Description

DESCRIPTION

COSMETIC COMPOSITION FOR KERATIN FIBERS

TECHNICAL FIELD

The present invention relates to a cosmetic composition for keratin fibers such as hair.

BACKGROUND ART

A cosmetic composition for keratin fibers- such as hair, for example, a hair coloring composition and a hair bleaching composition, includes an alkaline agent. Very often alkaline agents have an offensive odor.

As the alkaline agent, ammonia is commonly used.

Ammonia is an excellent alkaline agent in terms of safety and performance of cosmetic treatments for keratin fibers. However, its malodor gives a strong negative influence to the usage of a cosmetic composition including ammonia for keratin fibers.

Therefore, elimination of ammonia odor from the cosmetic

composition is one of the important targets nowadays in the field of cosmetics for keratin fibers.

The current main method for reducing ammonia odor from a cosmetic composition for keratin fibers (this means evaporation of ammonia (odor) from the surface of the cosmetic composition) is to use another alkaline agent such as monoethanolamine instead of ammonia or to replace a part of the ammonia as disclosed in JP-A- HOl-213220 (1989) . However, monoethanolamine has an amine odor and this method also unfavorably affects the performance of cosmetic treatments for keratin fibers. For example, the ability to intensively color or bleach hair, which is a very important factor for coloring hair, is negatively affected when, coloring or bleaching hair using a cosmetic composition including an alkaline agent other than ammonia. In order to enhance coloring and bleaching efficiency, the amount of the alkaline agent other than ammonia may be increased or additional non-volatile alkaline agent (s) may be used together. However, the increase of the amount of the alkaline agent other than ammonia, such as

monoethanolamine, may create another issue such as increase of amine odor or safety limit due to a relatively large amount of non-volatile alkaline agent (s) .

DISCLOSURE OF INVENTION An objective of the present invention is to reduce the offensive odor of a cosmetic composition including an alkaline agent such as ammonia while maintaining good cosmetic performance, e.g., effective coloring or bleaching, of the cosmetic composition for keratin fibers such as hair, without causing another odor and safety limit.

BEST MODE FOR CARRYING OUT THE INVENTION

The inventors performed diligent research and found that a cosmetic composition for treating keratin fibers, which includes alkaline agent (s) other than ammonia and can be used in

combination with another cosmetic composition for oxidizing the keratin fibers, can be improved to enhance cosmetic performance of coloring or bleaching keratin fibers. Since the amount of the alkaline agent (s) other than ammonia, such as monoethanolamine, does not need to be increased, and the use of additional nonvolatile alkaline agent (s) is no longer necessary, the present invention can avoid the issues of another odor based on the non- ammonia and additional non-volatile alkaline agents and safety limit by a relatively large amount of the non-ammonia and additional non-volatile alkaline agents.

According to the present invention, the improvement of the cosmetic composition for treating keratin fibers such as hair can be achieved by specific conditions of the type and the amount of components in the cosmetic composition.

Thus, the cosmetic composition according to the present invention is characterized by comprising:

(a) at least one fatty alcohol other than oil;

(b) at least one oil;

(c) at least one nonionic surfactant;

(d) at least one anionic surfactant; and

(e) at least one non-volatile alkaline agent,

The multi-compartment system may be equipped with a means for mixing and/or applying the above compositions such as a valve and a nozzle.

Alternatively, the cosmetic composition according to the present invention may be a ready-to-use composition. For the purposes of the present invention, the expression "ready-to-use composition" is defined herein as a composition to be applied immediately to keratin fibers such as hair. Said "ready-to-use composition" may result from the extemporaneous mixing of the components of the cosmetic composition according to the present invention and at least one oxidizing agent as described above, and may be stored in unmodified form before use.

The pH of the cosmetic composition applied to the keratin fibers is generally, for example, from 4 to 12. It can range from 6 to 12, preferably 7 to_ll, and may be adjusted to .the desired value using at least one acidifying agent that is well known in the prior art.

The acidifying agents can be, for example, mineral or organic acids, for instance hydrochloric acid, orthophosphoric acid, carboxylic acids, for instance tartaric acid, citric acid, lactic acid, or sulphonic acids.

The cosmetic composition according to the present invention can be used in treating (e.g., coloring or bleaching) keratin fibers such as hair, comprising, for example, the steps of:

applying to wet or dry keratin fibers a cosmetic composition which is either prepared extemporaneously by mixing, just before the application to the keratin fibers, the cosmetic composition according to the present invention and another separate cosmetic composition comprising at least one oxidizing agent, or is the cosmetic composition according to the .present invention itself as a "ready-to-use" composition prepared as described above; leaving the cosmetic composition to act for an exposure time, such as ranging from 1 to 60 minutes approximately, and further such as from 5 to 45 minutes approximately;

rinsing the fibers; and

optionally washing them with shampoo, rinsing them again and then drying them.

The application of the cosmetic composition may be realized at room temperature or with the use of a warming device which is able to produce a temperature ranging from 40 to 220°C,

preferably ranging from 40 to 80°C.

EXAMPLES

The present invention will be described in more detail by way of examples, which however should not be construed as limiting the scope of the present invention.

Examples 1-14 and Comparative Examples 1-6

The following compositions according to Examples 1-14 and

Comparative Examples 1-6, shown in Tables 1-4, were prepared by mixing the components shown in Tables 1-4. The numerical values for the amounts of the components shown in the Tables are all based on "% by weight" as active raw materials.

Table 1

"RATIO A" in Tables 1-4 means the weight ratio of the total amounts (wt%) of the fatty alcohols to the amount (wt%) of the oil .

"HLB" in Tables 1-4 means a weighted average of HLB calculated as follows: {(the HLB value of Steareth-20) * (the amount (wt%) of Steareth-20) + (the HLB value of Ceteareth-33 )*( the amount (wt%) of Ceteareth-33) + (the HLB value of Glyceryl stearate) * (the amount (wt%) of Glyceryl stearate )}/{( the amount (wt%) of Steareth- 20) + (the amount (wt%) of Ceteareth-33 )+( the amount (wt%) of

Glyceryl stearate)}.

"RATIO B" in Tables 1-4 means a weight ratio of (the total

amounts (wt%) of the fatty alcohols )+ (the amount (wt%) of the oil(s) to the total amounts (wt%) of the nonionic surfactants.

[ΔΕ Evaluation]

Each formulation of Examples 1-14 and Comparative Examples 1-6 was mixed with a developer having the composition shown in Table 5 in a weight ratio of 1:1.5. lOg of the obtained mixture was applied on 10 g of a lock of natural Japanese black hair for 30 minutes at 27°C.

The hair lock was washed with warm water, and then shampooed once. After being dried, ΔΕ (between the color of the original hair and the color of the bleached hair under L^*a^*b^* system) was determined by using a colorimeter (Konica-Minolta : CM-508d) . For color intensity, 3 experiments were repeated and the result was

calculated as the average of these 3 data.

Table 5

The bleaching efficiency was also determined in accordance with the following criteria.

ΔΕ

Less than 5: Low

Between 5 and 6: Medium

More than 6: High

The results of the evaluation are shown in Tables 1-4. As shown in Tables 1-4, the hair lock treated with Examples 1-14 showed higher bleaching efficiency than Comparative Examples 1-6. These results demonstrate that Examples 1-14 can provide the hair with better bleaching effects.
