Abstract
Description
Technical Field
[0001] This invention relates to the field of hair perming technology, and in particular to a hair perming composition based on thermosensitive control and its preparation method. Background Technology
[0002] Current hair perming techniques are mainly divided into two categories: cold perms and hot perms. Cold perms involve applying chemicals after curling the hair rods or applying chemicals while curling, using low-temperature external heat. This method is fast and softens and shapes the hair simultaneously, but it lacks hydrogen bond recombination, making it prone to wet curls and dry straightening, resulting in frizz and poor shine after the perm. Hot perms require applying different pH solutions to different sections of hair based on its type. After softening, the hair is rinsed and curled, then dried at 100-130℃ to set the style. This method can achieve hydrogen bond recombination and is suitable for medium to long wavy hair, but it is more complex and slower.
[0003] In traditional perming concepts, most hairdressers believe that opening the hair cuticle and breaking disulfide bonds is the process of the softening agent reaction during perming. However, in the microscopic structure of hair, hydrogen bonds, salt bonds, and disulfide bonds are not completely isolated, but interact to form a strong molecular network. Therefore, when the softening agent is applied to the hair, during the process of the alkali agent cutting and expanding the hair cuticle, a large number of disulfide bonds in the cuticle are first cut and destroyed, resulting in a softened state that is soft on the outside and hard on the inside. This leads to insufficient elasticity in the permed curls, or severe damage to the hair cuticle, resulting in frizz and difficulty in styling at home. Furthermore, the softening reaction cannot be dynamically controlled and relies entirely on the hairdresser's experience. Misjudgment can easily cause hair damage, making it difficult to standardize the effect and adapt to different hair types, such as healthy roots and damaged ends, resulting in uneven softening and inconsistent curls.
[0004] In addition, existing hot perming methods are clearly insufficient for dealing with fine and damaged hair. When the hair is softened, the disulfide bonds are broken, and the hair loses its natural texture and becomes noticeably softer, making it difficult to support curls. If the softening is not done properly, it is difficult to perm. If the softening is done properly, the hair will lose its natural firmness and texture. Summary of the Invention
[0005] The purpose of this invention is to provide a perming composition based on thermosensitive regulation and its preparation method. Through the synergistic effect of thermosensitive regulation and cysteine compound reduction system, it combines the advantages of cold perming operation and simplifies the judgment and operation process of softening.

[0011] The beneficial effects of the thermosensitive alkali-based perming composition and its preparation method disclosed in this invention are as follows: Ammonium carbonate is introduced into the perming composition as a thermosensitive alkali source. Utilizing ammonium carbonate thermosensitive alkali regulation technology, precise reaction control of activation at room temperature and deactivation at high temperature is achieved. Furthermore, at high temperatures, ammonium carbonate decomposes and escapes, reducing residual alkali irritation after perming. Simultaneously, the pH of the system decreases, and the reducing buffer phase automatically deactivates, preventing excessive softening, limpness, and breakage of the hair strands. This facilitates the orderly recombination and shaping of hydrogen bonds in the hair strands. The use of a cysteine and cysteamine complex reduction system forms a synergistic molecular enhancement effect, ensuring hair softening efficiency while solving the problem of uneven softening. Moreover, cysteine and cysteamine, along with... The decomposition products of ammonium carbonate form a hydrogen bond network, making the thermosensitive control process more stable, widening the perming operation window, and making it easier for hairdressers to operate. At the same time, it contains active repair phase and nourishing repair phase. During the heating process, repairing ingredients such as ceramides encapsulated in liposomes are slowly released, repairing the hair cuticle while perming and shaping, and also improving heat conduction, providing a certain heat retention effect, making the hair strands more evenly heated, which is conducive to the precise recombination of disulfide bonds during the hydrogen bond recombination process, enhancing elasticity, achieving the effect of becoming curlier as it dries, and improving frizz and dryness of hair. It combines the advantages of cold perming and hot perming, softening and shaping are carried out simultaneously, which meets the requirements of healthy, fast, gentle and simple perming results.

