Background

Keratin fibers are widely found on human surfaces, such as, in particular, hair. For a long time, many people have sought to clean keratin fibers so as to feel comfortable in daily life and work. In response to the need for people to clean keratin fibers, various products have been developed, many of which are used to bring about cleaning effects and some other effects.

The keratin fibers, particularly the hair, are cleaned and treated to improve their appearance, color, style, etc. Thus, various cleansing and/or conditioning components are added directly to the shampoo. In addition, in addition to cleansing and conditioning functions, some other properties are important to appeal to consumers, such as special fragrance, good appearance, smooth feel, ease of use, etc. For example, many consumers prefer a smooth feel to the hair rather than tangled hair strands.

According to an embodiment, the composition according to the invention can be used for cleaning keratin fibres, in particular the hair, or the hair and scalp. Such use may manifest itself in a method of cleaning keratin fibres, in particular the hair, comprising the step of applying the composition of the invention to said keratin fibres.

The composition according to the invention is preferably used for the manufacture of shampoo products. The invention will be further illustrated by the following examples, which illustrate particularly advantageous embodiments.

Notwithstanding that the numerical ranges and parameters setting forth the broad scope of the invention are approximations, the numerical values set forth in the specific examples are reported as precisely as possible. Any numerical value, however, inherently contains certain errors necessarily resulting from the standard deviation found in their respective testing measurements. Accordingly, the following examples are intended to illustrate the invention without limiting its scope.

Examples

The amounts/concentrations of ingredients in the following compositions/formulations are expressed in weight percent relative to the total weight of each composition/formulation.

Materials not specifically described herein are each commercially available.

Example 1

Composition a and comparative composition B as in table 1 were formulated separately:

TABLE 1

The above-listed compositions a and B were prepared according to manufacturing methods known in the art.

Compositions a and B were obtained with shampoo products according to the invention.

Example 2

Compositions a and B were evaluated. An equivalent sample of a 6 gram, 27 cm chinese hair sample was used. The same DIASTRON MTT175 device, but with different components, was used for both experiments: the TOUCHAIR test (reported in N) and DETANGLE test (reported in N) for average friction and the average disentanglement force) were followed according to routine on the device for both tests. For each test, a relatively low value represents better results. The evaluation was performed according to the following steps:

1) Washing all hair samples twice (1.6 g+1.2 g/6 g hair samples) with cleaning compositions a-B according to procedure RC-MCI-OIP-003B;

2) The friction force of all samples was then measured under wet conditions using the TOUCHAIR test;

3) Reorganizing all hair samples into groups with similar average wet friction and standard deviation thereof;

4) Samples were treated separately with all products according to standard procedures, but applied 2 times (dose: 1.6 grams +1.2 grams);

5) The friction force of all samples was then measured under wet conditions using the TOUCHAIR test;

6) The hair samples were dried naturally overnight and kept in an H & T chamber (23 ℃,50% rh);

7) The friction of all samples was then measured again under dry conditions using the TOUCHAIR test;

8) All hair samples were blown in a T & H chamber by wind (10 minutes) to create tangles;

9) Measuring the disentangling force under dry conditions with disentangling test;

10 Twisting the hair samples in a mixer with water (10 s each) to create tangles;

11 Under humid conditions, the disentanglement force was measured with a wet disentanglement test.

The results are provided in table 2 below.

TABLE 2

Results	Composition A1	Comparative composition B
			Dry smoothness (N)	1.78	2.32
Wet smoothness (N)	2.11	2.2
			Wet disentanglement (N)	3.25	5.16

Referring to table 2, it was observed that composition a showed relatively better performance than composition B.
