DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hair conditioning composition, which has low irritation, can supply sufficient moisture to hair, and has excellent smoothness when dry. Another object of the present invention is to provide a hair conditioning composition capable of imparting the following.

[0002]

2. Description of the Related Art In general, hair after perm treatment, hair dyeing treatment, or after washing with shampoo loses a smooth texture, produces a hard and crisp feel, and has poor combability, split ends and cut ends. Hair and the like tend to be easily generated. This is due to the breakage of cystine bonds in the hair by a permanent wave agent, damage to keratin in the hair by a hair dye, and excessive degreasing by shampoo,
Especially in recent years, permanent waves and hair dyes,
As hair washing with shampoos has become widespread, damage such as split ends and cut hairs is likely to occur on hair.

Therefore, in order to eliminate such damage to the hair, various conditioning agents such as hair rinse and hair treatment are usually used. This conditioning agent generally imparts flexibility and gloss to hair, and replenishes oil excessively degreased with shampoo to give the hair a smooth, comb-like finish to the hair, and furthermore, it is generated on the hair. It has the effect of preventing static electricity and improving hair styling. The function of such a conditioning agent is due to additives mixed with the cationic active agent used as a main component.
Specifically, conditioning agents such as hair rinses and hair treatments mainly contain a cationic surfactant such as a quaternary ammonium salt represented by dialkyldimethylammonium chloride or alkyltrimethylammonium chloride, for example. A compound containing various additives such as a certain oil component and a water-soluble polymer compound is generally known.

[0004]

However, cationic surfactants such as quaternary ammonium salts which have been conventionally used as a main component of conditioning agents have high irritation to hair and scalp, and are not safe. There was an issue. Further, such a conditioning agent shows a good effect on the combability and smoothness of the hair at the time of application, rinsing, and after drying, but gives a moist and smooth finish to the hair at the time of drying. There is also a problem that the feeling cannot be sufficiently given. For example, in order to improve the moist feeling of the hair after drying, it has been attempted to mix a large amount of oil such as silicone, but in this case, by mixing a large amount of oil,
Conversely, there has been a problem that the conditioning agent is not sufficiently distributed to the applied hair and stickiness occurs after drying, so that a good finish feeling cannot be obtained.

[0005] Therefore, the industry overcomes the drawbacks of the above-mentioned conventional conditioning agents, has excellent safety on the scalp and hair, and gives excellent dry hair a moist and smooth finish. Creation of an agent composition has been desired.

Preferred examples of the hydrocarbon-based oily substances among the oily substances include, but are not limited to, liquid paraffin, volatile isoparaffin, squalane, petrolatum, ceresin, and microcrystalline wax. Examples of the fatty acid esters include diisopropyl adipate, isopropyl palmitate, and isopropyl myristate. Examples of the silicone oils include dimethyl polysiloxane and methylphenyl polysiloxane. Examples of the animal and vegetable oils and fats include olive oil and camellia oil. Etc. are exemplified as preferred examples, but are not particularly limited. In the present invention, such an oily substance is not particularly limited, but is incorporated in an amount of 2.0 to 20.0% by weight based on the total amount of the components of the hair conditioning agent composition. The reason for this is that if the amount of the oily substance is less than 2.0% by weight, smoothness to the hair is not sufficiently given,
On the other hand, if the content is more than 20.0% by weight, a sticky feeling is given to the hair, which is not preferable in any case.

Specific examples of the monoglyceride type anionic surfactant represented by the formula (5) include sodium stearyl glyceryl sulfate, sodium cetyl glyceryl sulfate, sodium lauroyl glyceryl sulfate, sodium palmitoyl glyceryl sulfate, and coconut oil. Sodium fatty acid glyceryl sulfate, hydrogenated coconut oil sodium glyceryl sulfate, triethanolamine stearyl glyceryl sulfate, potassium lauroyl glyceryl sulfate, sodium palmitoyl glyceryl phosphate, sodium hydrogenated coconut oil glyceryl phosphate, etc. are exemplified as preferred examples. There is no particular limitation.

