The present invention relates to a composition for cleaning keratinous fibres, in particular the hair. The invention also relates to a method for cleaning keratinous fibres, in particular the skin, the scalp and/or the hair, using the composition of the present invention.

context

Keratinous fibers are widely present on the surface of the human body, for example in the hair. Many people have long sought to clean the keratinous fiber, in order to feel comfortable in everyday life and at work. Different products are developed to meet a person's keratinous fiber cleansing needs, many of which are used to provide both cleansing and some other effects.

Keratinous fibres, especially 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. Moreover, in addition to cleaning and conditioning functions, other properties are also important to attract consumers, for example, special fragrance, good appearance, smooth feeling, ease of use and others. For example, many consumers love the smooth feel of the hair instead of tangled hair.

One of the objects of the present invention is therefore a cleansing composition for cleaning keratinous fibers comprising:

at least one anionic surfactant, and/or at least one amphoteric surfactant;

at least one non-volatile silicone oil selected from polydialkylsiloxanes with terminal dimethylsilanol groups having 500 repeating units or more, and

at least one amino silicone.

For the purposes of the present invention, the term “silicone oil” denotes an oil comprising at least one silicon atom, and in particular at least one Si—O group. For the purposes of the present invention, the term "silicone oil" is interchangeable with the terms "polysiloxane" and "polysiloxane oil". For the purposes of the present invention, "amino silicones" are not considered a "silicone oil". Rather, amino silicones form an independent class of components that can be included in hair treatment compositions. A more detailed definition and non-limiting examples of amino silicones are provided below, under the heading “Amino Silicone”.

Of course, a composition according to the invention or envisaged according to a process of the invention can contain a mixture of silicone oils which is only partially constituted by such an oil.

The silicone oils which can be used in the compositions according to the invention are preferably non-volatile.

Amino silicone (VS)

The term "amino silicone" refers to any silicone comprising at least one primary, secondary or tertiary amine or a quaternary ammonium group (i.e. a quaternized group). For the purposes of the present invention, an "amino silicone" is not a "silicone oil". On the contrary, a silicone amine is a different component than a silicone oil in the hair treatment compositions of the present invention. A more detailed definition and non-limiting examples of silicone oils are provided above, under the heading “Silicone Oil”.

A silicone can bear the amine group on the backbone chain in the molecule, it is called amino-terminal silicone, or bear the amine group on the pendent chain, it is called amino-grafted silicone.

Compositions A and B listed above were prepared according to a method of manufacture known in the field.

Compositions A and B were obtained in a shampoo product according to the present invention.

Example 2

Compositions A and B were evaluated. Equivalent samples of 6g, 27cm Chinese hair strands were used. The same DIASTRON MTT175 device, but with different parts, was used for two tests: TOUCHAIR test (for the average friction force (indicated in N)) and DETANGLE test (for the average disentangling force (indicated in N) ), according to procedures common to the two tests on the device. For each trial, a relatively lower value represented a better result. The evaluation was carried out according to the following steps:

1) All the locks of hair were washed twice with cleansing compositions A and B (1.6g + 1.2g/6g lock of hair) according to procedure RC-MCI-OIP-003B;

2) Then, the friction force was measured for all the wicks with the TOUCHAIR test in wet conditions;

3) All the hair strands were grouped into groups having a similar average wet frictional force and its standard deviation;

4) The locks were respectively treated with all the products according to the standard procedures but with 2 applications (dosage: 1.6g + 1.2g);

5) Then, the frictional force was measured for all the locks with the TOUCHAIR test in wet conditions;

6) The hair strands were naturally dried overnight and stored in an H&T chamber (23°C, 50%RH);

7) The frictional force was then measured again for all the wicks with the TOUCHAIR test in the dry state;

8) All strands of hair are blown in a T&H chamber (10 minutes) to generate knots;

9) Detangling force was measured with the Detangle Test in the dry state;

10) Sections of hair were twisted in a blender with water (10s for each) to create knots;

11) Detangling force was measured with the Wet Detangle Test.

The results have been provided in Table 2 below.

Example 3

Compositions A and B were evaluated for their long-lasting performance, comparing them respectively with a marketed product from ADOLPH NOURISH & REPAIR SHAMPOO.

Six expert panelists evaluated the compositions by half-hair test. The evaluation was made after 24 hours of use of the compositions, which means that the dry performance was verified after 24 hours. Compared to the marketed product, any significantly different sensation was recorded, and the results have been provided in Table 3 below:

performance compared to the marketed product

Note: + means significantly better feel;

○ means similar feeling.

Example 4

Compositions A and B were evaluated. Equivalent samples of 6g, 27cm Chinese hair strands were used.

Test Compositions A and B (2.4 g) were applied to the 6 g lock of hair, and washed off according to standard procedure RC-MCI-OIP-003B.

Hair strands were naturally dried overnight and stored in an H&T chamber (23°C, 50% RH);

Six experts formed from a panel rated the lock of hair on softness, suppleness with a standard gesture and gave the ratings.

The ratings were compared to those of a reference sample: Adolph Nourish and Repair Shampoo, and calculated as follows:

-2 means very clearly less good;

-1 means significantly worse;

0 means similar performance;

+1 means significantly better;

+2 means significantly better;

The average scores of the 6 experts were counted and calculated for the averages. Average ratings have been provided in Table 4 below.

A difference greater than 0.5 is considered a significant difference.

Test method: Composition A Composition B Smooth hair +0.8 +0.8 soft hair +0.6 +0.2

Referring to Table 4, it was observed that composition A exhibited better performance than composition B.
