Description

Personal Care Compositions

In the field of hair care, for example, styling is generally achieved by the application of permanent chemically modified products or temporary styling products. Permanent chemically modified products, often referred to as "hair perm", typically involve treating the hair with various sulfur-containing compounds in order to be able to change the shape and orientation of the hair fibers by breaking the disulfide bonds of the hair fibers. However, hair permeable products have the disadvantage of roughening and damaging hair, long lasting and difficult to return. In contrast, temporary styling products generally do not break the chemical bonds of the hair fibers. These temporary styling products are typically in the form of gels, lotions, mousses or sprays containing polymeric resins or rubbers for coating hair fibers and bonding the fibers together. Many temporary styling products are inconvenient to use, have the disadvantage of not being able to easily restyle the hair after the first application, and the styling is completed without further application of additional products. It is desirable to deliver styling and fixing benefits using cleaning products such as conditioners and shampoos. However, these types of cleaning products require styling agents that are firm to the hair and are not easily removed during the cleaning process. Particularly useful styling and immobilizing agents in cleaning compositions are hydrophobic polymeric materials. However, the hydrophobic material may cause accumulation of visible unsightly residues on the hair by repeated use. These residues can eventually completely surround the hair and become difficult to remove with a normal shampoo. Therefore, there is a need for an improved composition to provide temporary styling and fixation of human hair without residues and often disadvantages associated with the composition. Similarly, there remains a need for film-forming skin compositions that are easily washed with soap and water.

Surprisingly, hair care products comprising copolymers having at least one acid functional monomer and at least one nitrogen containing functional monomer and a copolymer complex comprising at least one fatty acid complexed with a nitrogen containing functional monomer are in addition to improved “wash” properties. It has been found to provide excellent temporary styling and fixing advantages. The copolymer complexes of the present invention are soluble or dispersible in hydrophobic solvent components and are easily deposited by the solvent components and are also easily washed by the aqueous surfactant solution. These compositions may be prepared in any of a number of conventional forms, including but not limited to shampoos, conditioners, mousses, gels, lotions, sprays, and the like.

In addition to the hair care benefits described above, the copolymer complexes and volatile hydrophobic solvent components of the present invention have also been found useful for incorporation into a wide variety of cosmetic and pharmaceutical compositions for topical application to the skin. These materials spread more easily and evenly on the skin, give a good feel to the skin and provide very robust topical compositions. In addition, these compositions are useful for providing a barrier for increasing the penetration of a wide variety of cosmetic and pharmaceutically active substances into the skin or through the skin for systemic delivery.

Compositions of the present invention comprise copolymer complexes and volatile hydrophobic solvent components suitable for application to hair or skin. Copolymer complexes include copolymers having one or more nitrogen containing functional groups and one or more fatty acids complexed with nitrogen containing functional groups.

Essential ingredients

The compositions of the present invention comprise copolymer complexes and volatile, hydrophobic solvent components suitable for application to hair and skin, wherein the copolymer complexes comprise copolymers complexed with fatty acids.

Copolymers of the invention may comprise graft copolymers. The term “graft copolymer” is familiar to those skilled in the art of polymer science, and herein a polymeric chemical moiety (ie, “graft”) is added or added onto another polymer moiety, often referred to as the “backbone”. Used to describe copolymers produced by "grafting". The backbone typically has a higher molecular weight than the graft. Thus, graft copolymers can be described as polymers having pendant polymer side chains, and can be described as being formed from "grafting" or incorporation of polymer side chains on or within a polymer. The polymer into which the graft is incorporated may be a homopolymer or a copolymer. Graft copolymers are derived from various monomeric units.

Copolymers of the invention can be prepared from the copolymerization of monomeric units and macromonomer units such that they are "grafted" or incorporated into the copolymer from which the macromonomer units are produced. The term "macromonomer" is a term familiar to those of ordinary skill in the polymer sciences and is used to describe polymeric materials containing polymerizable moieties. That is, the macromonomers are macromolecular monomers that are essentially high molecular weight type monomer forming block units that can be used in polymerizations to form polymers with themselves, or with other monomers, or with other macromers.

