Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a hair rinse composition that imparts cohesiveness to hair without making it sticky and has a high shine-imparting effect.

[Conventional technology]

Normally, hair is covered with sebum secreted from the hair itself, but when hair is washed with soap, synthetic detergent, etc., more sebum is removed than necessary. As a result, the hair after washing loses its smoothness and feels dry and hard, making it difficult to comb through the hair and causing split ends. For this reason,
In order to solve the inconveniences associated with the removal of sebum, various hair rinses have been developed as hair treatment agents after washing.
It is used. Typical of these hair rinses contain quaternary ammonium salts such as dialkyldimethylammonium chloride and alkyltrimethylammonium chloride as the main active ingredient.

In order for these hair rinses to prevent hair from squeaking and tangling after washing and to improve the finish when dry, the quaternary ammonium salt must be adsorbed or adhered to the hair. However, conventional hair rinses have problems in the ability to remove and adsorb the ammonium salt, regardless of the form in which they are used, and are not fully satisfactory.

In addition, in recent years, with the spread of permanent waves, hair color, hot curlers, hair dryers, etc., hair is often damaged and loses its youthful luster. A hair rinse is desired. However, hair rinses containing oils such as quaternary ammonium salts and higher alcohols have the disadvantage that they hardly exhibit any gloss-imparting effects.

Various studies have already been conducted to add luster to hair.
A typical example is one containing silicone oil (French Patent No. 1504102, JP-A-52
-66638, JP-A-55-124711, JP-A-56-86113, JP-A-56-92808, etc.), those that form a film on the hair (U.S. Pat.
820550, German Patent No. 2003487, etc.), those containing protein derivatives (Japanese Patent Laid-Open No. 5
6-104809, JP-A-56-34613, etc.). However, none of these compositions has a sufficient gloss imparting effect.

On the other hand, a hair rinse agent consisting of a combination of a mono-long chain alkyl type quaternary ammonium salt having 22 to 24 carbon atoms and an alkyl ether type phosphoric acid ester to which a specific number of moles of alkylene oxide is added can impart shine to hair. Also known (Japanese Unexamined Patent Publication No. 61-12608), however, in this case it is not possible to impart sufficient manageability to the hair.

[Problem that the invention seeks to solve]

The present invention was made in view of the above circumstances, and an object of the present invention is to provide a hair rinse composition that imparts cohesiveness to hair without making it sticky and has a high gloss imparting effect.

[Means for solving problems]

The present inventors conducted extensive research to achieve the above object, and found that a specific quaternary ammonium salt (A), a specific phosphoric acid ester (B), and a lanolin fat (C) were used in combination. was found to be effective. That is, among the above components, if components (A) and (B) are simply used in combination without component (C), the effect of imparting manageability to hair is inferior, and only components (A) and (C) are combined. When used in combination, or when only components (B) and (C) are used together, the effect of imparting shine to the hair is insufficient and the hair becomes sticky. On the other hand, the component (A
), (B) and (C), they act synergistically to provide hair with manageability and shine without making it sticky. The present invention is based on such knowledge.

The present invention comprises as essential components one or more quaternary ammonium salts represented by the following formula (I), one or more phosphoric esters represented by the following formula (II), and lanolin fat. A hair rinse composition is provided.

(Here, R4, R2, R3 and R4 are alkyl groups,

20 panelists about the “shininess” of hair strands after leaving them day and night
A sensory evaluation was conducted. Evaluation is 1.0% by weight stearyltrimethylammonium chloride, 3.0% by weight
Based on a sample (Comparative Example 1) obtained by adding cetyl alcohol, 10% by weight of propylene glycol, and water to 100.0% by weight, evaluation was performed using the following 5-level evaluation.

◎: Very good O: Good △: Equally good ×: Inferior
xx=Very poor evaluation of cohesiveness Hair was treated in the same manner as in the gloss evaluation, and sensory evaluation was performed by 20 panelists using the same criteria.

<Examples 1 to 18, Comparative Examples 1 to 11> 29 types of hair rinse compositions whose component compositions are shown in Tables 1 and 2 were prepared and evaluated for imparting gloss and manageability to hair.

The results are also listed in the same table.

Note that the numerical values shown in the table below indicate the blending amount (% by weight). Further, in the phosphoric acid esters having a polyoxyethylene group or a polyoxypropylene group described below, the number written after the polyoxyethylene or polyoxypropylene indicates the number of moles of ethylene oxide or propylene oxide added.

From the results in Tables 1 and 2, when phosphate ester is not included (Comparative Examples 1 and 2), sufficient effects are not obtained in terms of imparting gloss and manageability to the hair.
Cases containing no quaternary ammonium salt (Comparative Examples 3 to 8)
When lanolin is not included (Comparative Example 9), the effect of imparting cohesiveness is inferior, and the effect of imparting cohesion is inferior.
It has been found that even if a phosphoric acid ester is blended, the effect is not sufficient when the number of moles of alkylene oxide added is outside the range of the present invention (Comparative Examples 10 to 11). In contrast, all of the compositions of the present invention (Examples 1 to 18) were found to impart satisfactory shine and manageability to hair.

<Examples 19 to 27 and Comparative Examples 12 to 13> Eleven types of hair rinse compositions whose component compositions are shown in Table 3 were prepared,
Evaluations were made regarding the imparting of shine and manageability to hair. The results are also listed in Table 3.

From the results in Table 3, it is found that when the oil or fat is other than lanolin oil (Comparative Examples 12 to 13), the effect of imparting cohesiveness to hair is particularly poor.

On the other hand, it is recognized that all the compositions of the present invention are excellent in the effect of imparting gloss and manageability to hair.

<Example 28 and Comparative Example 14> Two types of hair rinse compositions having the formulations shown in Table 4 were prepared and evaluated for imparting gloss and manageability to hair. In this case, the evaluation was performed using a 2% diluted solution of hair rinse agent composition 20ON at 40°C.
cm) was immersed for 5 seconds, rinsed twice with 200 g of 40°C warm water for 30 seconds each, and dried.

The results are also listed in Table 4.

Table 4 As is clear from the results in Table 4, the hair rinse composition of the present invention has an effect of imparting shine and cohesiveness that is superior to that of the conventional hair rinse composition that does not contain phosphate ester, and this effect is greater than that of the conventional hair rinse composition that does not contain phosphate ester. It has been observed that it is retained even when added.

<Example 29> A hair rinse composition having the formulation shown in Table 5 was prepared, and its properties were evaluated through practical use. As a result, this composition has the effect of imparting shine and manageability to hair without impairing its natural texture when finished.
