Definitions

  • the present invention relates to rinsable, skin conditioning compositions. More particularly it relates to skin conditioning compositions comprising high internal phase emulsions substantially free of surfactant.
  • Skin conditioning compositions that provide moisturizing benefits are known. Many of these compositions are aqueous systems comprising an emulsified conditioning oil or other similar material stabilized with surfactant. Typically, skin moisturizing compositions are in the form of lotions meant to be applied to the skin after bathing and throughout the day if reapplication is necessary.
  • Skin is made up of several layers of cells, which coat and protect the keratin and collagen fibrous proteins that form the skeleton of its structure.
  • the oute ⁇ nost of these layers referred to as the stratum corneum, is known to be composed of 25nm protein bundles surrounded by 8nm thick layers.
  • Anionic surfactants and organic solvents typically penetrate the stratum corneum membrane and, by delipidization (i.e. removal of the lipids from the stratum corneum), destroy its integrity. This destruction of the skin surface topography leads to a rough feel and may eventually permit the surfactant or solvent to interact with the keratin, creating irritation.
  • compositions which will effectively deposit moisturizers and /or other skin benefit agents in the shower and/or bath and thereby assist the stratum corneum in maintaining its barrier and water-retention functions at optimum performance in spite of deleterious interactions which the skin may encounter in washing, work, and recreation.
  • Desirable properties of such skin care compositions are to provide good skin feel, water retention, moisturization, absorption, and rub-in characteristics.
  • One way of delivering high moisturization to the skin is to incorporate polyhydric alcohol-like humectant materials such as glycerine into a composition. Skin compositions with high levels of polyhydric alcohols and therefore high levels of moisturization when left-on the skin, however, are readily rinsed away in the shower and/or bath by the consumer.
  • An alternative way of delivering desirable benefits to the skin is to incorporate oil-soluble skin care ingredients such as petrolatum into skin care compositions.
  • compositions which incorporate the oil as an oil-in-water emulsion, must stabilize the emulsion which is generally done with surfactant (typically nonionic surfactant for lotions and anionic or amphoteric surfactant for lathering products). Again, such compositions when stabilized with surfactant, deposit poorly on the skin due to emulsification of the oil by the surfactant.
  • surfactant typically nonionic surfactant for lotions and anionic or amphoteric surfactant for lathering products.
  • the need remains for a rinsable, skin-conditioning composition that can provide improved conditioning and other skin care benefits to human skin. Additionally, there remains a need for a rinsable, skin-conditioning composition which exhibits pleasing tactile properties and increased deposition of skin conditioning and/or skin care agents. The need also remains for in-shower and/or bath lotion compositions which show low levels of stickiness or tackiness whilst providing high levels of moisturization, as well as providing excellent skin feel, skin softness and skin smoothness benefits.
  • compositions comprising high internal phase oil- in-water emulsions show excellent oil deposition, excellent moisturization benefits, with low levels of stickiness or tack and superior product stability. These compositions can be formulated at surprisingly high viscosities while maintaining excellent spreadability on wet skin. The compositions also show good skin feel, skin softness and skin smoothness benefits. Other benefits in using high internal phase emulsions are that they are very easy to manufacture, they give the formulated great control over oil droplet size, they are low irritating and they allow for emulsification of previously incompatible materials in the same product. These and other benefits will be discussed in greater detail below.
  • the present invention provides rinsable, skin-conditioning compositions, which may further comprise skin benefit agents. These compositions provide improved aesthetics and skin feel during and/or after application, and are especially useful in providing improved deposition or effectiveness of skin conditioning agents to the desired area of the skin. The benefits of the compositions of the present invention are further improved
