Definitions

  • the present invention generally relates to compositions and methods for treating keratinous substrates. More particularly, the present invention relates to keratinous treatment compositions having a polycarbodiimide compound, and, in the various embodiments, at least one additional active selected from one or more a carboxylic acid compound chosen from fatty acids, their salts, and mixtures thereof, a polycarboxylic acid compound other than one that is chosen from fatty acids, their salts, and mixtures thereof, and a cationic polymer, the combination of actives used for one or more of durable non-permanent shaping or for durable retention of a non- permanent shape of at least one keratinous fiber, providing protection from extrinsic damage or repair of keratinous fibers affected by heat, UV radiation/or chemical damage.
  • keratinous substrates for example, keratinous fibers such as hair, skin, nails, and lips
  • keratinous fibers such as hair, skin, nails, and lips
  • environmental conditions for example, high or low humidity or to ultraviolet radiation from the sun
  • these substrates can lose many of their desirable properties and even become damaged.
  • Keratinous fibers, especially hair are constantly exposed to harsh extrinsic conditions, such as sun, chemical damage, e.g., from detergents, bleaching, relaxing, dyeing, and permanent waving, heat, e.g., from hair dryers or curlers, and mechanical stress or wear, e.g., from brushing or grooming activities.
  • any type of hair can diminish in quality and/or quantity over time by age and/or due to factors such as natural greasiness, sweat, shedded skin cells from the scalp, pollution, dirt, and extreme humidity conditions.
  • extrinsic conditions may strip protective materials from the surface of the hair, and/or they may disrupt the organized structure of the hair fibers, called the a-structure, which may be accompanied by a decrease in the tensile strength.
  • a-structure which may be accompanied by a decrease in the tensile strength.
  • damage to hair by extrinsic factors is more evident the further the hair fiber has grown from the root, because the hair has been exposed longer to such extrinsic factors.
  • the hair has what may be called a "damage history" as it grows, i.e., the further from the root, the lower the tensile strength and the greater the breakdown in ⁇ -structure that has occurred.
  • hair care and hair cosmetic compositions which protect and enhance the appearance of hair as well as reduce the deleterious effects of adverse environmental conditions, photo-damage, and physical stress.
  • a hair fiber contains four structural units: cuticle, cortex, medulla, and intercellular cement. Robbins, C. R. Chemical and Physical Behavior of Human Hair, 3rd Edition, Springer-Verlag (1994).
  • the cuticle layers are located on the hair surface and consist of flat overlapping cells ("scales"). These scales are attached at the root end and point toward the distal (tip) end of the fiber and form layers around the hair cortex.
  • the cortex comprises the major part of the hair fiber.
  • the cortex consists of spindle-shaped cells, or macrofibrils, that are aligned along the fiber axis.
  • the macrofibrils further consist of microfibrils (highly organized protein units) that are embedded in the matrix of amorphous protein structure.
  • the medulla is a porous region in the center of the fiber.
  • the medulla is a common part of wool fibers but is found only in thicker human hair fibers.
  • the intercellular cement is the material that binds the cells together, forming the major pathway for diffusion into the fibers.
  • hair fibers display a distinct diffraction pattern when examined by wide-angle X-ray diffraction. In normal, non- stretched hair fibers this pattern is called an "alpha-pattern".
  • the alpha-pattern or a- structure of hair is characterized by specific repeated spacings (9.8 A, 5.1 A, and 1.5 A). All proteins that display this X-ray diffraction pattern are called a-proteins and include, among others, human hair and nails, wool, and porcupine quill.
  • a new X-ray diffraction pattern emerges that is called a " ⁇ -pattem", with new spacings (9.8 A, 4.65 A, and 3.3 A).
  • Damage to hair may occur in the cuticle and/or the cortex.
  • damage to hair When normal hair is damaged by heat, chemical treatment, UV radiation, and/or physical/mechanical means, myriad chemical and physical changes are induced in the hair.
  • these damaging processes have been known to produce removal or damage to cuticle scales or to cleave the thioester linkage holding the hydrophobic 18-methyl eicosanoic acid (“18-MEA”) layer to hair.
  • 18-MEA 18-methyl eicosanoic acid
  • Non-transfer and shampoo, wash or water-resistant cosmetic, hair and skin care compositions are sought which have the advantage of forming a deposit which does not undergo even partial transfer to the substrates with which they are brought into contact (for example, clothing). It is also desirable to have compositions that do not easily "run off” or wash off the skin and lips when exposed to water, rain or tears. Accordingly, a product that provides a protective barrier to the substrate that also is shampoo, wash or water resistant and non-transferable would be of benefit to the area of cosmetic products. As such, makers of cosmetic products such as hair and skin care products continue to seek materials and ingredients that can provide such benefits.
  • non- permanent hairstyles that is, those styles obtained via non-permanent shaping of the hair.
  • non-permanent styles disappear when the hair is wetted, especially when the hair is washed with water and/or shampoo or when the hair is exposed to high humidity conditions.
  • Methods for non-permanent shaping of keratinous fibers include, for example, brushing, teasing, braiding, the use of hair rollers, and heat styling, optionally with a commercially available styling product.
  • Non-limiting examples of heat styling include blow drying, crimping, curling, and straightening methods using elevated temperatures (such as, for example, setting hair in curlers and heating, and curling with a curling iron and/or hot/steam rollers and/or flat iron).
  • elevated temperatures such as, for example, setting hair in curlers and heating, and curling with a curling iron and/or hot/steam rollers and/or flat iron.
  • compositions and methods may provide for non-permanent shaping of keratinous fibers
  • most known materials e.g., film-forming agents, resins, gums, and/or adhesive polymers
  • commercially available products e.g., conventional hair sprays, mousses, gels and lotions
  • methods employing these materials and products provide.
  • many consumers desire compositions and methods that improve and preserve non-permanent curl formation or hair style.
