Description
Technical Field
The present invention relates to compositions for conditioning keratin materials, in particular the skin, the scalp or the hair together with the scalp. The invention also relates to a method for conditioning keratin materials, in particular the skin, the scalp or the hair together with the scalp, using the composition according to the invention.
Background
Keratin materials are widely found on human surfaces such as skin, scalp and hair. For a long time, many people have sought a fresh body surface to feel comfortable in daily life and work. Among them, many are particularly concerned with the sticky/greasy feel. Accordingly, various products have been developed to cope with the sticky or greasy feeling of humans.
Among keratin materials on the body surface, the scalp is particularly vulnerable to oils and fats. Various formulations have been developed for use with sticky or greasy scalp, including those provided in separate forms, such as lotions, sprays, and the like, as well as those incorporated into conventional products for use with hair and/or scalp, such as shampoos, leave-in and/or rinse-off conditioners.
Various conditioning compositions have been developed primarily for use with hair, which are generally used to improve or restore the natural luster, shine, smoothness and softness of hair. When used in the context of shampooing, a commonly accepted method of conditioning hair is shampooing, then rinsing the hair, and then applying the conditioner composition, optionally followed by a second rinse.
Thus, there remains a need in the art to develop new compositions for caring for primarily the scalp, especially without a greasy feel.
Disclosure of Invention
Silica is known for use in cosmetics, for example as a conventional filler, or as a matrix for absorbing lake dyes. Derivatives of silica and/or modified silica are also used. However, any effect on (modified) silica to address the greasy state of keratin materials is unknown in the art. Through intensive studies, the present inventors have surprisingly found that by using a specific modified silica in a specific form (in particular modified in terms of both structure and chemical bonds), sebum migration on keratin materials, in particular on the scalp, and thus the greasy feel, can be effectively inhibited.
Accordingly, one subject of the present invention is a leave-on composition for conditioning keratin materials, comprising:
spherical particles of lipophilic modified silica uniformly dispersed in a medium/solvent;
at least one cationic polymer, and
at least one thickener.
The composition according to the invention is particularly useful for conditioning keratin materials, for example, in particular for scalp care. Thus, the compositions of the present invention may be in various forms, e.g., lotions, creams, sprays, etc., for direct application to the scalp, application to the skin, or application to the hair along with the scalp.
Embodiments of the invention
Throughout the specification, including the claims, the term "comprising" is to be understood as synonymous with "including at least one" unless otherwise indicated. Furthermore, the expression "at least one" as used in the present specification is equivalent to the expression "one or more".
Throughout the specification including the claims, embodiments defined by "comprising" and the like should be understood to include preferred embodiments defined by "consisting essentially of …" and preferred embodiments defined by "consisting of …".
Except in the operating examples, or where otherwise indicated, all numbers expressing quantities of ingredients and/or reaction conditions are to be understood as being modified in all instances by the term "about," having a meaning conventionally known in the art, such as within 10% of the indicated number (e.g., "about 10%" represents 9% -11% and "about 2%" represents 1.8% -2.2%).
Throughout the specification, including the claims, a "keratin material" according to the present invention is skin, hair, scalp, eyelashes, eyebrows, body hair, nails, lips, or mucous membranes. Preferably, the keratin materials according to the invention are locations which are susceptible to a sticky or greasy feel, such as the scalp or the skin, and/or locations on which a sticky or greasy feel has an effect, such as the hair.
Throughout the specification, including the claims, "care" and the like according to the present invention should be understood to encompass any means of caring for, maintaining or improving the condition of keratin materials, including not only conventional means of caring for keratin materials such as the skin or scalp, but also any means known to be useful for conditioning and/or cleansing keratin materials such as the hair or scalp.
In this application, unless explicitly mentioned otherwise, amounts, parts and percentages are expressed on a weight basis.
The present invention relates to a composition for caring for keratin materials, comprising:
(A) Spherical particles of lipophilic modified silica uniformly dispersed in a medium/solvent;
(B) At least one cationic polymer comprising a cationic cellulose polymer (B-1); and
(C) At least one thickener comprising a refreshing thickener (C-1) selected from vinyl polymers.
The present invention thus provides the use of spherical particles of lipophilic modified silica for alleviating the greasy feel of keratin materials on the body surface, in particular the scalp.
Other features and advantages of the present invention will become more apparent upon reading the following description and examples.
Spherical particles of lipophilic modified silica (A)
The composition of the present invention comprises spherical particles of the lipophilic modified silica (a).
According to the present invention, "spherical particles" refer to particles that are spherical or at least approximately spherical, and/or particles that have an aspect ratio of about 0.9 to 1.1, for example about 0.95 to 1.05. For example, one skilled in the art can determine whether the particles are spherical based on conventional knowledge. In particular, for a given silica, one of ordinary skill in the art can distinguish spherical shapes from other shapes of plates, rods, powders, bars, irregular shapes, etc., and from amorphous analogs.
According to the present invention, silica needs to be in a "homogeneously dispersed" state. For example, the formation of dispersions, emulsions, solutions, etc. having definitions and/or standards known in the art may represent the achievement of a "uniformly dispersed" state. Nevertheless, it should be appreciated that once one of ordinary skill in the art can determine that a state is significantly different from a "non-uniformly dispersed" state, the state may be considered to substantially satisfy the "uniformly dispersed" state.
