The present invention is directed to a lamellar oil-in-glycol gel comprising (a) at least one glycol, (b) at least one fatty alcohol, (c) at least one cationic surfactant and optionally (d) at least one benefit agent, said lamellar gel capable of providing enhanced mass and promoting the permeation of the benefit agent through a keratinous substrate such as the skin, hair and fingernails, providing both deep and superficial treatment thereof.

Lamellar oil-in-glycol gel compositions and the process of preparation

Polyelectrolyte complexes between anionic and cationic polymers are used to mend damaged hair fibers, especially damage exhibited by split ends. An improved test method designed for the assessment of the degree of split end repair is described which consists of tagging hair fibers and observing the repair process by stereomicroscopy.

Mending hair damage with polyelectrolyte complexes

A high skin friction cosmetic composition that can provide the consumer-desired sensory properties of traditional vanishing creams, stable at low pH, containing solid asymmetric particles and an anionic emulsifier having pKa values of less than about 4.5. The composition preferably further includes an acidic skin benefit agent. A method of controlling or preventing an oily skin appearance and/or feel especially in the facial area, by applying to the skin the inventive composition is also disclosed.

Low pH, high skin friction cosmetic creams

A cosmetic composition containing a retinoid and having an improved stability and mildness. Especially preferred compositions also include retinoid boosters and a polyhydric alcohol humectant.

Mild cosmetic composition with stabilized retinoids

Cosmetic compositions containing organic sunscreens along with a 4-substituted resorcinol derivatives of general formula I exhibit improved storage stability and oxidative stability:where each Rand R, independently, represents a hydrogen atom, &#x2014;CO&#x2014;R (acyl group), &#x2014;COO&#x2014;R CONHR; where R represents saturated or unsaturated, linear, branched or cyclic C-Chydrocarbon groups; andRrepresents (1) an alkyl group, having from 1 to 18 carbon atoms, preferably having from 2 to 12 carbon atoms, with or without substitution of one or more hydrogen atoms of a linear alkyl group with a methyl or ethyl group; e.g., Rconstitutes linear or branched chain alkyls, or (2) a group of the general formula formula (II)Where X is preferably H, n is 0 to 3 and the dashed lines represents an optional double bond.

Stabilization of sunscreens in cosmetic compositions

Cosmetic compositions containing a micronized metal oxide along with a 4-substituted resorcinol derivatives of the general formula I exhibit improved storage stability:

Stabilization of resorcinol derivatives in cosmetic compositions

Cosmetic compositions containing ferulic acid at a pH of from 3 to 5, in an aqueous phase, along with a polyol, have improved storage stability and dissolution at body temperature.

Stabilization of ferulic acid in cosmetic compositions

A cosmetic composition is provided which includes at least about 2% solid asymmetric particles, a retinoid solubilized in a fluid oil and wherein the fluid oil to solid particles are present in a weight ratio such that the composition exhibits a normal force value of less than &minus;100 milli-Newton containing a retinoid. The composition diminishes the appearance and feel of oily skin and is capable of delivering benefits associated with retinoids.
