Definitions

  • Hair care compositions are often formulated to have multiple properties.
  • a hair conditioner may be formulated to condition hair and also may be formulated to repair hair.
  • Hair care compositions with multiple properties are attractive to a consumer in that fewer compositions need be applied to the hair to achieve a desired effect.
  • multiple ingredients are often necessary. As the number of ingredients increases, the complexity of the composition increases. The long term stability of such a composition can become compromised due to incompatibilities among the many ingredients.
  • compositions formulators are not only faced with the challenges of finding the proper ingredients to provide the desired cosmetic properties but are also faced with the challenge of manufacturing these complicated compositions.
  • Such challenges include developing production protocols to produce a composition both on a small scale for initial testing and on a large scale for commercial marketing.
  • a greater number of ingredients may translate into a greater number of manufacturing containers required, which itself translates into more time and expense to produce the composition.
  • Cosmetic compositions thus are complicated mixtures of ingredients, and with such complexity, require careful consideration when developing production protocols.
  • Hair care composition ingredients include conditioning agents, which are often positively charged compounds. Hair fibers have a net negative charge. The positive charge of the conditioning agents is attracted to the overall negative charge of the hair fibers, making the positively charged conditioning agents substantive to the hair. This substantive nature allows the conditioning agent to interact with the hair in order for the conditioning agent to provide its conditioning effect.
  • the conditioning effect can include restoring the hair fiber after damage to the hair, such as repairing split-ends.
  • Conditioning agents known in the art include quaternary ammonium nitrogen compounds, known as “quats,” and polymers comprising moieties of such compounds, known as “polyquats.”
  • the polyquats include polyquaternium-28, a
  • PVMMA methylvinylether/maleic acid copolymer
  • PEC polyelectrolyte complex
  • the stability of PECs may be compromised due to the presence of other ingredients, especially charged compounds and polymers that could disrupt the PEC structure.
  • the usefulness of PECs may be limited by their compatibility with other ingredients that may be desirable to include in a hair care composition. Since multiple properties are often desired in hair care compositions, it would be desirable to formulate hair care compositions that include stable combinations of PECs with other hair care ingredients that provide additional desirable properties.
  • PVMMA:polyquat-28 PECs consist of only two component ingredients
  • the method of producing these PECs is described in the ISP Investments applications as comprising two or three separate containers. Such a method is cumbersome, especially in view of any additional containers required to incorporate additional ingredients. The dedication of two or three containers in a large-scale production facility for the making of one complex is inefficient and costly.
  • a consumer purchases hair care products
  • the consumer does so based on the properties of the hair care product.
  • a consumer with frizzy hair may purchase a product to de-frizz the hair
  • a consumer with split-ends may purchase a product to repair the split-ends.
  • consumers may purchase hair care products having properties desirable for a particular hair type or hair problem.
  • One method is to use still photography, such as described in the ISP Investments applications. However, additional methods are needed.

  • the present invention is predicated on the surprising and unexpected discovery of stable compositions containing polyelectrolyte complexes (PECs) and other hair benefit agents, particularly charged species, wherein the PECs remain intact and exhibit hair repair efficacy. It was unexpectedly found that the PECs can be combined with other charged hair benefit agents, such as, e.g., cationic conditioning agents, without disrupting the complex that defines the PEC structure. Due to this unexpected discovery, the present invention provides compositions that not only provide the hair mending effect of PECs but also provides the advantages of other hair benefit agents, such as, e.g. , charged hair benefit agents, e.g. , quaternary ammonium salts, cationic conditioning polymers, and the like.
  • PECs polyelectrolyte complexes
  • other hair benefit agents particularly charged species
  • Suitable hair benefit agents that can be combined with PECs in accordance with the present invention include, for example, stearamidopropyl dimethylaniine, polyquaternium-37, polyquaternium- 7, polyquaternium-39, DC 5-71 13 (silicone quaternium-16 and undeceth-1 1 and butyloctanol and undeceth-5), Abil ® T Quat 60 (silicone quaternium-22), quaternium-80, Merquat ® 2001 (polyquaternium-47), and acrylic acid/VP crosspolymer.

  • the process of the present invention also allows for the production of PECs of the same particle size distribution as those prepared using conventional processes requiring two or more separate containers.
  • the present invention provides a more efficient and cost effective process for manufacturing PECs and hair care compositions containing PECs.
  • the present invention also allows for concentrations of PECs greater than 4 wt. %, e.g., 8 wt. %.
  • the present invention has the advantage of providing methods that can graphically demonstrate the benefits of a hair care composition such that the benefits can then be effectively communicated to consumers. Consumers purchase hair care products based on the properties of the hair care products. Effectively communicating to these consumers the beneficial properties of a hair care product composition, then, is very important so that the consumers can make informed purchasing decisions when comparing competing hair care products.
  • the present invention further has the advantage of providing a test method that allows for showing improved results of split-end mending of a hair care composition such that the benefits of the hair care composition can then be effectively communicated to consumers.
  • Most split-end mending test methods use virgin hair where the split-ends are mechanically induced. It is likely that virgin hair is used in order for the ingredients of a split-end mending composition to act solely on the mechanically induced damage. In other words, in virgin hair, there is no other damage to the hair besides the split-ends. Therefore, the mending composition directs its mending capabilities only to the split-end damage. The mending ingredients of such a composition, then, would not be wasted on other parts of the hair.

Without being bound to any particular theory, PECs are believed to be substantive to the hair fiber and adhere the ends of a split-end together through adhesive properties. The positive charges of the polyquat-28 polymer are attracted to the negatively charged hair fibers and are substantive to the hair. Since the negatively charged PVMMA polymer is complexed to the polyquat-28, the PVMMA also is drawn to the hair. The ends of the split-end are then adhered together through the adhesive action of multiple PECs interacting with the ends of the split-end and/or each other (e.g., in film-formation where the film contracts while drying). Additionally, the surface tension experienced by the ends of the split-end due to the interaction of water during film-formation assists in adhering the ends together.
