JPH06293621A - Perming solution - Google Patents

Abstract

PURPOSE:To obtain a perming solution hardly damaging hair only by the addition of a small amount of a specific betaine and having extremely good touch after using by including the specific betaine as an active ingredient. CONSTITUTION:This perming solution contains a betaine expressed by the formula (another name: trimethylglycine, glycine betaine or alkyldimethyl betaine) as an active ingredient. The betaine has excellent hair protecting action and can improve handle after using. The betaine is contained in an amount of 0.05-20 pts.wt., preferably 2-6 pts.wt. The perming solution may contain, e.g. thioglycol acid or its salt, an alkali such as ammonia, a surfactant such as stearyl chloride trimethylammonium salt, a stabilizer such as ethylene diamine tetraacetate.2Na, sodium bromate, a perfume, a humectant such as pro;ylene glycol, amino aids and oils and fats such as silicone oil in addition to the betaine of the formula.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a perm solution containing betaine (also known as trimethylglycine, glycine betaine, alkyldimethyl betaine) as an active ingredient. In addition,
The perm solution according to the present invention is used for the purpose of wave formation or straightening of hair, and when a plurality of agents are used per treatment, it means all the agents used.

[0002]

2. Description of the Related Art Conventionally, various oil components, propylene glycol, amino acids, etc. have been used as a hair damage preventing agent for perm solution, but the conventional products are not sufficiently effective. No, it did not satisfy the user.

[0003]

Means for Solving the Problems As a result of intensive investigations by the present inventors to obtain a compound having an excellent hair-protecting function as a substance to be used in a perm solution, the above-mentioned betaine has an excellent hair-protecting action and after use. The present invention has been completed by discovering that it has the effect of improving the texture. That is, the present invention is a perm solution containing betaine represented by the formula (1) as an active ingredient. The hair-protecting function of betaine is presumed to be due to its excellent moisturizing power and good permeability to hair tissues.

For example, betaine was soluble in 160 parts by weight with respect to 100 parts by weight of water, and its moisturizing property was examined. The values shown in Table 1 were obtained.

[0005]

[Table 1]

[0006] The compounding amount of betaine of the formula (1) is 0.05 to 0.5% of the final product.
10 parts by weight, preferably 2 to 6 parts by weight.

The perm solution of the present invention comprises, in addition to the above essential components,
Substances usually used in perm solution, such as thioglycolic acid or its salts (ammonium, monoethanolamine, sodium, etc.), cysteine, alkalis (ammonia, monoethanolamine, etc.), surfactants (polyoxyethylene (20) lauryl ether) , Stearyltrimethylammonium chloride, etc.), stabilizers (ethylenediaminetetraacetic acid / 2Na, etc.), sodium bromate, fragrances, wetting agents (propylene glycol, etc.), amino acids, various oils and fats (silicone oil, etc.), etc. can be added. .

The perm solution of the present invention can be manufactured, filled and distributed according to a method usually used.

Example 1 Thioglycolic Acid Type 1 Liquid Component Amount (part by weight) Betaine 5.0 Ammonium thioglycolate (50% aqueous solution) 10.0 Ammonia water (28%) 3.0 Stearyltrimethylammonium chloride 0.1 Ethylenediaminetetraacetic acid ・ 2 sodium, proper amount Perfume, proper amount Total amount to 100 parts by weight with purified water Stir and mix components other than ammonium thioglycolate and ammonia water uniformly, and then add both and mix.

[0011]

Comparative Example 1 Thioglycolic acid type 1 liquid Ammonium thioglycolate (50% aqueous solution) 10.0 Ammonia water (28%) 3.0 Stearyltrimethylammonium chloride 0.1 Propylene glycol 5.0 Ethylenediaminetetraacetic acid / 2 sodium Proper amount Perfume Proper amount Make up to 100 parts by weight with purified water Uniformly stir and mix components other than ammonium thioglycolate and ammonia water, and then add and mix both

[0012]

Example 2 Cysteine Type 1 Liquid Betaine 5.0 Cysteine 5.0 Ammonium Thioglycolate 0.3 Monoethanolamine 2.0 Ethylenediaminetetraacetic acid / 2 sodium Proper amount Perfume Proper amount 100 parts by weight with purified water. Stir and mix each component uniformly

[0013]

Comparative Example 2 Cysteine type 1 liquid Cysteine 5.0 Ammonium thioglycolate 0.3 Monoethanolamine 2.0 Ethylenediaminetetraacetic acid / disodium Suitable amount Perfume Suitable amount Purified water makes the total amount 100 parts by weight Each component is uniform Stir to mix

[0014]

Example 3 Second Liquid Betaine 3.0 Sodium Bromate 5.0 Silicone Emulsion 1.0 Perfume Appropriate amount Purified water is added to 100 parts by weight.

[0015]

Comparative Example 3 Second Liquid Sodium Bromate 5.0 Silicone Emulsion 4.0 Perfume Appropriate amount Purified water makes the total amount 100 parts by weight The perm liquids shown in Examples 1 to 3 and Comparative Examples 1 to 3 respectively. It was evaluated by 10 panelists (female aged 20 to 36: straight hair). The number of people evaluated by experts having more than 10 years of beauty experience as "damaged hair" compared to before the implementation is shown.

[0016]

[Table 2]

Electron micrographs of the hairs of "untreated", "Comparative example 2 x Comparative example 3" and "Example 2 x Example 3" are shown in FIGS. The cuticles are lined up neatly in the “untreated” hair, whereas in “Comparative Example 2 ×
The cuticles are visible on the hair of Comparative Example 3 ”. On the other hand, in the case of the hair of “Example 2 × Example 3”, the cuticle does not emerge and the hair is in a normal state as in the case of the “untreated” hair.

[0018]

EFFECTS OF THE INVENTION According to the present invention, it is possible to provide a perm solution which is less damaged by addition of a small amount and has a very good feel after use.
