Description

Technical Field

[0001] The present invention relates to the field of daily chemical products, and specifically to a children's hair cleaning composition containing camellia extract and its application. Background Art

[0002] The oil on the hair is a substance secreted by the sebaceous glands on the scalp. It helps to protect the hair, keep it moist and shiny. Appropriate sebum can also play an antibacterial and antioxidant role, contributing to the health of the scalp. However, when the hair becomes too oily, a series of problems may occur. Excessive sebum can clog hair follicles, leading to an increase in dandruff and even scalp inflammation. In addition, too much oily hair will make the hair look greasy and dull, affecting the overall image. There are many reasons for excessive hair oiliness. The main factors include environmental factors: pollutants, humidity and temperature changes in the environment can also affect the sebum secretion of the scalp. For example, air pollution can clog pores, resulting in an increase in sebum secretion; a high-temperature and high-humidity environment will accelerate the secretion of sebum. Secondly, there is the genetic factor. Overactive sebaceous glands congenitally can lead to excessive oiliness. To solve these problems, the oil-removing ability of shampoo is particularly important.

[0003] Silicone oil mainly plays a lubricating and smoothing role in shampoo. It can fill the gaps between the hair cuticles, reduce friction, and make the hair look smoother. Since silicone oil is insoluble in water, in order to use it in shampoo, it must be emulsified. The emulsified silicone oil, due to its insolubility in water, forms a milky white suspension. This emulsification process enables the silicone oil to be evenly distributed in the shampoo, providing a smooth effect, but at the same time making the shampoo as a whole appear opaque milky white, which is why most shampoos on the market are milky white.

[0004] Cationic surfactants can reduce the surface tension of liquids, helping to clean, protect and improve the quality of hair. In addition, cationic polymers can also form a film on the hair, playing a lubricating role, reducing the roughness of the hair, being able to improve the scalp and hair, cleaning dirt, oil and chemicals, and at the same time reducing static charges, making the hair softer and smoother. However, cationic polymers may also have some problems. For example, they have a strong adsorption force, are easily attached to the hair strands and difficult to wash off. They not only hinder the entry of nutrients in hair care products into the hair strands, but also adsorb external dust particles, causing dirt accumulation, microbial proliferation, resulting in problems such as dandruff and itchy scalp, and finally leading to blocked scalp pores and even hair loss problems.

[0005] Water-soluble silicone oil in shampoo not only has the same ability as general silicone oil to improve dry hair, increase hair luster, reduce knotting, make it easier to comb, and protect hair quality, but also, due to its hydrophilic nature, it can make a colorless and transparent shampoo. This is different from the milky white shampoo made with general silicone oil. The transparent shampoo has safe ingredients, does not contain any artificial pigments, reduces the addition of chemical substances, thereby reducing potential irritation; it also has better stability, is not prone to oxidation reactions and does not fade or turn yellow, thus extending the product's service life; and the price is more affordable, with relatively lower costs without adding colorants and other blending agents.

[0006] Camellia flower is the plant Camellia japonica of the genus Camellia in the family Theaceae, and its roots and flowers are used as medicine. The roots can be collected throughout the year; the flowers are collected in spring and winter, and dried or baked. Camellia flower extract is obtained by putting the cleaned Camellia flower petals into a blender or grinder to completely crush them, adding an appropriate amount of solution (such as ethanol, water, etc.) to mix, leaving it for a period of time for soaking to dissolve the active ingredients in the petals into the solution, then filtering the solution to obtain Camellia flower extract, and finally concentrating and drying the extract to obtain Camellia flower extract. Camellia flower extract has multiple functions in the cosmetics field, mainly including antioxidant, whitening, moisturizing, cleansing, oil control and anti-acne, soothing and anti-aging effects, etc. Camellia flower extract plays a role in protecting hair, nourishing hair, promoting hair growth, reducing hair loss, and improving scalp health in shampoo. Certain active ingredients in Camellia flower extract can stimulate hair follicle growth, help promote hair growth, and reduce hair loss. Using Camellia flower extract in shampoo can also balance the oil secretion of the scalp, reduce scalp inflammation, thus improving scalp health and reducing dandruff production.

[0007] Grape fruit extract has an inhibitory effect on caspase-8. Caspase is the core component leading to apoptosis, so its inhibition means not only extending the life of cells but also enhancing skin activity; it has the effect of eliminating free radicals, inhibiting collagenase, and inhibiting the production of nitrogen oxides, showing the ability to inhibit aging in many aspects; when the concentration is 1%, it can inhibit melanin production; it has a shrinking and astringent effect on pore diameter and has a firming effect on the skin. Used in shampoo, it can reduce scalp oiliness and keep hair fresh.

[0008] Publication number CN 10151133A (P06 - 767) provides a skin or hair cleansing composition, which has excellent foaming properties and a good feel from cleansing to drying. The composition provides many preferences for various anionic surfactants, non-ionic surfactants, and amphoteric surfactants. According to the selection of the provided surfactants, excellent foaming properties and a good feel from cleansing to drying can be achieved.

[0009] In the research on removing oil from shampoo, cationic surfactants are mostly used to remove organic substances such as oil and dirt, and at the same time, they can also destroy the cell membrane structure of microorganisms, thus achieving the effect of sterilization. However, the foaming ability of cationic surfactants is limited. In addition, the cationic polymers in shampoo can cause hair breakage and hair loss problems, and at the same time, dandruff is generated, and allergic reactions occur on the scalp, such as scalp itching, redness, etc. There is currently little research on the relevant data of transparent shampoo that uses natural and safe plant extracts to nourish and protect the scalp and hair, while achieving the effect of removing oil and dirt, and the conditioning ingredients do not contain cationic polymers and cationic surfactants.

[0052] 3. Test method: Examine the two eyes of the test animals within 24 hours before the test. Gently separate the right eyelid of the animal, and directly drop 0.1 mL of the test substance into the conjunctival sac. Passively close the eyelids for 1 s. The left eye is not treated as a self-control. After instillation, rinse with normal saline at a sufficient flow rate that is fast but does not cause eye damage for 30 s after 30 s. Examine the eyes with a slit lamp and sodium fluorescein (after 24 h) at 1 h, 24 h, 48 h, 72 h, 4 d, and 7 d after instillation. If no irritation reaction occurs within 72 h, the observation can be terminated. If there is still an eye irritation reaction within 7 d, the observation can be continued until 21 d.