[0014] The present invention will be further described and illustrated below with reference to specific embodiments and the accompanying drawings: Please refer to Figure 1 A heat-sensitive perming composition, comprising the following components in 100 parts by total weight: The aqueous phase comprises 0.05-0.2 parts by weight of disodium EDTA, 1-3 parts by weight of urea, 3-8 parts by weight of glycerol, 0.05-0.2 parts by weight of methylparaben, 0.05-0.2 parts by weight of propylparaben, and 0.2-0.5 parts by weight of phenoxyethanol. The reducing buffer phase comprises 3-8 parts by weight of cysteine hydrochloride, 0.8-3.5 parts by weight of cysteamine, 1-2 parts by weight of sodium bicarbonate, 1.5-4 parts by weight of ammonium carbonate, and 1-2.5 parts by weight of ammonia, with a pH of 8.0-8.5. The emulsified oil phase comprises 3-8 parts by weight of caprylic / capric triglyceride, 1-3 parts by weight of polydimethylsiloxane alcohol, 2-3 parts by weight of sodium lauroyl glutamate, 1-2 parts by weight of cocamidopropyl betaine and 0.5-1.5 parts by weight of PEG-40 hydrogenated castor oil. The active repair phase comprises 0.5-1.5 parts by weight of phosphatidylcholine, 0.3-0.8 parts by weight of hydrogenated lecithin, 0.2-0.8 parts by weight of ceramide, 0.1-0.3 parts by weight of tocopherol, 0.05-0.2 parts by weight of ascorbate palmitate, 0.3-0.8 parts by weight of ethoxydiethylene glycol, 0.2-0.5 parts by weight of p-hydroxyacetophenone, and 0.2-0.5 parts by weight of 1,2-hexanediol; The maintenance and repair phase includes 0.5-2.5 parts by weight of hydrolyzed keratin, 0.5-1.5 parts by weight of arginine, 0.005-0.01 parts by weight of methylisothiazolinone, and 4.35-12.15 parts by weight of daily fragrance. The rest is deionized water.
[0015] Depending on the hair type of different individuals, the following adjustments can be made: For normal hair: increase cysteine to 1-2 parts, cysteine hydrochloride to 5-8 parts, ammonium carbonate to 2-3 parts, ceramide to 0.2-0.5 parts, hydrolyzed keratin to 0.5-1.5 parts, and adjust pH to 8.0-8.5; To combat hair damage: Increase cysteine to 2.5-3.5 parts, cysteine hydrochloride to 7-8 parts, ammonium carbonate to 3.5-4.0 parts, ceramide to 0.2-0.5 parts, hydrolyzed keratin to 0.5-1.5 parts, and adjust pH to 8.0-8.5; For damaged / fine hair: reduce cysteine to 0.8-1.2 parts, cysteine hydrochloride to 3-4 parts, ammonium carbonate to 1.5-2.0 parts, ceramide to 0.5-0.8 parts, hydrolyzed keratin to 1.5-2.5 parts, and adjust pH to 7.8-8.0.
[0016] The mass concentration of the ammonia solution mentioned above is 25%.
[0017] refer to Figure 2 Utilizing a thermosensitive control mechanism: with ammonium carbonate as the core thermosensitive alkali source, the pH of the system and the activity of the reducing agent can be dynamically and precisely controlled according to the temperature gradient. In the room temperature and low temperature range of 20-60℃, ammonium carbonate is stable, the system maintains a suitable weakly alkaline environment for perming, the reducing agent is fully activated, and the hair strand structure can be stably opened and uniform softening can be completed. When the temperature is raised to 60-95℃, ammonium carbonate gradually decomposes, the pH of the system decreases, the activity of the reducing agent gradually decreases, and the perming reaction is prevented from continuing to be excessive. When the temperature reaches 95℃ or above, ammonium carbonate completely decomposes, the system approaches neutrality, the reducing agent essentially stops working, and the hair softening reaction is completely terminated.
