Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to a hair protecting effect,
The present invention relates to a hair treatment agent having excellent conditioning effects such as moisturizing effect and smoothness.

[0002]

2. Description of the Related Art In recent years, consumers have become more individualized, and various treatments have been applied to hair. However, on the other hand, cuticles and oils that protect hair are removed for shampooing with shampoo containing anionic surfactant as a main component, chemical treatment such as permanent wave, physical treatment such as dryer and brushing, etc. Hair damage is increasing, such as the occurrence of split ends and cuts, and loss of smoothness.

[0003] Therefore, in order to prevent these adverse effects, a hair rinse agent, a hair conditioner, and the like, which contain a cationic surfactant as an active ingredient, are said to have a conditioning effect such as a hair protection effect, a moisturizing effect, and smoothness. It is used in hair treatments such as hair treatments. However, with a cationic surfactant alone, sufficient effects are not obtained with respect to conditioning effects such as a hair protecting effect, a moisturizing effect, and smoothness.

[0004] Therefore, it has been proposed that conventional hair treatment agents such as hair rinse agents, hair conditioners, and hair treatments contain fats and oils such as higher alcohols, glycerides and liquid paraffin for the purpose of improving these drawbacks. ing. For the purpose of preventing hair damage and a decrease in moisturizing properties, it has been proposed to incorporate silicone oil (for example, JP-A-63-222109) or to blend an animal protein derivative (for example, And JP-A-5-85921.

However, by using fats and oils such as higher alcohols, glycerides, and liquid paraffin,
Although some effects can be obtained in terms of improving the hair conditioning effect, the hair protection effect, the moisturizing effect, and the like are not sufficiently satisfactory. Also, silicone oil has insufficient hair moisturizing effect, and animal protein derivatives have not been able to obtain satisfactory conditioning effects such as smoothness.

On the other hand, the present inventors have proposed that when several kinds of lipid components are combined at a specific ratio, a liquid crystal structure can be formed relatively easily and an excellent moisturizing effect can be obtained (Japanese Patent Application Laid-Open No. 7-18).
No. 7987). The publication relates to "a skin cosmetic comprising at least one selected from ceramide, glucosylceramide and galactosylceramide, and cholesterol, fatty acid and water-soluble polymer as essential components". The effect lies in "improving or restoring the skin to a healthy state by enhancing and maintaining the moisture retention function of the skin".

The present inventors have conducted intensive studies in order to apply the technology disclosed in the above-mentioned publication not only to the field of “skin” but also to the field of “hair”. It has been found that by combining an activator, it is possible to obtain a hair treatment agent which is excellent in hair protection and moisturizing effects, and has a conditioning effect such as moist feeling and prevention of split ends, and has completed the present invention.

An object of the present invention is to provide a hair treatment agent which has a hair protecting effect and a moisturizing effect, and has a conditioning effect such as smoothness and prevention of split ends.

[0009]

Means for Solving the Problems To achieve the above object, the hair treatment composition of the present invention has the following constitution. That is, it is a hair treatment agent containing, as essential components, at least one selected from ceramide, glucosylceramide, and galactosylceramide, and cholesterol, a fatty acid, and a cationic surfactant. Furthermore, in order to further enhance the conditioning effect, it is a hair treatment agent in which a wax ester and a cholesterol ester are added to the above components.

Examples 1 to 4 and Comparative Examples 1 to 4 (Hair Rinsing) Table 1 shows the compositions of Examples 1 to 4 and Table 2 shows the compositions of Comparative Examples 1 to 4. These compositions were prepared according to the usual methods. The test methods used in the examples and comparative examples are as follows.

(Hair protecting effect, moisturizing effect and conditioning effect) Hair of a Japanese woman who has not been subjected to the permanent wave treatment is bundled with 10 g (15 to 20 cm), washed with a 10% aqueous sodium dodecyl sulfate solution and rinsed thoroughly. After that, each hair treatment agent was evenly applied and rinsed with warm water for 30 seconds, followed by a menu of towel drying, drying with a dryer, and brushing a certain number of times.
The test was repeated twice to evaluate the "degree of split ends", "moisturizing effect", "smoothness of hair", and "gloss of hair". In addition, each evaluation is
The evaluation was performed according to the following criteria. "Occurrence of split ends"◎; no increase in split ends ○; almost no increase in split ends △; slight increase in split ends ×; large increase in split ends "Moisturizing effect" , "Smoothness of hair", "Gloss of hair"◎; very good ○; slightly good △; not so good ×; bad

[Table 2]

Table 3 shows the evaluation results of Examples 1 to 4 and Comparative Examples 1 to 4.

[0029]

[Table 3]

As shown in Table 3, the compositions of the present invention (Table 1: Examples 1 to 4) were compared with the compositions not satisfying the conditions of the essential components (Table 2: Comparative Examples 1 to 4). All showed excellent results. In addition, Example 2 is a composition based on “Claims and Claims 2”, but includes other compositions based on “Claim 1” (Examples 1, 3 and 4). The items were the best. This means that the essential component of claim 1 is at least one selected from ceramide, glucosylceramide and galactosylceramide, cholesterol, fatty acid and cationic surfactant, whereas the essential component of claim 2 further comprises a wax. It may be related to the addition of esters and cholesterol esters. That is, the synergistic effect is remarkably exhibited by newly adding the functional component, and the hair protecting effect, the moisturizing effect, and the conditioning effect, which are reductions in the occurrence of split ends, are enhanced.

Example 5 (Heart Treatment) Table 4 also shows the composition of Example 5 and the results of a practical test. These compositions were prepared according to the usual methods. The test methods used in the examples are as follows.

(Practical test) The hair treatment agent in each example was subjected to the permanent wave treatment once a day for 20 weeks by a normal method for 20 weeks. The degree of occurrence, "moisturizing effect", "smoothness of hair", and "gloss of hair" were evaluated. In addition, each evaluation was performed based on the following criteria. "Degree of split ends" 毛: 18 or more people with no increase in split ends ○; 14 to 17 people with no increase in split ends △; no increase in split ends 8 to 13 people ×; no increase in split ends 7 or less people “moisturizing effect”, “smoothness of hair”, “gloss of hair” ◎; 18 or more ○: 14-17 people answered good △: 8-13 people answered good ×: 7 or less people answered good

The test methods used in the examples and comparative examples are the same as the above-mentioned "hair protection effect, moisturizing effect and conditioning effect".

[0036]

[Table 5]

As shown in Table 5, the hair conditioner composition of the present invention (Example 6) was prepared according to the following claims.
Claim 2 ", but compared with a composition that does not satisfy the conditions of the essential components of the present invention (Comparative Example 5),
The results of various tests showed excellent characteristics in all items. Further, in Examples 7 to 9, the weight ratio of the lipid composition of the present invention was such that ceramide, glucosylceramide,
At least one selected from galactosylceramide is 0.5 to 5.0, cholesterol is 0.5 to 5.0, fatty acid is 2.0 to 20.0, and wax ester is 0.1 to 5.0.
10.0, since the cholesterol ester does not satisfy the condition of 0.2 to 3.0, it is slightly inferior to the effect of Example 6, but is compared with the composition (Comparative Example 5) which does not satisfy the condition of the essential component of the present invention. The results of the tests showed excellent characteristics in all items.
