Problems solved by technology

At present, some perm products on the market use the compound formula of cysteamine and thioglycolic acid, so that the softening time of the product is about 20-30% shorter than that of the thioglycolic acid formula when the pH value of the product is about 8.5, and the curl of the hair is also lower than that of the thioglycolic acid formula. The formula of thioglycolic acid is stronger, and the hair damage is significantly reduced, but the specific bad smell produced by residual cysteamine in the hair after perm

Embodiment 1

[0007] Preparation of the first dose of cold perm essence (normal hair quality)

[0008] 27 grams of thioglycolic acid, 3 grams of etidylic acid, 70 grams of cysteamine hydrochloride, 55 grams of monoethanolamine, 30 grams of polyquaternium-22, and 800 grams of deionized water were heated and stirred to dissolve, and were dissolved with ammonia (20 %) adjust the pH to 8.5, lower the temperature to 40°C, and slowly add 20 grams of PEG-40 hydrogenated castor oil, 1 gram of tangerine peel oil, 1 gram of Wenzhou satsuma fruit oil, 1 gram of citrus leaf oil, and essence while stirring. 1 g, add deionized water until the first dose weighs 1000 g. Stirring was continued for 10 minutes, and it was terminated.

[0009] Preparation of the second dose of cold perm essence (normal hair quality)

[0010] Add 4 grams of etidyl diphosphate, 2 grams of disodium hydrogen phosphate, 20 grams of lauryl amidopropyl betaine, 10 grams of oleth-20, 30 grams of polyquaternium-22, styrene / VA copolym...

Embodiment 2

[0012] Preparation of the first dose of cold perm essence (anti-hair quality)

[0013] 30 grams of thioglycolic acid, 3 grams of etidylphosphate, 85 grams of cysteamine hydrochloride, 55 grams of monoethanolamine, 30 grams of polyquaternium-22, and 800 grams of deionized water were heated and stirred to dissolve, and were dissolved with ammonia (20 %) adjust the pH to 8.5, lower the temperature to 40°C, and slowly add 20 grams of PEG-40 hydrogenated castor oil, 1 gram of tangerine peel oil, 1 gram of Wenzhou satsuma fruit oil, 1 gram of citrus leaf oil, and essence while stirring. 1 g, add deionized water until the first dose weighs 1000 g. Stirring was continued for 10 minutes, and it was terminated.

[0014] Preparation of the second dose of cold perm essence (anti-hair quality)

[0015] The same as the preparation of the second dose of cold perm essence (normal hair quality) in Example 1.

Embodiment 3

[0017] Preparation of the first dose of cold perm essence (damaged hair)

[0018] 25 grams of thioglycolic acid, 3 grams of etidylphosphate, 52 grams of cysteamine hydrochloride, 45 grams of monoethanolamine, 30 grams of polyquaternium-22, and 800 grams of deionized water were heated and stirred for dissolution, and were dissolved with ammonia (20 %) adjust the pH to 8.5, lower the temperature to 40°C, and slowly add 20 grams of PEG-40 hydrogenated castor oil, 1 gram of tangerine peel oil, 1 gram of Wenzhou satsuma fruit oil, 1 gram of citrus leaf oil, and essence while stirring. 1 g, add deionized water until the first dose weighs 1000 g. Stirring was continued for 10 minutes, and it was terminated.

[0019] Preparation of the second dose of cold perm essence (damaged hair)

[0020] With the preparation of the second agent of cold perm essence (normal hair quality) of embodiment 1

Abstract

The invention relates to a hair-waving agent, in particular to a hair-waving agent, which contains cysteamine or a salt of the cysteamine and contains at least one of peel oil of CITRUS TANGERINA, peel oil of CITRUS UNSHIU and leaf oil of CITRUS RETICULATA. After the hair-waving agent is used, no peculiar smell is generated by the cysteamine; the waved hairs are good in texture; and a hair style is well kept.

Description

technical field [0001] The present invention relates to a hair perm agent, and more specifically relates to a hair perm agent containing cysteamine or its salts, which has no specific bad smell produced by cysteamine after use, has a good texture after perming, and is also excellent in hair style retention. Background technique [0002] There are mainly two types of perm products, one is composed of the first agent containing mercapto compound and the second agent containing oxidizing agent, and the other is composed of the first agent containing mercapto compound and the second agent containing oxidizing agent and hair care ingredients Composition of the 3rd dose. Perm products mainly use thioglycolic acid as the main reducing agent. Although thioglycolic acid has a strong reducing ability, it also causes greater damage to hair and has a greater odor. Although cysteamine has a weaker reducing ability than thioglycolic acid, its damage to hair is less than that of thioglyco...