[0018] This temperature control linkage mechanism can precisely control the perming reaction process, eliminating problems such as excessive softening, breakage, and limpness of hair from the root. At the same time, ammonium carbonate decomposes at high temperature without leaving any solid residue, achieving perming without alkali residue, greatly improving the safety and stability of perming, and effectively widening the tolerance window for perming operations.
[0019] Simultaneously, a complex synergistic mechanism is utilized: a dual reduction synergistic system combining cysteine and cysteine is adopted to construct a layered and controllable hair softening reaction mechanism.
[0020] Among them, small molecule cysteine has excellent penetration ability, which can penetrate deep into the hair cortex and efficiently cut disulfide bonds to achieve deep softening; cysteine can form hydrogen bonds with hair disulfide bonds through amino groups to anchor, assisting thiol groups to accurately act on target sites, improving reaction accuracy, ensuring deep softening effect on hair, solving the problems of uneven softening and insufficient penetration in traditional perming, and buffering the reaction rate to avoid hair damage caused by excessively fast local reactions, making the overall perming reaction more uniform, gentle and stable.
[0021] Ammonium carbonate is introduced as a thermosensitive alkali source into the perming composition. Utilizing ammonium carbonate thermosensitive alkali regulation technology, precise reaction control is achieved for activation at room temperature and deactivation at high temperatures. Furthermore, at high temperatures, ammonium carbonate decomposes and escapes, reducing residual alkali irritation after perming. Simultaneously, the system pH decreases, and the reducing buffer phase automatically deactivates, preventing damage to the hair cuticle by the softening agent during prolonged softening reactions. This preserves the hair's natural hardness and texture, preventing excessive softening, limpness, and breakage. It also promotes the orderly recombination and styling of hydrogen bonds in the hair. A cysteine and cysteine complex reduction system is employed to create a synergistic molecular enhancement effect, ensuring efficient softening while addressing uneven softening. Moreover, cysteine and... Cysteine forms a hydrogen bond network with the decomposition products of ammonium carbonate, making the heat-sensitive control process more stable, widening the perming operation window, and making it easier for hairdressers to operate. At the same time, it contains active repair phase and nourishing repair phase. During the heating process, repairing ingredients such as ceramides encapsulated in liposomes are slowly released, repairing the hair cuticle while perming and shaping, and also improving heat conduction, providing a certain heat retention effect, making the hair strands more evenly heated, which is conducive to the precise recombination of disulfide bonds during the hydrogen bond recombination process, enhancing elasticity, achieving the effect of becoming curlier as it dries, and improving frizz and dryness of hair. It combines the advantages of cold perming and hot perming, softening and shaping are carried out simultaneously, which meets the requirements of healthy, fast, gentle and simple perming results.
[0022] A method for preparing the above-mentioned hair perming composition includes the following steps: S1. Add disodium EDTA, urea, glycerin, methylparaben, propylparaben, and phenoxyethanol sequentially to deionized water, stir and heat to 70-75℃, keep for 5-10 minutes until completely dissolved and transparent, and keep warm for later use. S2, phosphatidylcholine, hydrogenated lecithin, ceramide, tocopherol, ascorbate palmitate, ethoxydiethylene glycol, p-hydroxyacetophenone, and 1,2-hexanediol are heated to 70-75°C while stirring until completely dissolved. S3. Add the solution obtained in S1 to the solution dissolved in S2, and homogenize it with a high-speed homogenizer at 5000-8000 rpm for 3-5 minutes to form a milky white emulsion with a particle size of less than 100 nm, and gradually stir and cool it down to below 40°C. S4, after cooling, add cysteine hydrochloride, cysteamine and sodium bicarbonate to the emulsion of S3, stir until completely dissolved, and the solution pH is 5-6; S5, caprylic / capric triglyceride, polydimethylsiloxane alcohol, sodium lauroyl glutamate, cocamidopropyl betaine and PEG-40 hydrogenated castor oil are stirred and mixed, and then the mixed solution is added to the solution obtained in S4.

