Description

[0001] This invention relates to cosmetic compositions comprising one or more hybrid polymers and one or more surfactants, said hybrid polymer comprising one or more synthetic polymer units comprising repeating units of formula (1).

[0002]

[0003] And one or more water-soluble and / or water-swellable polysaccharide polymer units, and the one or more surfactants are selected from the group consisting of anionic surfactants, cationic surfactants, nonionic surfactants, zwitterionic surfactants and / or zwitterionic surfactants.

[0004] Cosmetic compositions such as shampoos, conditioners, hair gels, shower gels, body washes, hand soaps, bubble baths, facial cleansers, cleansing masks, makeup removers, soaps, or cleansing foams typically contain surfactants and rheology modifiers. However, some surfactants are incompatible with certain rheology modifiers. For example, some surfactants, particularly some ionic surfactants, may reduce the stability of thickened cosmetic compositions and thus reduce their storage properties.

[0005] Some rheology modifiers (such as xanthan gum) have limitations in stabilizing complex formulations containing oils, pearlescent agents, and cationic components. Increasing the concentration to achieve better stability is generally not a viable option, as this will negatively impact the texture (stringiness, gelation, etc.). Therefore, customers are often forced to use non-biodegradable carbomers.

[0006] Typically, people require stable and easily stored cosmetic compositions. Furthermore, they also require cosmetic compositions containing biodegradable ingredients. Providing stable and easily stored cosmetic compositions containing surfactants (including ionic surfactants) and biodegradable rheology modifiers is particularly challenging. Therefore, there is a need for cosmetic compositions containing biodegradable rheology modifiers compatible with a wide range of surfactants, including ionic surfactants.

[0007] Surprisingly, certain hybrid polymers have been found to effectively thicken cosmetic compositions containing various surfactants.

[0008] Therefore, this invention relates to cosmetic compositions comprising:

[0009] (A) One or more hybrid polymers, the hybrid polymer comprising:

[0010] (Ai) one or more synthetic polymer units comprising:

[0011] (a) Repeating unit of structure (1):

[0012]

[0013] in

[0014] R 1 and R 2 Independently selected from H, methyl, or ethyl;

[0015] A is a linear or branched C1-C 12 Alkyl; and

[0016] Q + It is a cosmetically acceptable cation; and

[0017] (b) One or more optional crosslinking or branching units; and

[0018] (c) Any one or more repeating units different from the structure of formula (1) and different from the crosslinking or branching units; and

[0019] (A-ii) one or more water-soluble and / or water-swellable polysaccharide polymer units; and

[0020] (B) One or more surfactants selected from the group consisting of anionic surfactants, cationic surfactants, nonionic surfactants, amphoteric surfactants and / or amphoteric surfactants.

[0021] Advantageously, the cosmetic compositions of the present invention are stable and storable.

[0022] Unless otherwise specified, the following definitions apply as used herein: all percentages are weight percentages (w / w) of the individual compositions involved. The term "wt%" refers to weight percentage. All ratios are weight ratios.

[0023] Unless otherwise specified, "molecular weight" or "M.Wt." or "MW" and their grammatically equivalent terms refer to weight-average molecular weight.

[0024] Number average molecular weight: M n

[0025] Number-average molecular weight is the statistical average molecular weight of all polymer chains in a sample, and is defined by the following formula:

[0026]

[0027] Where M i It is the molecular weight of the chain, and N i It represents the number of chains with that molecular weight. M nIt can be predicted through polymerization mechanisms and measured by methods such as colligative methods like terminal group determination, which determine the number of molecules in a given weight of sample. If M is cited as the molecular weight distribution... n Then M in the distribution n The number of molecules on both sides is equal.

[0028] Weight-average molecular weight: M w

[0029] Weight-average molecular weight is defined by the following formula:

[0030]

[0031] With M n In comparison, M w The molecular weight of the chain was considered when determining its contribution to the average molecular weight. The larger the chain, the greater its contribution to M. w The greater the contribution.

[0032] The polydispersity index (PDI) is used as a measure of the molecular weight distribution width of a polymer and is defined by the following formula:

[0033]

[0034] A higher PDI indicates a wider molecular weight distribution. Among these, all monodisperse polymers with equal chain lengths exhibit M... w / M n =1.

