The invention relates to a dyestuff of plant origin, obtained from a colored part of a plant species, the cell tissues of which contain iridisomes responsible for the coloration of said part. It relates most particularly to a blue dyestuff obtained from the arils of the seeds of the plant species Ravenala madagascariensis. It also relates to compositions, in particular cosmetic compositions, especially intended for making up the skin or superficial body growths, containing said dyestuff.

Provided is a treated platy substrate, a method of making it, and methods of using it. The substrate can be synthetic mica, optionally comprising metal-oxide layers. The treated platy substrate is useful in cosmetic compositions.

An inorganic, non-quarter wave, heterogeneous multilayer effect pigment includes a platy substrate comprising an absorbing optically active metal oxide layer thereon, having an optical thickness from about 20 nm to about 400 nm; a layer of low refractive index material on the absorbing optically active metal oxide layer and having an optical thickness from about 10 nm to about 500 nm; and an outermost optically active layer of a non-absorbing high refractive index material on the low refractive index material and having an optical thickness from about 50 nm to about 1000 nm. The multilayer effect pigment exhibits a blue reflectance ratio (BRR) of at least 3, according to the equation: BRR=(Blue Max)/(Green Min); where Blue Max is the maximum reflectance exhibited over wavelengths 380 nm to 450 nm; and Green Min is the minimum reflectance exhibited over wavelengths 450 nm to 600 nm.

A cosmetic or dermatological composition comprising: a) at least one merocyanine of formula (1) or (2) ##STR00001## b) at least one oily phase comprising at least one alkyl or alkylene carbonate is provided. Also provided is a non-therapeutic cosmetic process for caring for and/or making up a keratin material, comprising applying to the surface of the keratin material, of at least one of the above compositions. Also provided is a non-therapeutic cosmetic process for limiting the darkening of the skin and/or improving the colour and/or uniformity of the complexion, comprising applying to the surface of the keratin material, of at least one of the above compositions. In addition, provided is a non-therapeutic cosmetic process for preventing and/or treating the signs of ageing of a keratin material, comprising applying to the surface of the keratin material, of at least one of the above compositions.

A composition is provided. The composition is a water-in-oil emulsion comprising an aqueous phase and an oil phase. The aqueous phase comprises water, one or more humectants, one or more preservatives, one or more preservative boosters, one or more stabilizers and/or one or more pH adjusters. The oil phase comprises one or more solvents, one or more emulsifiers, one or more emollients and/or one or more aesthetic modifiers. Methods of preparing the composition and methods of improving the appearance of skin are also provided.

A crosslinked polyorganosiloxane is obtained from the free radical-initiated addition polymerization of polymerizable polyorganosiloxane containing at least two free radical polymerizable groups.