The monoglyceride type anionic surfactant as described above is used in an amount of 0.1 to 4.0% by weight, more preferably 0.5 to 3.0% by weight, based on the total amount of the hair conditioning composition. %. The reason for this is that the blending amount of the monoglyceride type anionic surfactant is
If the amount is less than 0.1% by weight, the desired conditioning effect of the present invention is not sufficiently exhibited, while if the amount exceeds 4.0% by weight, the protein modification rate of the hair conditioning agent composition increases. This is because it is not preferable in any case since a problem arises in safety.

The preferred straight-chain higher alcohols having 12 to 22 carbon atoms include lauryl alcohol, myristyl alcohol, cetyl alcohol, and behenyl alcohol. Preferred examples thereof include, but more preferably, 16 to 22 carbon atoms. Is preferably used. Such a straight chain higher alcohol having 12 to 22 carbon atoms is not particularly limited in the present invention, but may be 0.5 to 0.5 parts of the total amount of the hair conditioning agent composition.

EXAMPLES The effects of the hair conditioning composition according to the present invention will be further clarified below with reference to examples.

(Example 1 and Comparative Examples 1 to 4) Monoglyceride type anionic surfactants, amino acid surfactants, anionic surfactants, amphoteric surfactants and cationic surfactants are shown in Table 1 respectively. Liquid paraffin, cetyl alcohol and the like were blended according to the formulation shown to prepare the hair conditioning composition of Example 1 and Comparative Examples 1-4. In addition, all the numbers in a table | surface show a weight%.

[Table 1]

[0017]

[Test example]

(1) Hair moisture content test 0.25 g of each of the hair conditioning agent compositions obtained in the above Examples and Comparative Examples was applied to a hair bundle of about 1 g and about 11 cm, and the resulting hair was tested in running water of about 40 ° C. for 30 seconds. After rinsing and air-drying, use the Aqua Checker (Byanette Aqua Checker HC100
0 / Fine Cosmetic Co., Ltd.) was used to measure the water content of the hair. Those with a hair moisture content of 10% or less were evaluated as x, those with 11 to 12% as △, and those with 13% or more as ○. Table 2 shows the results.

[Table 2]

(2) Evaluation of Smoothness of Hair A hair bundle of about 1 g and about 11 cm was used, and 0.25 g of each of the hair conditioning agent compositions obtained in the above Examples and Comparative Examples was applied to the hair bundle. 3 in running water of about 40 ° C
After rinsing for 0 seconds, air dried naturally,
Surface tester (KES-SF / Kato Tech Co., Ltd.)
Was used to measure the average coefficient of friction of each. The average friction coefficient was similarly measured for the hair bundle similarly treated only with water, and the ratio of these average friction coefficients was expressed as the amount of change. If the value of the amount of change is less than 0.85, the result is ○.
85 were evaluated as Δ, and those exceeding 0.95 were evaluated as ×. Table 2 shows the results.

(3) Irritation test (Protein denaturation test) Buffer 1 of pH 6 containing 0.025% ovalbumin
In 10 ml of a 10% dilution of the hair conditioning agent composition obtained in each of the above Examples and Comparative Examples, was added to 0.1 ml each.
After adding 5 ml each, and allowing to stand at 25 ° C. for 24 hours, the peak area (220 nm) of ovalbumin was determined by high performance liquid chromatography, and the ovalbumin denaturation ratio was calculated from the following equation. Ao: Peak area of ovalbumin when purified water was added instead of aqueous solution of hair conditioning agent. As: Peak area of ovalbumin when aqueous solution of hair conditioning agent of Examples and Comparative Examples was added. X, 25 when the value is 50% or more
〜50% was evaluated as Δ, and less than 25% was evaluated as ○. Table 2 shows the results.

As is clear from the results in Table 2, both the compound containing the anionic surfactant (Comparative Example 2) and the compound containing the cationic surfactant (Comparative Example 4) had a high protein denaturation rate. It turns out that irritation is great. Also,
It is found that the composition containing the amphoteric surfactant (Comparative Example 3) has a high friction coefficient of hair and cannot provide good smoothness. Furthermore, a composition containing an amino acid surfactant (Comparative Example 1), a composition containing an anionic surfactant (Comparative Example 2), a composition containing an amphoteric surfactant (Comparative Example 3), and a cationic surfactant It can be seen that in all the compositions containing the agent (Comparative Example 4), the water content of the hair was low.