The term "hydrophilic" is used herein consistent with its standard meaning of having affinity for water, while "hydrophobic" is used herein consistent with its standard meaning of lacking affinity for water. Used. "Hydrophilic" as used herein in the context of monomeric units and polymeric materials, including macromers, copolymers, and solvents for copolymers, means substantially water soluble. "Substantially water soluble" refers to a substance which is dissolved in distilled water (or equivalent water) at a concentration of 0.2% by weight at 25 ° C, preferably at 1.0% by weight. In contrast, "hydrophobic" means substantially water-insoluble. In this context, "substantially water-insoluble" refers to a substance which does not dissolve in distilled water (or equivalent water) at a concentration of 0.2 ° C. at 25 ° C. and preferably does not dissolve at 0.1% by weight.

As used herein, the term “soluble” or “solubility” means the ability of a substance to form a solution, ie a gin or colloidal solution. A gin solution is a mixture of one or more substances (solutes) uniformly dispersed at the molecular or ionic level in one or more substances (solvents). The two parts of the solution are called phases. Colloidal dispersions are often called solutions. Colloidal particles are larger than molecules, so calling this dispersion as a solution is strictly wrong; However, the term is widely used in the literature. As used herein, the term "dispersibility" or "dispersity" consists of a dispersion, i.e., finely divided particles (often within the colloidal size range) in which one phase is distributed throughout the bulk material, the particles being discontinuous phase or internal Phase and bulk material refers to the ability of a material to form a two-phase system that is a continuous phase or an external phase.

The term "wash or wash" is used herein to mean that the composition of the invention is used literally so that the composition is ultimately washed or washed from the hair and / or skin after or during the application of the product. Non-limiting examples of cleaning products of the present invention include hair conditioners, shampoos and soaps.

As used herein, the term “hard” or “hard” means that a chemical or pharmaceutically active substance is bound or maintained to the surface layer or hair of the stratum corneum.

As used herein, the term “suitable for application to human hair and skin” refers to a composition or component so described in contact with human hair and hair leather and skin without exhibiting excessive toxicity, incompatibility, instability, allergic reactions, or the like. It is meant to be suitable for use.

The foregoing definitions also apply to other materials so described herein, and to some extent any other definitions associated with these materials are consistent with those mentioned above.

The composition of the present invention comprises the following essential ingredients.

Copolymer complex

The hair and skin care compositions of the present invention comprise from about 0.25 to about 30 weight percent, preferably from about 2 to about 15 weight percent, more preferably from about 2 to about 10 weight percent, based on the weight of the hair and skin care composition. Copolymer complexes. Copolymer complexes include copolymers having at least one nitrogen containing functional monomer complexed with a fatty acid.

Copolymer

Copolymer complexes of the present invention comprise from about 35 to about 99 weight percent, preferably from about 40 to about 90 weight percent, more preferably from about 50 to about 70 weight percent of the copolymer, based on the weight of the copolymer complex. do. Based on the weight of the total hair and skin care composition, the copolymer comprises about 0.1 to about 10 weight percent, preferably about 1 to about 5 weight percent, more preferably about 1.5 to about 3.5 weight percent.

The copolymer of the present invention has a weight average molecular weight (g / mol) of about 10,000 or more. There is no upper limit to the molecular weight except where the application of the present invention is limited due to practical reasons such as viscosity, processing, aesthetic properties, blending compatibility and the like. The weight average molecular weight is generally less than about 5,000,000, more generally less than about 2,500,000, and typically less than about 1,500,000. Preferably the weight average molecular weight is from about 10,000 to about 5,000,000, more preferably from about 50,000 to about 2,000,000, even more preferably from about 75,000 to about 1,000,000, most preferably from about 75,000 to about 500,000.

The copolymer of the present invention is produced by the copolymerization of A monomer units and B monomer units which are repeated at random, preferably the A monomer is a polymerizable, ethylenically unsaturated monomer selected to satisfy the requirements of the copolymer. As used herein, "polymerizable" means monomers that can be polymerized using any conventional synthetic technique. Preferred are monomers that are polymerized using conventional free radical initiation techniques. The term "ethylenically unsaturated" is used herein to mean a monomer containing one or more polymerizable carbon-carbon double bonds (which may be mono-, di-, tri- or tetra-substituted). The B monomer unit is a hydrophilic monomer copolymerizable with A and preferably selected from polar monomers having a Tg or Tm higher than about −20 ° C., wherein at least 1% by weight of the hydrophilic B monomer of the copolymer comprises at least one nitrogen containing functional group. It is selected from hydrophilic B monomers having. The A and B monomer units form what is called the backbone of the polymer and can be selected from a wide variety of structures as long as the copolymer has the necessary properties and meets the molecular weight and other requirements described herein. The copolymers of the present invention may optionally incorporate C macromonomer units. The C macromonomer units are selected from one or more hydrophobic macromonomer units containing polymer moieties and moieties copolymerizable with A and B monomers. The C macromonomer units form hydrophobic side chains on the copolymer.

