Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a shampoo composition that imparts natural luster to hair after washing and exhibits excellent hair conditioning and conditioning effects.

PRIOR ART AND PROBLEMS In recent years, hair care has been widely practiced using methods such as Noguichi Manent Wave, hair color, hair color, hair dryer, etc. However, due to the spread of such hair care methods, hair ξThe hair is more likely to be damaged by these tools and chemicals, which causes the hair to lose its luster.
A problem has arisen in that it tends to be dry and has a soft feel.

Therefore, we use hair conditioners that add luster to hair after washing, and also give it suppleness, body, and ease of tp.
For the purpose of improving the Jungian effect, shampoo compositions containing animal and vegetable oils (Japanese Patent Application Laid-open No. 54-25906),
Adding protein (Japanese Patent Application Laid-Open No. 56-34613),
Or blending fatty acid ester (US Patent No. 3728)
447), but the method of blending these ingredients has widespread problems such as the effect of the surfactant contained in the shampoo composition, which prevents oil from being absorbed into the hair. The effects, hair conditioning, and Jung effect were not completely satisfactory. Therefore, there has been a strong demand for a shampoo composition that has both the shine of hair after washing and the hair conditioning effect.

Summary of the Invention The present inventors have developed a method that gives natural and excellent shine to hair after washing.
Moreover, in order to obtain a shampoo composition that exhibits hair conditioning effects such as suppleness and ease of curling, we conducted intensive research and found that a specific sulfosuccinic acid monoester, that is, the following general formula (I) % formula % (however, the formula R1 is an alkyl group having an average carbon number of 9 to 15, R2 is a hydrogen atom or a methyl group, AO is an oxyalkylene group having 2 to 3 carbon atoms, n is an integer of θ to 20, and M
1 and M2 each represent one selected from a hydrogen atom, an alkali metal ion, an ammonium ion, and a hydroxyammonium ion. ) and a quaternary nitrogen-containing water-soluble polymer, it gives the hair a natural and excellent shine effect, as well as a good hair conditioning effect, and contains both of these ingredients in combination. It has been found that a shampoo composition of the present invention has both a lustrous effect on hair, a conditioning effect, and a Jung effect, and achieves the above object.

Furthermore, in addition to both of the above components, water-soluble salts are blended,
In particular, it has been found that the effect is further exhibited by blending the compound in a weight ratio of 0.2 or more with respect to the compound of general formula (I), and the present invention has now been completed.

The reason why the combination of the compound of the general formula (I) and the quaternary element-containing water-soluble polymer gives a natural and excellent shine effect to the hair, as well as good condition and Jung effect. There are various possibilities, but in particular, is the sulfosuccinic acid monoester represented by general formula (I) quaternary nitrogen-containing water-soluble? The complex salt forms a complex salt with the hair trimmer, and this complex salt easily precipitates on the hair surface, and has a high affinity with the hair. It is thought that because it is adsorbed in large amounts to the hair, it exerts a hair shine effect, a hair conditioner, and a Jung effect.

In addition, the effect is increased by adding water-soluble salts.
This is presumed to be because the complex salt is salted out due to the presence of the water-soluble salt, promoting precipitation and adsorption onto the hair.

The present invention will be explained in more detail below.

Constitution of the Invention The sulfosuccinic acid monoester used in the present invention is represented by the following general formula (I).

Here, in the compound of general formula (I), R1 is a linear or branched alkyl group having an average carbon number of 9 to 15, specifically nonyl, decyl, undecyl, dodecyl,
Examples include tridecyl, tetradecyl, (ntadecyl) groups and mixtures thereof.In this case, there is no problem even if these include an alkyl group outside the range of 9 to 15 carbon atoms.The average number of carbon atoms in the alkyl group as a whole It is sufficient that the number of carbon atoms in the alkyl group is from 9 to 15, and good foaming power can be obtained by setting the average number of carbon atoms in the alkyl group within this range.On the other hand,
If the average carbon number of R1 is 8 or less or 16 or more, the foaming power of the Shangu composition will be insufficient and the object of the present invention will not be achieved.