[0035] Unless otherwise specified, “viscosity” is measured at 25°C using an RV Brookfield viscometer at 10% to 90% torque and a rotational speed of 20 RPM, in centipoises (cP) (= millipascals (mPas)).

[0036] The preferred rheology modifier is a thickener.

[0037] "Water-soluble" means any material that dissolves fully in water at 25°C to form a clear solution of the material in water at a concentration of 0.1% by weight. The term "water-insoluble" means any material that is not "water-soluble".

[0038] "Very little to no" or "substantially no" means that the content is less than 1%, or less than 0.8%, or less than 0.5%, or less than 0.3%, or about 0%, based on the total weight of the composition or compound.

[0039] "Cosmetic-acceptable" means that the described composition, compound, or component is suitable for use in contact with human keratinocytes without causing excessive toxicity, incompatibility, instability, allergic reactions, etc. All compositions and compoundings described herein intended for direct application to keratinocytes are limited to those that are cosmetically acceptable.

[0040] The term "derivative" may include, but is not limited to, amide, ether, ester, amino, carboxyl, acetyl, acid, salt, and / or alcohol derivatives of a given compound. In at least one embodiment, "derivatives thereof" refers to their amide, ether, ester, amino, carboxyl, acetyl, acid, salt, and / or alcohol derivatives.

[0041] The term "monomer" refers to a discrete, non-polymerized chemical structural portion that can undergo polymerization or any suitable reaction to form a macromolecule in the presence of an initiator, such as radical polymerization, condensation polymerization, addition polymerization, anionic or cationic polymerization, ring-opening polymerization, or coordination insertion polymerization. A "unit" refers to a monomer that has already polymerized, i.e., a portion of a polymer.

[0042] As used herein, the term "polymer" can be understood most broadly as a chemical substance formed by the polymerization of two or more monomers. The term "polymer" should include all synthetic materials prepared by monomer polymerization, as well as natural polymers. A polymer prepared from only one monomer is called a homopolymer. In this document, a polymer contains at least two monomers. A polymer made from two or more different types of monomers is called a copolymer. The distribution of the different monomers can be random, alternating, or segmented (i.e., block copolymers). It should be understood that the copolymer portion of a polymer can also be combined with one or more polymer unit blocks. As used herein, the term "polymer" can include any type of polymer, including homopolymers, copolymers, and block polymers.

[0043] The term “bio-based content” as used herein is reported in ASTM D6866-12 Method B (see Section 3.3.9 of ASTM D6866-12). In this document, “bio-based carbon content,” “bio-based content,” “bio-derived carbon content,” “bio-based content,” and “biomass-derived carbon” refer to the same thing and are all expressed in wt%. The term “bio-based carbon content” is used throughout this document. ASTM D6866-12 Method B laboratory results report the bio-based carbon content as a percentage of total carbon, not as a percentage of the total mass or molecular weight of the sample. Comments on the calculation of bio-based carbon content: Currently, ASTM D6866-12 Method B (see Section 9 of ASTM D6866-12) requires that the reported percentage of modern carbon (pMC) be multiplied by a correction factor of 0.95 to account for excess carbon-14 in the atmosphere due to nuclear weapons testing. However, due to excess carbon-14 in the atmosphere… 14The continued decline in CO2 has prompted a pending revision to ASTM D6866-12 Method B to update the correction factor to 0.98. For accuracy, suppliers in the art often report a new correction factor of 0.98. Generally, results with bio-based carbon content below approximately 20% are unaffected. However, for results closer to 100%, using a factor of 0.98 will result in approximately 2-3% higher bio-based carbon content compared to using a factor of 0.95. Results between approximately 20% and 90% will see an increase of 0-3%. Therefore, the term "bio-based carbon content" as used herein is defined by the following formula:

[0044] Bio-based carbon content = pMC 0.95 (%)

[0045] Massao Kunioka reviewed methods for measuring the bio-based carbon content of biomass-based chemicals and plastics in Radioisotopes, 62, 901-925 (2013).

[0046] The Renewable Carbon Index (RCI) can be determined according to ISO 16128 (e.g., ISO 16128-1:2016). Water can be excluded from the calculation.
