Description

COSMETIC COMPOSITION, USE OF A COSMETIC COMPOSITION, PROCESS FOR THE PREPARATION OF A COSMETIC COMPOSITION AND METHOD FOR

STYLING THE HAIR FIELD OF THE INVENTION

The present invention relates to a new styling and caring cosmetic composition for keratin fibers, especially for curly hair, containing a fatty amine, a wax, an oily compound derived from vegetal origin and a fatty alcohol. Additionally, the present invention is related to the use of the cosmetic composition, process for the preparation of the cosmetic composition and a method for styling the hair.

The present invention also relates to a method of cold processing for inserting the wax into the composition.

BACKGROUND OF THE INVENTION

People have been using a number of cosmetic and personal care compositions to enhance the look and feel of keratin fibers, such as the hair. Exposure to humid conditions and chemical procedures can cause an excessively expanded volume (i.e., “frizz volume”), or appear frizzy. This frizzy condition of hair often appears unruly and is often characterized with a multiplicity of fly-away strands of hair. Frizzy hair is unsightly and makes it difficult for consumers to control and maintain the hair style. This frizzy condition is particularly pronounced in dry, damaged or curly hair.

Curly hair tends to become frizzy, undefined curls and significantly expand in volume when exposed to high humidity conditions or changes in humidity environment.

For temporary control and definition of the curls, styling mousse, gels, lotions, and spray compositions have been employed to combat these conditions.

Many attempts of compositions have been developed in order to conditioning, discipline, define and control the hair, in particular curly hair, enhancing/maintaining curl definition, curl retention, and curl regularity, and/or enhancing shine, without leaving the hair feeling and/or looking unnatural and stiff.

Unfortunately, the products of the state of the art can still leave the hair stiff and unmanageable after application and negatively affect ease of combing and hair feel.

Therefore, it is desirable to formulate a leave-on hair cosmetic composition without the above-described drawbacks, that delivers high styling and caring for curly hair (maintaining the hair smooth) and that can impart superior frizz and volume control to the hair. It is also desirable for manufacturers of hair cosmetic products to continuously investigate new ingredients and/or combination of ingredients that can be formulated into a final composition that can impart many cosmetic benefits but which remains stable or which does not exhibit phase separation.

It should be mentioned that the stabilization of cosmetic products is an important matter, due to different chemical classes of the ingredients. Thus, the incorporation of certain ingredients such as waxes, which are known to provide cosmetic benefits to hair, can present a formulation and/or a manufacturing challenge, especially, when combined with other ingredients.

In this sense, the inventors of the present invention surprisingly achieved a new cosmetic composition which is stable over the time, delivers high styling and caring for curly hair due to the combination of a fatty amine, a wax, an oily compound derived from vegetal origin and a fatty alcohol.

The new cosmetic composition delivers high styling and caring for curly hair. It may be in the form of a leave-on cosmetic composition, such as combing cream composition (leave on).

SUMMARY OF THE INVENTION

The present invention is directed to a cosmetic composition comprising:

(a) at least one fatty amine; (b) a liquid carnauba wax; (c) at least one fatty alcohol; and (d) water.

In other words, by the combination of cationic surfactants and natural fatty compound with vegetable wax emulsion, was possible to achieve a composition which delivers styling and care without using silicones, that is able to control the frizz and improve the visual aspect of the curls (more curl definition, curl regularity, and discipline).

The process of manufacturing the compositions of the present invention is different from a traditional manufacturing process involving waxes. In the traditional process, the wax is usually added to the composition before emulsification at a temperature higher than the melting point of the wax, typically from about 80-85 °C. In the process of the present invention, the liquid wax or wax emulsion is added at the end after the mixture/composition has been cooled down (cold processing).

By way of non-limiting illustration, the invention will now be described with reference to the following examples.

EXAMPLES EXAMPLES 1 to 3

Suitable compositions according to the present invention, but not limited to, are as Examples 1 to 3, as follows:

^* Available as a wax emulsion or liquid wax under the tradename HOSTAPUR CW from the company CLARIANT EXAMPLE 4

A comparative composition is as Example 4 below:

EXAMPLE 5 The compositions of EX. 1 to EX. 3 (present invention) and EX. 4

(comparative) were submitted to an expert test, wherein six volunteers tested both products as a daily product. The results were measured/observed by the experts in wet and dry hair.

As a result, the compositions of EX. 1 to EX. 3 present on wet hair, less frizz, less volume, more curl regularity and smooth touch, over the composition of EX. 4.

Additionally, the compositions of EX. 1 to EX. 3 present on dry hair, more curl regularity, more curl definition, discipline, shine and less frizz, over the composition of EX. 4. EXAMPLES 6 to 7

A Swatch Test was performed in order to compare the compositions of EX. 6 and EX.7, following the steps below: Step (a) (conventional sulfate-based Shampoo)

1 ) Wet swatch under tap water passing index and thumb fingers 5 times through the swatch.

2) Remove water excess with fingers (2 times)

3) Apply DOP shampoo (0,4g/swatch g) and rub it on swatch 6 times 4) Leave it for aboutl min

5) Rinse swatch under tap water passing index and thumb fingers 15 times through the swatch.

6) Remove water excess with fingers (2 times)

Step (b) (Compositions of EX. 6 and EX. 7) 1 ) Wet swatch under tap water passing index and thumb fingers 5 times through the swatch.

2) Remove water excess with fingers (2 times)

3) Apply each of the compositions of EX. 6 and EX. 7 (0,4g/swatch g) and rub it on swatch 6 times 4) Hold swatch with one hand and with the other create curl shape by moving hand up and down twice. 5) Let it dry

Step (c) (Shape breakage)

1) After 24h pass index and thumb fingers slowly through the swatch.

It was observed that after step (c), the hair treated or contacted with EX. 6 (with beeswax) presented less curl definition, heavier feel, and more frizz when compared to the hair treated or contacted with EX. 7 (with Carnauba). These results could be verified in FIG. 1.
