The present invention describes, in one aspect, the use of two oppositely charged surfactants as the primary emulsifiers in two separated parts of a product. The emulsifiers are chosen such that when the two parts of the emulsion product are mixed, the emulsifiers react to form water insoluble compounds that are no longer able to function as emulsifiers, thus, the oil phase of the emulsion is precipitated onto the skin along with the emulsifier reaction product. Since none of the deposited materials are water soluble, or capable of functioning as emulsifiers, the deposited oil phase is extremely resistant to being washed off. This technology finds applications in hand and body creams and lotions, baby care products, sunscreens, skin protective products, makeup systems, and automotive and furniture polishes.

Two component interactive emulsion product

The invention describes the unexpected characteristics of blends, including crosslinked reaction products of elastomeric silicone polymers with various polyurethanes and their applications in personal care products.

The instant invention relates to novel surfactant-free, multiphase sunscreen compositions that provide protection from the sun, have a unique visual appeal, and provide skin conditioning and moisturization. In a two-phase embodiment of the instant invention, the compositions are comprised of (1) a first layer comprising a high-density ester and sunscreen, and (2) a second aqueous layer, which is usually the top layer. In a three-phase embodiment of the instant invention, the compositions are comprised of (1) a first layer comprising a high-density ester and and sunscreen, (2) a second aqueous layer, and (3) a third oily layer. The high-density ester layer usually has a specific gravity that is greater than that of the aqueous layer and the aqueous layer usually has a specific gravity that is greater than the oily layer. In preferred embodiments, each phase is substantially clear and has a volume approximately equal to that of the other phase(s). The phases disperse upon mixing and separate over time after mixing. The phases may be colored differently to enhance visual appeal. In some embodiments, emulsified boundary layer(s) form between the phases and constitute third or fourth phases.

Multiphase sunscreen compositions

The invention provides a hair conditioning formulation useful in repairing split ends comprising: (a) an amphoteric or cationic guar gum; and (b) a Necon fatty dialkyl amine salt, wherein the formulation contains natural or synthetic gums.