Add ammonium carbonate powder to the solution obtained in S6, stir to dissolve, and use ammonia water to control the pH at 8.0-8.2. S8.

[0023] The hair perming composition of the present invention can be used alone as a hair perming agent or in combination with a thioglycolic acid hair perming agent.
[0024] How to use it alone as a hair perming agent: Apply the perming composition evenly to wet hair. The dosage can be controlled by applying it in sections according to the hair type. Perform bar winding, selecting the appropriate bar size as needed; Heat the product at a temperature range of 60-80℃ for 5-10 minutes to expand the scales. Spray water to keep it moist, and let it sit for 5 minutes to allow it to penetrate. Continue heating at 80-100 degrees Celsius for about 10-15 minutes to decompose ammonium carbonate, slow down the reaction automatically, and allow for penetration and shaping, as well as disulfide bond recombination. Further increase the heating temperature to 120-130 degrees Celsius to allow hydrogen bonds to be rebuilt in an orderly manner in a coiled state; Then apply a setting agent and let it sit for 10-15 minutes to fix the curl. Finally, the bumper was removed, the car was rinsed, and the car was styled.
[0025] Use in conjunction with thioglycolic acid perming agents (synergistic mode) Use diluted thioglycolic acid perm solution to soften healthy hair for 30 minutes.
[0026] After 30 minutes, coarse and stiff hair strands are in a stiff state, while fine and soft hair strands may be slightly elastic. However, the hair color shows obvious discoloration, indicating that the hair cuticles have been opened in advance, creating a channel for the perming composition to penetrate into the sebum layer, allowing cysteine to precisely act on the disulfide bonds in the sebum layer. Use shampoo to thoroughly wash away the softener and then condition your hair; Then roll up the roller, applying the coating evenly while rolling. First, heat at a temperature of 60-80℃ for 5-10 minutes, then heat at 120-130℃ for 10-20 minutes to decompose ammonium carbonate; the reaction is controllable.
[0027] After it cools naturally, apply a setting agent to fix the curl.
[0028] The hair care ingredients in this invention can effectively neutralize the alkaline components of hair, thus achieving the effects of hair care and curl enhancement.
[0029] Summary table comparing the beneficial effects of this invention with those of thioglycolic acid-based and cysteine-based hair perming agents. This invention provides a heat-sensitive controlled perming composition and its preparation method. Ammonium carbonate is introduced into the perming composition as a heat-sensitive alkali source. Utilizing ammonium carbonate heat-sensitive alkali control technology, precise reaction control is achieved for activation at room temperature and deactivation at high temperature. Furthermore, at high temperatures, ammonium carbonate decomposes and escapes, reducing residual alkali irritation after perming. Simultaneously, the pH of the system decreases, and the reducing buffer phase automatically deactivates, preventing damage to the hair cuticle by the softening agent during prolonged softening reactions. This preserves the hair's natural hardness and texture, preventing excessive softening, limpness, and breakage. It also promotes the orderly recombination and styling of hydrogen bonds in the hair strands. A cysteine and cysteine complex reducing system is used to form a synergistic molecular enhancement effect, ensuring softening efficiency while solving the softening problem. The unevenness of the perm process is addressed by the formation of a hydrogen bond network between cysteine and cysteine and the decomposition products of ammonium carbonate, resulting in a more stable heat-sensitive control process. This widens the perming operation window, making it easier for hairdressers to operate. It also incorporates active and nourishing repair phases. During heating, liposome-encapsulated repairing ingredients such as ceramides are slowly released, repairing the hair cuticle while shaping the hair. This also improves heat conduction, providing a certain degree of insulation and ensuring more even heating of the hair. This facilitates the precise recombination of disulfide bonds during hydrogen bond recombination, enhancing elasticity and achieving a curlier, drier effect. It improves frizz and dryness, combining the advantages of both cold and hot perms. Softening and shaping occur simultaneously, resulting in a healthy, fast, gentle, and simple perming experience.
