Description

Title of the invention: Composition for cleaning keratin fibers and its use Technical field

[0001] The present invention relates to a composition for cleaning keratin fibers, in particular hair. The invention also relates to a process for cleaning keratin fibers, in particular skin, scalp and / or hair, using the composition of the present invention. Context

[0002] Keratin fibers are widely present on the surface of the human body, for example, especially in the hair. Many people have long sought to clean the keratin fiber, in order to feel comfortable in daily life and at work. Various products are developed to meet the requirements of cleaning the person's keratin fiber, many of which are used to provide both cleaning and some other effects.

[0003] Keratin fibers, especially hair, are cleaned and treated to improve their appearance, color, style, etc. Thus, various cleansing and / or conditioning components are added directly into the shampoo. Furthermore, in addition to the cleansing and conditioning functions, some other properties are also important to attract consumers, for example, a special fragrance, good appearance, smooth feel, ease of use, and the like. For example, many consumers like the smooth feel of the hair instead of the tangle of the strands. Summary of the invention

[0004] One of the objects of the present invention is therefore a cleaning composition for cleaning keratin fibers comprising:

[0005] at least one cationic polymer, comprising a cationic cellulose copolymer or cellulose derivative grafted with a water-soluble quaternary ammonium monomer, optionally accompanied by an additional cationic polymer;

[0006] at least one anionic surfactant, and / or at least one amphoteric surfactant;

[0007] at least one thickening agent; and

[0008] optionally, at least one silicone oil.

[0009] The composition according to the present invention is particularly useful for a shampoo product.

[0010] The present invention also relates to a process for cleaning keratin fibers, in particular keratin fibers on the surface of the body, in particular hair, using the cleaning composition according to the invention.

[0111] These additives may be variously selected by those skilled in the art in order to prepare a composition which exhibits the desired properties, for example, consistency or texture. In particular, the additives, if used, and their amounts are determined particularly according to the specific products / applications thereof, for example, lotion, leave-in conditioner, shampoo, cream, conditioner with rinsing, emulsion and the like.

[0112] These additives may be present in the composition in an amount ranging from 0.01% to 90% based on the total weight of the composition and further from 0.1% to 50% (if present), including all intermediate ranges and sub-ranges. Method and use

[0113] The composition according to the present invention can generally be prepared according to the general knowledge of a person skilled in the art. Nevertheless, it is understood that a person skilled in the art can choose the preparation method, on the basis of his general knowledge, taking into account the nature of the constituents used, for example their solubility in the vehicle, and the application envisaged for the compositions or the kit.

[0114] According to one embodiment, the composition according to the present invention can be used for cleaning keratin fibers, in particular hair, or hair with the scalp. This use can be manifested as a process for cleaning keratin fibers, in particular hair, comprising the step of applying to said keratin fibers the composition of the present invention.

[0115] The composition according to the present invention is preferably useful for manufacturing a shampoo product. The invention will be illustrated in more detail by the following examples, which present particularly advantageous embodiments.

[0116] Although the numerical ranges and parameters defining the general scope of the present invention are approximations, the numerical values ​​indicated in the specific examples are reported as accurately as possible. However, any numerical value by nature contains certain errors necessarily resulting from the standard deviation found in their respective measurements. The following examples are intended to illustrate the present invention without limiting its scope. Examples

[0117] The quantities / concentrations of ingredients in the compositions / formulas described below have been expressed in % by weight, relative to the total weight of each composition / formula.

[0118] The materials not specified here were all commercially available. Example 1

[0119] Compositions A1-A2, and comparative composition B, in Tables 1 and 2, were respectively formulated:

[0121] The compositions A1, A2 and B listed above were prepared according to a manufacturing process known in the art.

[0122] Compositions A1, A2 and B were obtained in the form of a shampoo product according to the present invention. Example 2

[0123] Compositions A1, A2 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 average friction force (reported in N)) and DETANGLE test (for average disentangling force (reported in N)), according to standard procedures for both device tests. For each of the tests, a relatively lower value represented a better result. The evaluation was carried out according to the following steps:

[0124] 1) All hair strands were washed twice with the compositions cleaning agents Al, A2 and B (1.6g + 1.2g / 6g strand of hair) according to procedure RC-MCLOIP-003B;

[0125] 2) Then, the friction force was measured for all the wicks with the test TOUCHAIR in wet condition;

[0126] 3) All the strands of hair were grouped into groups with force of similar mean wet friction and its standard deviation;

[0127] 4) The wicks were respectively treated with all the products according to the standard procedures but with 2 applications (dosage: 1.6g + 1.2g);

[0128] 5) Then, the friction force was measured for all the wicks with the test TOUCHAIR in wet condition;

[0129] 6) The hair strands were dried naturally overnight and stored in a H&T chamber (23°C, 50% RH);

[0130] 7) Then the friction force was measured again for all the wicks with the TOUCHAIR test in dry conditions;

[0131] 8) All strands of hair pass through the wind in the T&H room (10 min) to generate tangles;

[0132] 9) The detangling force was measured with the Detangle test in dry condition;

[0133] 10) The hair strands were twisted in a blender with water (10s for each) to create tangles;

[0134] 11) The disentanglement force was measured with the wet Detangle test in wet condition wet.

[0135] The results are shown in Table 2 below.

[0136] [Tables2] Results Composition Al Composition A2 Comparative composition B Dry smooth (N) 1.67 1.62 2.32 Wet smooth (N) 1.94 2.24 2.2 Dry detangling (N) 10.53 7.83 4.07 Wet detangling (N) 2.92 4.5 5.16

[0137] Referring to Table 2, it was observed that compositions A1 and A2 exhibited relatively better performances than composition B.