Copolymers are prepared by polymerized bonding of A and B monomers and can be characterized by the weight percent of monomers charged to the reaction vessel in which the polymerization reaction is carried out. C macromonomers may optionally be incorporated during the polymerization reaction.

As will be apparent to those skilled in the art and particularly from the examples, the copolymer may have one or more hydrophobic side chains grafted to the main chain. As is known in the art, synthetic graft copolymerization processes can produce mixtures of polymer molecules containing zero, one or more than one hydrophobic side chain covalently bonded to the polymer backbone, and pendants from the polymer backbone. From the information on the amount and number average molecular weight of the hydrophobic side chains in the polymer sample, and the number average molecular weight of the polymer sample, it is possible to calculate the average number of hydrophobic side chains per polymer backbone.

The copolymer complex of the present invention, when dried with a film having a volatile hydrophobic solvent component of 0.5% or less, has a Tg or Tm of at least about -20 ° C, more preferably at least about 20 ° C, so that the copolymer is excessive upon contact. Not sticky or "sticky". As used herein, the abbreviation “Tg” refers to the glass transition temperature of the main chain of the polymer when a transition exists for a given polymer, and the abbreviation “Tm” refers to the crystalline melting point of the main chain. Preferably both Tg and Tm, if any, are higher than about -20 ° C, more preferably about 20 ° C.

Graft copolymers must meet the following criteria:

(1) the polymer side chain portion is covalently bonded to the main chain portion;

(2) The number average molecular weight of the polymer side chain portion is about 1,500 to about 50,000.

The copolymer of the present invention is produced by the polymerization bond of A monomer and B monomer. C macromonomers may optionally be incorporated into the polymerization process. Copolymers can be synthesized by free radical polymers of monomers and macromers. The general principle of the free radical polymerization method is well known (see, eg, Odian, "Principles of Polymerization", 3rd Ed., John Wiley & Sons, 198-334 (1991)). When the reaction is complete, all of the desired monomers and macromonomers are placed in the reactor with a sufficient amount of mutual solvent so that the reaction viscosity is reasonable. Undesirable terminators, especially oxygen, are removed as necessary. This process is carried out by vacuum or by purging with an inert gas such as argon or nitrogen. An initiator is introduced and the reaction is raised to the temperature required for initiation to occur, assuming the use of a thermal initiator. The polymerization is typically run for hours to days as long as a high level of conversion needs to be achieved. The solvent is then removed, usually by evaporation or by addition of a nonsolvent to precipitate the copolymer. The copolymer can be further purified if desired.

As an alternative to the batch reaction, the copolymers can be prepared by semicontinuous or continuous processes. In the semicontinuous process, the monomer or macromonomer is added two or more times during the polymerization reaction. This is advantageous when the copolymer is made of several monomers which react at different rates during polymerization. The proportion of monomers added to the reaction at separate time points can be adjusted by one of ordinary skill in the art such that the polymer of the final product has a more uniform structure. That is, the polymer of the final product will have a more uniform monomer content distribution for each of the monomer types participating in the reaction.

Examples of related copolymers and methods of making them are described in US Pat. Nos. 4,693,935 (Mazurek, Sep. 15, 1987) and 4,728,571 (Clemens et al., 1988, incorporated herein by reference). It is described in detail in 3.1). Still other graft polymers are also described in US Pat. Nos. 5,166,276 and 5,480,634 (Hayama et al., November 24, 1992 and January 2, 1996); 5,061,481 (Suzuki et al., October 29, 1991); 5,106,609 (Bolich et al., April 21, 1992); 5,100,658 (Bolich et al., March 31, 1992); 5,100,657 (Ansher-Jackson et al., March 31, 1992); And 5,104,646 (Bolich et al., April 14, 1992), all of which are incorporated herein by reference in their entirety.

The copolymer composition is characterized by the amount of each monomer added to the polymerization reaction vessel, or otherwise the amount of each monomer used in a continuous or semicontinuous process.

By appropriate selection and combination of specific monomeric and macromonomer units, and by the selection of specific relative ratios of units within the ability of one of ordinary skill in the art, copolymers are frequently used in a variety of physical properties and hair care applications. It can be optimized for compatibility with other ingredients used.
