Patent Application
20080226576
Disclosed herein is a method for preventing deterioration of the feel of the hair upon repeated application of a hair shaping composition comprising at least one alkoxysilane comprising at least one solubilizing functional group, said method comprising applying to the hair said hair shaping composition, wherein said hair shaping composition further comprises at least one silicone. Also disclosed herein are cosmetic compositions comprising at least one silicone and at least one alkoxysilane comprising at least one solubilizing functional group.
People with thin and frizzed hair are seeking long-lasting hair styling effects that would add weight, body, and extra-volume to the hair.
Hair products enable a method to non-permanently reshape the hair and to obtain such hair styling effects. They may be applied onto wet or dry hair, prior to manually styling the hair or using a brush or a comb. They typically comprise at least one cosmetic active agent, such as fixing polymers, thickeners, glycerol, silicones, and waxes.
Once they have been applied onto the hair and been dried, these products may significantly harden. They thus may produce a full-bodied and dry feel required for preserving the hair shape and volume.
Such hair products also may suffer from giving styling effects to the hair that can disappear after the first shampoo following the hair product application. They hence have to be applied every day.
However, there are some hair products that can enable obtaining such hair styling effects, for example, giving weight, body, and extra-volume, whilst resisting to several shampoos.
It is known, for example, from French Patent Nos. FR 2 783 164, FR-2 783 167, FR 2 783 165, and FR 2 798 063 to use silicon organic compounds chosen from silanes comprising one silicon atom and siloxanes comprising two or three silicon atoms, these compounds being water-soluble, for preserving the hair style or the hair shape. Such compounds may make it possible to obtain hair styling effects, for example, to add weight and/or body to the hair, to make detangling easier, and to refine curl shape, while being resistant to several shampoos. However, these effects can be relatively poor and irregular and can become indistinct after about two weeks.
Cosmetic compositions are also described, for instance, in French Patent Nos. FR 552 855, FR 552 853, and FR 552 856, said compositions comprising silicon organic compounds that are soluble in alcohol-based media or in water-alcoholic-type media containing hydrolyzable and polymerizable functional groups, these compositions being able to obtain strong hair styling effects that may last throughout several shampoos.
However, after a repeated application of the hair products comprising silicon organic compounds, especially solubilizing functional group-containing alkoxysilanes, the hair may become dry and coarse, and may have a sensitized feel and/or be damaged.
Therefore, there is a need in the art for a cosmetic composition for hair shaping that enables the user to obtain strong styling effects lasting throughout several shampoos while keeping a natural hair feel.
The present inventors have found, surprisingly, that including at least one silicone in a hair shaping composition comprising at least one alkoxysilane comprising at least one solubilizing functional group can make it possible to prevent deterioration of the feel of the hair upon repeated application of said hair shaping composition.
Thus disclosed herein is a method for preventing deterioration of the feel of the hair upon repeated application of a hair shaping composition comprising at least one alkoxysilane comprising at least one solubilizing functional group, the method comprising applying to the hair said hair shaping composition, wherein said shaping composition further comprises at least one silicone.
As used herein, the term “preventing deterioration of the feel of the hair,” means preventing the hair from becoming dry and/or coarse, from having a sensitized hair feeling, and from being damaged.

Non-limiting examples of organic acids include acetic acid, propanoic acid, butanoic acid, lactic acid, glycolic acid, ascorbic acid, maleic acid, phthalic acid, succinic acid, taurine, tartaric acid, gluconic acid, glucuronic acid, and citric acid.
When at least one organic acid is present in the composition of the present disclosure, it is possible to increase the amount of water in the composition.
The composition used according to the present disclosure may be in any form that can suitably be applied onto the hair, for example, lotions, serum type solutions, gels, water-in-oil emulsions, oil-in-water emulsions, and combinations thereof, with a more or less thick, liquid consistency, such as milks and creams that are more or less creamy, and foams. Thus, the composition used according to the present disclosure may be in a form chosen from lotions, gels, foams, styling creams, treating creams, shampoos, after-shampoos, and colouring compositions.
