[0002] The present disclosure relates to a cosmetic composition, in particular a vegan, semi - solid, colored, and stable cosmetic composition.

Background Art

[0003] To satisfy modern customers, cosmetic compositions, for example, including mascara compositions, must meet an ever - increasing list of technical criteria, such as, in particular, being able to provide a high pigment amount, having a long - lasting aesthetic appearance and a desirable texture, and being storage - stable. It is difficult to achieve all the desired properties and may require considerable experimentation.

[0004] Complicating this problem is that as customers' interest in the origin of cosmetic raw materials increases, the number of available raw materials is decreasing. Therefore, for example, it is very difficult to be vegan while still meeting all customers' requirements.

[0097] Coating film-forming substance In some embodiments, the composition may include a coating film-forming substance (sometimes referred to as a "coating film-forming agent"). In some embodiments, the composition may include one coating film-forming substance. In some embodiments, the composition may include a plurality of coating film-forming substances. In some embodiments, the composition may include three silicone-based coating film-forming substances.

[0098] As used herein, the terms "coating-forming composition", "coating-forming agent", "coating-forming polymer", or "coating-forming resin" refer to a polymer or resin that leaves a film on the substrate on which it is applied after the solvent associated with the coating-forming composition has evaporated, been absorbed by the substrate, and / or dissipated on the substrate.

[0099] In some embodiments, the coating-forming agent may have at least one glass transition temperature (Tg) that is lower than normal human body temperature (98.6°F). In some embodiments, at least one coating-forming agent may have glass transition temperatures (plural) that are all lower than normal human body temperature (98.6°F). The Tg characteristics of at least one coating-forming agent may result from various methods known in the art, such as the Tg of the coating-forming agent itself, a combination of different coating-forming agents to achieve a Tg lower than normal human body temperature, or a combination of coating-forming agent(s) and plasticizer(s) to achieve a Tg lower than normal human body temperature. Examples of acceptable classes of coating-forming agents include acrylic polymers, silicone resins, silicone acrylate copolymers, vinyl pyrrolidone (VP)-containing homopolymers and copolymers, polyurethanes, polyolefins, and mixtures thereof.

[0100] In some embodiments, the coating-forming agent(s) may be a silicone resin, a silicone acrylate copolymer, an acrylate copolymer, or a mixture thereof. The term "acrylate copolymer" generally refers to a copolymer that includes at least one acrylate (including methacrylate) monomer. A copolymer is a polymer derived from more than one monomer, and there are bipolymers, terpolymers, quaterpolymers, etc. constructed from two, three, four different monomers, respectively. The acrylate copolymers as referred to herein may have monomers arranged in different structures such as linear, branched, and block copolymers. Thus, the acrylate copolymers may have different arrangements, but all include at least two different monomers, one of which is an acrylate monomer.

[0101] Silicone resin As used herein, the term "resin" means a crosslinked or non-crosslinked three-dimensional structure. The nomenclature of silicone resins is known in the art as the "MDTQ" nomenclature, according to which silicone resins are described according to the various monomer siloxane units that make up the polymer.

[0102] Each letter of "MDTQ" indicates a different type of unit. The letter M indicates the monofunctional unit (CH3)3SiO1 / 2. This unit is considered monofunctional because when this unit is part of the polymer, the silicone atom only shares oxygen. The "M" unit can be represented by the following structure.

Chemical formula

[0103] At least one of the methyl groups of the M unit may be replaced by another group. For example, a unit of the formula [R(CH3)2]SiO1 / 2 is obtained and represented by the following structure.

Chemical formula

[0104] The symbol D represents the difunctional unit (CH3)2SiO2 / 2. Here, the two oxygen atoms bonded to the silicon atom are used for bonding with the rest of the polymer. The "D" unit, which is the main building block of dimethicone oil, can be represented as follows.

Chemical formula

[0105] At least one of the methyl groups of the D unit may be replaced by another group. For example, a unit of the formula [R(CH33)2]SiO1 / 2 can be obtained.

[0106] The symbol T represents the trifunctional unit, (CH3)SiO3 / 2, and can be represented as follows.

Chemical formula

[0107] At least one of the methyl groups of the T unit may be replaced by another group. For example, a unit of the formula [R(CH3)2]SiO1 / 2 can be obtained.

[0108] Finally, the letter Q means the tetrafunctional unit SiO4 / 2, where the silicon atom is bonded to four hydrogen atoms, and those hydrogen atoms are bonded to the rest of the polymer.

[0109] In this way, a vast number of different silicone polymers can be produced. Furthermore, it will be apparent to those skilled in the art that the respective properties of potential silicone polymers differ depending on the type(s) of monomer(s), the type(s) of substituent(s), the size of the polymer chain, the degree of crosslinking, and the size of the side chain(s).

[0110] Non-limiting examples of silicone polymers include siloxysilicates and silsesquioxanes.

[0111] A non-limiting example of a siloxysilicate is trimethylsiloxysilicate, which can be represented by the formula [(CH3)3XSiXO]xX(SiO4 / 2)y (i.e., MQ units), where x and y may be in the range of, for example, 50 to 80. On the other hand, silsesquioxane is represented by the formula (CH3SiO3 / 2)x (i.e., T units), where x may have a value up to, for example, several thousand.

[0112] Resin MQ available from Wacker, General Electric, and Dow Corning is an example of a commercially available siloxysilicate. For example, trimethylsiloxysilicate (TMS) is commercially available under the trade name SR1000 from General Electric and under the trade name TMS 803 from Wacker.

The T resin may also contain hydroxyl groups and / or alkoxy groups. The T resin may have a total weight of hydroxyl functional groups in the range of 2% to 10% and a total weight of alkoxy functional groups of up to 20%. In some embodiments, the total weight of hydroxyl functional groups may be in the range of 4% to 8% and the total weight of alkoxy functional groups may be up to 10%.

[0118] In some embodiments, the silicone resin may be selected from silsesquioxanes represented by the formula ((CH3)SiO3 / 2)x, where x may be up to several thousand, and the CH3 groups may be replaced by R groups as described above in the definition of T units. The number x of T units in the silsesquioxane may be 500 or less, or may be in the range of 50 to 500 (including all ranges and sub-ranges therebetween). The molecular weight of the silicone resin may be in the range of 500 to 50,000 g / mol, 500 to 20,000 g / mol, or 500 to 10,000 g / mol (including all ranges and sub-ranges therebetween).
