can help improve the scalp microecology and rebuild the scalp skin barrier;

[0064] Regarding the problem of lack of follicular nutrition: Excessive sebum secretion and free fatty acids can stimulate the hair follicle orifice to produce more desquamation and block the hair follicle orifice, resulting in excessive sebum retention. Coupled with repeated stimulation by free fatty acids, the hair follicle eventually expands and ruptures, and the contents are released into the surrounding tissues to produce an inflammatory reaction, which in turn leads to a lack of follicular nutrition and blood supply. Compound acids help to remove the accumulation of sebum, thereby relieving hair follicle blockage and improving follicular nutrition and blood supply. On the other hand, if necessary, provitamin B5 can be added in an appropriate amount. Provitamin B5 can penetrate deep into the skin and stimulate the growth of epithelial cells, thereby directly supplementing the required nutrients for the hair follicles;

[0065] Regarding the problem of scalp oxidative stress disorder: Azelaic acid, salicylic acid, etc. have a compound regulatory effect on oxidative stress, and thus improve the scalp oxidative stress problem through multiple pathways. If necessary, compound fruit acid extracts can also be added. Compound fruit acid extracts have a strong antioxidant effect. In terms of the oxidative stress level index ROS, compound fruit acid extracts can reduce the ROS level by more than 32% to help improve the problem of scalp oxidative stress disorder;

[0066] Regarding the problem of inflammatory stimulation: Salicylic acid is a common anti-inflammatory ingredient and can participate in the regulation of cell inflammatory reactions through a wide range of multiple pathways, and is widely used in clinical and skin care. Due to its excellent anti-inflammatory effect, azelaic acid has great advantages in the treatment of skin problems such as rosacea. On the scalp and facial skin, salicylic acid and azelaic acid can further be combined with ingredients such as vitamin B5 to reduce the scalp immune response, reduce inflammatory infiltration, delay the destruction and loss of scalp collagen and elastic fibers, and slow down the occurrence of scalp aging;

[0067] In clinical practice, the topical application of chemical acids is a common means to improve cell vitality. When combined with multi-generation fruit acids such as glycolic acid and lactobionic acid, multi-generation fruit acids will stimulate skin cells to absorb more water, stimulate fibroblast cells to produce more collagen, elastic fibers and mucopolysaccharides, and enhance the skin collagen content;