The composition used according to the present disclosure may be conditioned in different forms, for example, in tubes, in cosmetic jars, in sprays, in pump containers, and in aerosol containers, in order to distribute the composition as a spray or as a foam.
When the composition is conditioned as an aerosol, it may be contained in a two-compartment container.
When the composition is conditioned in an aerosol device, it comprises at least one propellant, which may be chosen from volatile hydrocarbons, such as n-butane, propane, isobutane, pentane, halogenated hydrocarbons, and mixtures thereof. Additional examples of suitable propellants include, but are not limited to, carbon dioxide, nitrous oxide, dimethyl ether (DME), nitrogen, and compressed air. Combinations of propellants may also be used. According to at least one embodiment, the propellant is dimethyl ether.
The propellant may be present in the composition in an amount ranging from 5 to 90% by weight relative to the total weight of the composition within the aerosol device, for example, from 10 to 60%.
As discussed above, the composition of the present disclosure is a hair shaping composition.
For shaping the hair, the composition comprising the at least one alkoxysilane comprising at least one solubilizing functional group and the at least one silicone, is applied onto the hair, and optionally rinsed off. In at least one embodiment, the application is conducted by spraying, either via a pump bottle, or via an aerosol.
The composition of the present disclosure is then allowed to stand on the hair so as to let it penetrate into the hair, for example, for a time period of up to 30 minutes, such as from 5 to 15 minutes.
The hair may be rinsed with water after the composition is applied and allowed to react for a while.
The hair may then be set in form, for example, by means of a brush and/or an iron.
According to one embodiment, the hair is dried using a hairdryer and set in form with a brush.
During the hair drying, the at least one alkoxysilane comprising at least one solubilizing functional group and that are monomer compounds, are drying and polymerizing, thus forming materials that are neither soluble in water nor in the shampoo.
Once the hair has been set in form as previously described, it may look thicker, fuller, and more texturized, and may be easier to style.
The resulting styling effect is stronger than the one obtained with a hair shaping without applying the composition of the present disclosure.
The hair may be washed with shampoos, and then reshaped with brushing, and the same hair styling effects can be obtained. Such effects may last throughout several shampoos.
Also disclosed herein is a cosmetic composition comprising at least one silicone defined above and at least one alkoxysilane having at least one solubilizing functional group chosen from compounds of formulas (I-III).
Other than in the examples, or where otherwise indicated, all numbers expressing quantities of ingredients, reaction conditions, and so forth used in the specification and claims are to be understood as being modified in all instances by the term “about.” Accordingly, unless indicated to the contrary, the numerical parameters set forth in the specification and attached claims are approximations that may vary depending upon the desired properties sought to be obtained by the present disclosure. At the very least, and not as an attempt to limit the application of the doctrine of equivalents to the scope of the claims, each numerical parameter should be construed in light of the number of significant digits and ordinary rounding approaches.
Notwithstanding that the numerical ranges and parameters setting forth the broad scope of the disclosure are approximations, unless otherwise indicated 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.
By way of non-limiting illustration, concrete examples of certain embodiments of the present disclosure are given below.
Cosmetic compositions for hair shaping were formulated in accordance with the present disclosure.
Parts A and B were combined prior to application onto the hair.
The compositions were applied on wet hair.
Parts A and B may be also be allowed to react for 15 minutes, then the hair is rinsed off. The hair may be allowed to air dry, may be blown dry, or may be dried using flat clips.
The hair may also optionally dry without having been rinsed off. The hair may be allowed to air dry, may be blown dry, or may be dried using a flat clip iron.
Half-transient styling effects were thus obtained, as well as good cosmetic performances with regard to the feel of the hair, suppleness, and smoothness. These good performances were maintained even after a repeated application of such compositions.
