Description

Cosmetic composition comprising a polymer and a surfactant The present invention relates to cosmetic compositions comprising one or more hybrid polymers comprising one or more synthetic polymer units comprising repeating units of the structure of formula (1) and one or more surfactants 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 amphoteric surfactants. Cosmetic compositions such as shampoos, hair conditioners, hair rinses, body washes, shower gels, hand washes, bubble baths, facial washes, cleansing masks, make-up removers, soaps, or cleansing foams typically contain surfactants and rheology modifiers. However, certain surfactants are not compatible with certain rheology modifiers. For example, certain surfactants, particularly certain ionic surfactants, may reduce the stability and thus the storage properties of thickened cosmetic compositions. Some rheology modifiers (e.g., xanthan gum) have limitations in stabilizing complex formulations containing oil, pearlizing agents, and cationic ingredients. Increasing the concentration for better stability is generally not a viable option, as this will have a negative impact on the texture (stringing, gelling, etc.). The customer is therefore forced to use non-biodegradable carbomers. In general, there is a need for cosmetic compositions that are stable and easy to store. Furthermore, there is a need for cosmetic compositions containing biodegradable ingredients. It is particularly challenging to provide stable and easy to store cosmetic compositions containing surfactants (including ionic surfactants) and biodegradable rheology modifiers. Accordingly, there is a need for cosmetic compositions containing biodegradable rheology modifiers that are compatible with a variety of surfactants, including ionic surfactants. Surprisingly, it has been found that certain hybrid polymers are capable of effectively thickening cosmetic compositions containing various surfactants. Accordingly, the present invention relates to a cosmetic composition comprising: (A) One or more of the hybrid polymers are used, the hybrid polymer comprises: (a-i) one or more synthetic polymer units comprising: (a) A repeat unit of the structure of formula (1): Wherein the method comprises the steps of R 1 and R 2 are independently selected from H, methyl or ethyl; A is a linear or branched C 1-C12 alkyl radical, and Q + is a cosmetically acceptable cation, and (B) Optionally one or more crosslinking or branching units, and (C) Optionally one or more other repeating units which are different from the repeating units of formula (1) and from the crosslinking or branching units, and (A-ii) one or more water-soluble and/or water-swellable polysaccharide polymer units, and (B) One or more surfactants selected from the group consisting of anionic surfactants, cationic surfactants, nonionic surfactants, zwitterionic surfactants and/or amphoteric surfactants. Advantageously, the cosmetic compositions of the present invention are stable and storable. Unless otherwise indicated, all percentages are weight percentages (w/w) of the respective compositions to which they relate. The term "wt%" refers to weight percent. All ratios are weight ratios. Unless specifically stated otherwise, "molecular weight" or "m.wt." or "MW" and grammatical equivalents refer to weight average molecular weight. Number average molecular weight M n The number average molecular weight is the statistical average molecular weight of all polymer chains in the sample and is defined by the formula: Where M i is the molecular weight of the chain and N i is the number of chains of that molecular weight. M n can be predicted by the polymerization mechanism and measured by a method of determining the number of molecules in a sample of a given weight, for example by a numerical method such as end group assay. If M n is referenced for a molecular weight distribution, the number of molecules on either side of M n in the distribution is equal. Weight average molecular weight M w The weight average molecular weight is defined by the formula: In contrast to M n, M w takes into account the molecular weight of the chain when determining the contribution to the average molecular weight. The larger the chain, the greater the contribution of the chain to M w. The polydispersity index PDI is used as a measure of the width of the molecular weight distribution of the polymer and is defined by the formula: The larger the PDI, the broader the molecular weight distribution. Wherein all monodisperse polymers of equal chain length have M w/Mn = 1. Unless otherwise indicated, "viscosity" is measured using an RV Brookfield viscometer at 25 ℃ with a torque of 10% to 90% and a rotation speed of 20RPM, in centipoise (cP) (=millipascal seconds (mPas)). The rheolo
