Description

Title of the invention: KERATINOUS FIBER TREATMENT COMPOSITION technical field

[0001] The present invention relates mainly to a process for treating, preferably remodeling, and more preferably smoothing, keratinous fibers such as hair. STATE OF THE ART

[0002] Reshaping keratin fibers, such as hair, by heating them with a flat iron is a popular method. It makes unruly keratin fibers more manageable, reduces volume, and improves their appearance. While this method of reshaping with a flat iron is convenient for quick styling, it is not easy to achieve a sufficiently smooth effect.

[0003] Furthermore, conventional methods of permanent remodeling using a reducing agent and an alkaline agent, as well as an oxidizing agent, with heating, can provide keratin fibers with an improved remodeling effect, but they have several disadvantages such as a long treatment time, damage to keratin fibers and a bad smell.

[0004] To date, some remodeling processes of keratinous fibers without using reducing agent and oxidizing agent have been reported.

[0005] For example, US-A-2023 / 0000742 discloses semi-permanent hair smoothing compositions in liquid form with an aqueous base, or in emulsion form with an oily phase, comprising 15 to 20% by weight of glyoxylic acid and 0.1 to 5% by weight of levulinic acid. DISCLOSURE OF THE INVENTION

[0006] There is still a need to improve the method of remodeling keratinous fibers.

[0007] An objective of the present invention is to propose an improved remodeling process for keratinous fibers such as hair, which can provide keratinous fibers with improved remodeling effects while also providing keratinous fibers with an improved texture, such as less squeaking, and better discipline of the keratinous fibers, leading to easier combing of the keratinous fibers and easier application of a hair straightener to the keratinous fibers.

[0008] The above objective of the present invention can be achieved by a process of re Modeling, preferably for smoothing keratin fibers such as hair, including the following steps:

[0051] The present invention can provide keratinous fibers, such as hair, with more durable remodeling effects. Thus, the present invention can lengthen or prolong the remodeling effects for keratinous fibers. In particular, the present invention can further maintain the remodeled shape of keratinous fibers, or can prevent or reduce the loss of the remodeled shape of keratinous fibers over time.

[0052] In addition, the process according to the present invention can provide keratinous fibers such as hair with an improved texture, such as a better smooth texture and less squeaking sensation, and better discipline of the keratinous fibers, leading to ease of combing of the keratinous fibers and ease of application of a hair straightener on the keratinous fibers.

[0169] The composition used for the present invention may have a pH of 3 to 8, preferably of 3 to 7, and more preferably of 3.5 to 6, which is measured at 25 °C.

[0170] The ingredients of composition B are described in detail below.

[0171] (c) Silicone

[0172] Composition B in the process according to the present invention comprises at least one silicone. Two or more silicones may be included in composition B. Thus, a single type of silicone or a combination of different types of silicones may be used in composition B.

[0173] In the context of the present invention, the term "silicone" used herein means, in accordance with the generally accepted definition, all organosilicon polymers or oligomers having a linear or cyclic, branched or cross-linked structure of varying molecular weight, obtained by polymerization and / or polycondensation of appropriately functionalized silanes, and essentially comprising a repetition of principal motifs in which the silicon atoms are linked to each other by oxygen atoms (siloxane bond =Si-O-Si=), the optionally substituted hydrocarbon radicals being directly linked via a carbon atom to the silicon atoms. The most common hydrocarbon radicals are alkyl radicals, in particular C1.C1 alkyl radicals, and especially methyl, fluoroalkyl, and aryl radicals, and in particular phenyl radicals.

[0174] The (c) silicone can be selected from silicone oils.

[0175] Here “silicone oil” means a silicone compound or substance which is in the form of a liquid or paste at room temperature (25 °C) under pressure mospheric (760 mmHg). As silicone oils, those commonly used in cosmetics can be used alone or in combination.

[0176] Silicones or organopolysiloxanes are defined, for example, by Walter Noll in "Chemical and Technology of Silicones" (1968), Academy Press. They can be volatile or non-volatile.

[0177] Thus, the silicone oil or oils can be chosen from volatile silicones, non-volatile silicones and mixtures thereof.

[0178] Thus, silicone oil may comprise either at least one volatile silicone oil, or at least one non-volatile silicone oil, or both at least one volatile silicone oil and at least one non-volatile silicone oil.

[0179] Volatile or non-volatile silicone may be selected from linear, branched or cyclic silicones, optionally modified with at least one organofunctional fraction or group. (c) silicone is preferably non-volatile.

[0180] For example, silicone oil may be selected from the group consisting of polydialkylsiloxanes such as polydimethylsiloxanes (PDMS), polyalkylaryl-siloxanes such as phenyltrimethicone, polydiarylsiloxanes, and organomodified polysiloxanes comprising at least one organofunctional fraction or group selected from poly(oxyalkylene) fractions or groups, alkoxy or alkoxyalkyl fractions or groups, hydroxyl or hydroxylated fractions or groups, acyloxy or acyloxyalkyl fractions or groups, carboxylic acid or carboxylate fractions or groups, acrylic fractions or groups, and oxazoline fractions.

[0181] The silicone oil or oils may be chosen from non-volatile silicones, such as polydialkylsiloxanes, polyalkylarylsiloxanes, polydiarylsiloxanes and organomodified polysiloxanes as explained above.

[0182] The molecular weight of (c) silicone, preferably polydimethylsiloxanes with trimethylsilyl terminal groups, has a weight average molecular weight (Wm) of 300,000 or more, preferably 350,000 or more, more preferably 400,000 or more, and preferably 3,000,000 or less, more preferably 2,000,000 or less, even more preferably 1,000,000 or less.

[0183] According to one embodiment, (c) silicone, preferably silicone oil, can be selected from non-volatile polydialkylsiloxanes, for example, polydimethylsiloxanes with trimethylsilyl terminal groups known by the trade name dimethicone.

[0184] The preferred (c) silicones according to the present invention may be polydimethylsiloxanes with trimethylsilyl terminal groups, such as oils having a viscosity at 25 °C greater than 1,000,000 cSt (mm² / s), more preferably a viscosity greater than 2,000,000 cSt, and even more particularly greater than 5,000,000 cSt, better still greater than 10,000,000 cSt and preferably less than 50,000,000 cSt, better still less than 30,000,000 cSt, even better still less than 15,000,000 cSt.

[0185] According to the present invention, all polydimethylsiloxanes can be used as such or in the form of solutions, emulsions, nanoemulsions or microemulsions.