According to the invention, "lipophilically modified" silica refers to silica that has been lipophilically modified. According to the invention, lipophilic modification refers to any organic modification capable of hydrophobic or lipophilic treatment of silica. For example, the silica may be treated with a siloxane compound, such as hydroxydimethylsiloxane (or other silane, such as silazane, etc.), by which the silica surface is treatedThe silanol groups of the above and silanol groups of the silicone compound undergo condensation. Among these, usable examples of "lipophilic modified" silica may be silylated silica and dimethylsilylated silica, such as silylated silica, which may be named for example
TL-10 is a silylated silica available from TOKUYAMA CORPORATION company.
According to the present invention, the spherical particles of the lipophilic modified silica may exhibit an oil absorption capacity of 500ml/100g or more, 600ml/100g or more, or even 700ml/100g or more when incorporated into the composition.

Method and use
The composition according to the invention may be generally prepared according to the general knowledge of a person skilled in the art. However, it will be appreciated that the person skilled in the art may choose the preparation method based on his/her general knowledge, taking into account the nature of the components used, e.g. their solubility in the carrier, and the intended application of the composition or kit.
According to one embodiment, the composition according to the invention can be used for caring keratin materials, in particular the scalp, or the hair together with the scalp. The use may be represented by a method for caring for keratin materials, in particular the skin, the scalp and/or the hair, comprising a step of applying to said keratin materials a composition according to the invention.
The composition according to the invention is preferably used for formulating hair conditioner products, scalp care products or even skin care products. Furthermore, from the detailed discussion above, it should be understood that the compositions according to the present invention, and thus the conditioner product and/or shampoo product, may be free of silicone oil.
The keratin fiber conditioning composition of the present invention can be used in the form of leave-on products and can be formulated into a variety of product forms including, but not limited to, creams, lotions, gels, emulsions, mousses and sprays.
The keratin fibre conditioning composition as described above can be used to condition keratin fibres such as the hair together with the scalp by conventional means, depending on the form of application of the composition.
For example, when used as leave-on conditioning agents after shampooing, the compositions of the present invention may be applied by a method comprising the steps of:
(i) Shampoo; and
(ii) An effective amount of the composition is applied to hair for conditioning the hair without further rinsing the hair.
The invention will be further illustrated by the following examples, which illustrate particularly advantageous embodiments.
Notwithstanding that the numerical ranges and parameters setting forth the broad scope of the invention are approximations, 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. The following examples are intended to illustrate the invention without, however, limiting the scope.
Examples
The amounts/concentrations of ingredients in the following compositions/formulations are expressed in weight percent relative to the total weight of each composition/formulation.
Materials:
silylated silica: available from TOKUYAMA CORPORATION
TL-10, spherical particles of lipophilic modified silica;
other materials not described herein are each commercially available.
Example 1
Preparation of compositions a and a':
TABLE 1
The above composition a is prepared according to the preparation methods known in the art.
6 volunteers used composition A and evaluated the refreshing sensation brought about by composition A, with less greasy sensation of the roots and with a marked bulge of roots than the control without addition of either component (B) or (C).
Example 2
The effect of the composition on grease inhibition was determined using a sebum migration test, comprising the steps of:
step 1: the hair samples were rinsed with standard shampoo DOP and with test product according to the known procedure RC-MCI-OIP-003B
Step 2: 100 μl of colored artificial sebum (red) was applied over a selected 3cm area of the top area of the hair sample.
Step 3: the hair samples were hung on an iron stand at 30℃and 50% humidity.
Step 4: images of hair samples were taken at 1 hour, 2 hours, 4 hours, 6 hours and 24 hours.
Step 5: the total sebum migration area was calculated at each time point using image analysis.
Sebum migration results are provided below:
TABLE 2
For the sebum migration test, a smaller sebum migration area means more inhibition of grease. Thus, it is clear that the comparison a' using lipophilic modified silica spherical particles uniformly dispersed in a medium/solvent can bring about high grease inhibition, which is reflected by a low sebum migration area. It was observed that even lower sebum migration areas were generated when composition a was used.
Example 3
6 volunteers 25-45 years old were allowed to apply composition a daily to the hair and scalp for 3 days. The score for the sticky or greasy feel after administration of composition a was given daily with the score for the sticky or greasy feel before administration of composition A B as baseline and the average score is shown in table 3.
Volunteers gave a score for a greasy feeling, wherein:
0 represents unchanged;
1 means general improvement;
2 means a significant improvement; and
3 indicates substantially no greasy feel.
The average scores of 6 volunteers were regarded as the immediate status, 24 hours and 48 hours, and the average per day was calculated. The average score for a total of 3 days is provided in table 3 below.
TABLE 3 Table 3
Note that: for convenience, each average score in table 3 is rounded to an integer.
Referring to table 3, the lower the score, the less sticky or greasy feel. Composition a was observed to exhibit a very good and long-term anti-tack or anti-greasy feel.
