Abstract

PROBLEM TO BE SOLVED: To obtain the subject composition, excellent in rinsing effect and little stimulant to the skin or hair by including a specific quantity of a water-soluble chitosan and a polymer treated to be cationic, and adjusting its pH in a specific range with a basic amino acid. SOLUTION: This composition contains (A) a water-soluble chitosan (e.g. hydroxypropyl chitosan, succinyl chitosan, succinylated carboxymethyl chitosan, chitosan-d1-pyrrolidone-carboxylate) at 0.4 to 2.0 wt.%, and (B) a polymer treated to be cationic e.g. chlorinated O-[2-hydroxy-3-(trimethylammonio) propyl]hydroxyethyl cellulose} at 0.3 to 2.0 wt.%, wherein the total content of the components A and B is 1.0 wt.% or more, the composition being adjusted at pH 7 to 10, preferably 8 to 9, with a basic amino acid (e.g. arginine, lysine or histidine).

2. Description of the Related Art Conventionally, a hair treatment composition such as a hair rinse mainly uses a cation activator such as a quaternary ammonium salt, and generally has an acidic liquidity (PH = about 3). . The cationic active agent, which is the main ingredient, has excellent rinsing effects (ie, effects on hair such as “strength”, “softness”, “moistness”, and “combability”), but it does not affect skin or scalp. There was a problem irritating.

As a means for reducing this irritation, a so-called non-cation rinse which does not use the above-mentioned cationic activator is known. However, this is for oily components such as fatty acid esters, hydrocarbons, higher alcohols, silicone oils, and lanolin, and higher alcohols and low molar ethylene oxide adducts, fatty acid lactate salts, and alkyl glycosides. The product is formulated by blending a product having good adsorptivity and has a poor rinsing effect, and can only be expected to have an "emollient effect" such as replenishment of oily components and retention of hair moisture.

[0004] On the other hand, a cationized polymer which can be expected to have a rinse effect other than the cationic activator has a lower degree of cationization and less irritation to the skin and scalp than the cationic activator, but has an effect on the hair. Has not been used as a main agent and has been blended in a rinse-in shampoo. In this case, the cationized polymer in the rinse-in shampoo forms a double salt with the anionic activator, and is present in a solubilized state due to the excess anionic activator and the amphoteric activator used in combination. The double salt in the solubilized state is adsorbed on the hair at the time of rinsing after washing the hair, that is, at the time when the solubilizing agent is diluted, thereby exhibiting a rinsing effect. However, the effect is insufficient compared with the cationic surfactant.

When the amount of the water-soluble chitosan is less than 0.4% by weight, the amount of the cationized polymer adsorbed on the hair is small, and the performance as a rinsing agent cannot be sufficiently exhibited. Is unfavorable in production because it thickens and separates. When the amount of the cationized polymer is less than 0.3% by weight, the amount adsorbed on the hair is not sufficient,
If it exceeds, the viscosity of the composition becomes remarkable, which is not preferable in production. The reason why the total amount is 1.0% by weight or more is that if the total amount is less than 1.0% by weight, the performance as a rinsing agent tends to be insufficient.

In the composition of the present invention, the pH must be adjusted to 7 to 10 (preferably 8 to 9) by a basic amino acid. First, the reason for using a basic amino acid instead of an alkaline earth metal salt as an alkaline agent for adjusting pH is to reduce irritation to the scalp and the like. in this case,
Although it is not particularly limited as long as it is a basic amino acid, preferred examples include arginine, lysine and histidine, and arginine is particularly preferred. Relatively small (about 0.5
(% By weight) can be adjusted to the target PH value. Next, the reason why the pH value is adjusted to 7 to 10 is that if the PH value is less than 7, the amount of the cationized polymer adsorbed on the hair is small, and the performance as a rinsing agent cannot be sufficiently exhibited. If the amount exceeds the above range, not only does the increase in the amount of adsorption to the hair not be observed, but the composition tends to thicken and separate as the amount of amino acid added increases, which is not preferable in production.

[0015] The hair treatment composition thus constituted is excellent in rinsing effect and less irritating to skin and scalp. This is because, first, the use of a cationized polymer and water-soluble chitosan reduces irritation to the scalp and the like.
Second, paying attention to zwitterionicity of the hair,
To make the carboxyl terminal of the hair an anion by making the above the isoelectric point (4.5-5.5) or more of the hair, and to improve the adsorption amount by having the reactivity with the cationized polymer. In addition, by using water-soluble chitosan having good adsorptivity to hair, sufficient function as a rinsing agent was imparted. Third, a basic amino acid was used as a PH regulator to help alleviate irritation. It is considered that the effects such as these have been achieved in combination.

As shown in Table 1, Example 1 is a composition containing an appropriate amount of the cationized polymer, water-soluble chitosan and basic amino acid of the present invention. The skin irritation is equivalent to that of Comparative Example 1 in which a non-cationic rinse is used, and the skin irritation is low, with the use of a non-cationic rinse. In addition, Examples 2 and 3 show that different types of cationized polymers are less irritating and can sufficiently exert the effect as a rinsing agent.

On the other hand, as shown in Table 1, Comparative Example 3 was a case where the basic amino acid was not blended and the pH was low, Comparative Example 4 was a case where hydroxypropyl chitosan was not blended, and Comparative Example 5 was a case where the cationized polymer was not blended. Comparative Example 6 when the total amount of and hydroxypropyl chitosan was less than 1.0% by weight
In the case where the amount of the cationized polymer is less than 0.3% by weight, the performance as a rinsing agent is not sufficient.