In addition, R2 is a hydrogen atom or a methyl group, and AO is an oxyalkylene group having 2 to 3 carbon atoms, specifically oxyethylene and oxypropylene, but oxyethylene and oxypropylene are mixed. You may do so. Further, n is an integer of 0 to 20, preferably 0 to 10. If n is larger than 20, the foaming power of the shampoo composition will be poor and sufficient effects cannot be exhibited.

Ml and Ml are one selected from a hydrogen atom, an alkali metal ion, an ammonium ion, and a hydroxyammonium ion, and Ml and Ml may be the same or different. Here, examples of alkali metals include lithium, sodium, potassium, etc.

EXAMPLES Hereinafter, the present invention will be specifically explained by showing examples and comparative examples, but the present invention is not limited to the following examples.

Before explaining the Examples and Comparative Examples, methods for evaluating hair gloss, hair suppleness, and hair cohesiveness will be explained.

[Hair luster]

Apply the Shangu composition II evenly to the hair strands No. 101, and heat the hair at 40°C and 250°C. Soak for 10 seconds in warm water (J), wash, and rinse twice.

The gloss of the hair bundle after drying was visually judged by 10 judges, and if it was shiny compared to the gloss of the hair bundle treated with the standard shampoo composition (standard product), it was given 2 points, and if it was slightly shiny, it was given 1 point. 0 points if it's the same, -1 point if it's a little dull,
If the film lacks shine, a score of -2 is given, and the scores of the 10 judges are totaled to obtain the evaluation score.

[Hair suppleness]

As in the case of hair luster evaluation, the suppleness of hair bundles after washing and drying was judged by touch (by 10 judges), and was judged to be superior to the touch of hair bundles treated with a standard shampoo composition. 2 points if it is slightly better, 1 point if it is slightly better.
If it is equal, it will be given 0 points, if it is slightly inferior, it will be given 11 points, if it is inferior, it will be given 12 points, and the scores of the 10 judges will be totaled to form the evaluation score.

[Hair manageability]

In the same manner as in the case of determining the luster of hair, the cohesiveness of the washed and dried hair bundle after death was determined in the same manner as in determining the suppleness of hair, and an evaluation score was obtained.

If the hair gloss, hair suppleness, and hair manageability all have an evaluation score of 7 or more, it is determined that the soil is sufficiently effective for practical use.

[Examples 1 to 13. Comparative Examples 1 to 3 Seventeen types of shampoo compositions were prepared according to the formulations listed in Table @1, and the gloss, suppleness, and manageability of the hair after washing and drying were evaluated according to the evaluation method described above. The results are also listed in Table 1.

As is clear from the results in Table 1, the shampoo compositions of Examples 1 to 13 were found to be more effective at washing hair than the standard shampoo composition.
On the other hand, Comparative Example 1, which did not contain a quaternary nitrogen-containing cationic polymer, received good evaluations in terms of hair shine, suppleness, and hair straightness after drying.
The Shangu compositions of Comparative Example 2, which did not contain a sulfosuccinic acid monoester, and Comparative Example 3, which contained a sulfosuccinic acid monoester having a structure different from that of the compound represented by formula (I), improved hair gloss, suppleness, No improvement effect was observed in terms of cohesiveness.

[Example 14-22] Nine types of shampoo compositions were prepared according to the formulations listed in Table 2, and the gloss, suppleness, and manageability of the hair after washing and drying were evaluated in the same manner as in Examples 1 to 13 above. was evaluated. The results are also listed in Table 2.

As is clear from the results in Table 2, in the case of shampoo compositions (Examples 16 to 22) in which the weight ratio of water-soluble salt to sulfosuccinate is 0.2 or more, compared to the standard shampoo composition, After washing and drying the hair, it was observed that the shine, suppleness, and manageability of the hair were significantly improved.

[Examples 23 and 24] Two types of shampoo compositions were prepared according to the formulations listed in Table 3, and the gloss, suppleness, and manageability of the hair after washing and drying were evaluated in the same manner as before. The results are also listed in Table 3.

Even if it contains other ingredients such as Table 3, it will not be affected by these ingredients, and compared to standard shampoo compositions, the hair will have better shine, suppleness, and manageability.・
