Technical Field

The present disclosure relates to compositions for use on keratinous materials. It particularly relates to compositions and methods for hair styling.

Background

Compositions for hair styling are known, such as hair spray compositions, hair gels and mousses, hair volumizing compositions, hair smoothing creams, lotions (lotions), essences, oils, clays, and the like. The goals of many hair styling compositions include maintaining or fixing hair in a particular shape, providing or increasing hair volume, smoothing hair, and/or reducing or eliminating frizzy (frizz) appearance.

Existing hair styling products typically comprise a water-soluble film-forming polymer. Depending on the chemical composition of these polymers, they may be soluble in water, or they may be water-insoluble polymers, which are rendered soluble in water by various chemical modifications, such as neutralization. Solutions containing these polymers tend to be viscous and generally increase in viscosity rapidly as the concentration of the polymer increases. In styling applications, the polymer solution becomes thicker on the hair surface as the solvent evaporates to produce a sticky or tacky film. These products also tend to exhibit problems with product spreadability, hair manageability, and moisture resistance, which is particularly problematic in hot and humid environments.

In particular, while previous compositions comprising latex polymers may provide grooming properties (clean properties) to the hair due to their anionic nature, the grooming properties may mean that the product is difficult to apply and/or distribute, absorbs quickly, dries, and/or may generate static electricity in the hair. The presence of film formers may also leave the hair with a stiff, brittle, and/or greasy feel. Typically, other ingredients and conventional silicones can be used in combination with the latex polymer to overcome the brittle and hard feel caused by the use of latex polymers in hair compositions. However, this tends to leave the hair feeling greasy and it remains challenging for manufacturers to incorporate new ingredients into the composition as this may adversely affect performance, certain cosmetic attributes, texture and formulation stability. Alternative conditioning agents, such as nonionic silicones and humectants, can actually plasticize the film produced from the product, thus affecting its high humidity curl retention and forming a build-up (fringing build up), which allows the hair to sag.

There is therefore a need for new hair styling products that address one or more of these problems.

Detailed description of the invention

One aspect of the present invention relates to a hair styling composition comprising:

b. at least one acid; and

In some embodiments, the alkoxysilane is neutralized with the at least one acid.

Also disclosed herein are methods of controlling frizz comprising applying a composition according to the present disclosure to hair.

However, it should be noted that the compositions and films according to the present disclosure, as well as the hair to which the compositions or films are applied, may not have one or more of the properties mentioned herein, but still fall within the scope of the present disclosure.

It is to be understood that both the foregoing description and the following examples are exemplary and explanatory only and are not to be construed as limiting the present disclosure. Further, it should be understood that various elements and/or features of the different embodiments herein may be combined with each other. It is therefore to be understood that numerous modifications may be made to the illustrative embodiments and that other arrangements may be devised without departing from the scope of the present disclosure. Other embodiments will be apparent to those skilled in the art from consideration of the present disclosure and practice of the various exemplary embodiments disclosed herein.

It is also to be understood that the terms "the," "an," or "an" as used herein mean "at least one" and should not be limited to "only one," unless expressly indicated to the contrary. Thus, for example, use of "a surfactant" means at least one surfactant unless the context clearly dictates otherwise.

It should be understood that all patents and published patent applications cited are incorporated herein in their entirety.

Although the conjunction "comprising" may be used to disclose various features, elements or steps of a particular embodiment, it is understood that alternative embodiments are contemplated, including those described using the conjunction "consisting of …" or "consisting essentially of …". Thus, for example, implied alternative embodiments to a process comprising a + B + C include embodiments wherein the process consists of a + B + C and embodiments wherein the process consists essentially of a + B + C. As stated, the phrase "at least one of A, B and C" is intended to include "at least one a or at least one B or at least one C" as well as "at least one a and at least one B and at least one C".

All ranges and amounts given herein are intended to include subranges and amounts using any disclosed point as an endpoint. Thus, the range "1% to 10%, such as 2% to 8%, such as 3% to 5%" is intended to include the ranges "1% to 8%", "1% to 5%", "2% to 10%", and the like.

All numbers, amounts, ranges, and the like are intended to be modified by the term "about," whether or not expressly stated. Similarly, a given range of "about 1% to 10%" is intended to modify the 1% and 10% endpoints with the term "about".

Unless explicitly stated otherwise, it is not intended that any method set forth herein be construed as requiring that its steps be performed in a particular order. Accordingly, if a method claim does not explicitly recite an order to be followed by its steps or it is not otherwise explicitly stated in the claims or descriptions that the steps are to be limited to a specific order, it is not intended that any particular order be inferred.

It is to be understood that compositions according to various embodiments of the present disclosure form a film when applied to a substrate. However, the various properties of the films described herein are intended to include any film provided by the compositions according to the present disclosure, whether or not the film is adhered or bonded to a substrate. By way of example only, once the composition is applied to a substrate and formed into a film, the film may be subsequently removed to evaluate properties such as strain and young's modulus.

Unless 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 following specification and attached claims are approximations that may vary depending upon the desired properties sought to be obtained by the present disclosure. For example, the term "about" can mean within 10% of the indicated value (e.g., "about 10%" means 9% -11% and "about 2%" means 1.8% -2.2%), such as within 9%, 8%, 7%, 6%, 5%, 4%, 3%, 2%, or 1% according to various embodiments.

Notwithstanding that the numerical ranges and parameters setting forth the broad scope of the disclosure are approximations, the numerical values set forth in the specific examples are reported as precisely as possible unless otherwise indicated. Any numerical value, however, inherently contains certain errors necessarily resulting from the standard deviation found in their respective testing measurements. The following examples are intended to illustrate embodiments of the present disclosure, but are not intended to be limiting.

It is to be understood that when amounts of components are given, amounts of active materials are meant to be expressed, unless otherwise indicated.

The compositions and methods according to the present disclosure may comprise, consist of, or consist essentially of the elements and limitations described herein, as well as any additional or optional ingredients, components, or limitations described herein or known in the art.

Examples

The following examples are intended to be non-limiting and merely illustrative of the scope of embodiments of the present disclosure. The amounts of the ingredients in the compositions/formulations described below are expressed in weight%, based on the total weight of the composition.

Several formulations were prepared having the ingredients listed in the table below. If the term "neutralized APTES" appears, a 20% active APTES solution was prepared using 2.125% phosphoric acid and 3.6% lactic acid (fully neutralized). The balance of all formulations was water.
