A method for producing polygonic Zn oxide platelets having a median specific surface area of more than 25 square meters per gram, in controlled size and morphology, the method comprising: preparing a medium including Zn or its compounds at a concentration within the range between 1.55 and 7.75 moles of Zn/L, in a medium suitable to substitute Zn ions by releasing free protons thereby forming a complex structure including Zn; agitation of the medium in a vessel at a temperature within the range between 50 and 320° for a duration up to 10 hours to obtain a suspension; filtering the suspension to obtain a filtrate including solid particles; drying and then calcination of the dried filtrate; wherein the agitation is performed with one or more radial flow impellers so that the Reynolds' number in the vessel is higher than 2500 and lower than 10000.

The present disclosure relates to a modified pearlescent powder and a method of preparing the same. The modified pearlescent powder includes a pearlescent powder, a lauroyl lysine powder located on a surface of the pearlescent powder, and a fluorine-containing silane coupling agent connected to the pearlescent powder by covalent bonds. The present disclosure also relates to a cosmetic including the modified pearlescent powder.

At least one embodiment, relates to a method for making cosmetic emulsions comprising the steps of preparing a uniform (suspension) dispersion of at least one water soluble polymer in a mixture containing at least one fatty alcohol. The mixture is to be sufficiently uniform to be processed by flaking, pastillating, prilling or otherwise solidifying the mixture which is then to be added to a cosmetic emulsion oil phase before combining with a water phase.

The invention relates to a nail varnish composition comprising: a) an embossed effect pigment comprising a metallic substrate in platelet form with embossed structure having a periodic pattern with diffractive elements, said substrate having been produced by PVD methods, and optionally at least one coating applied to the substrate, wherein the substrate has an elemental metal content of 80% to 100% by weight, based on the substrate, and wherein the effect pigment has been treated with a leafing additive for surface modification, b) at least one hydrocarbon resin as binder, c) at least one solvent or solvent mixture and d) optionally further auxiliaries. The invention further relates to a process for producing the nail varnish composition.

Provided is a white pigment for cosmetics capable of giving a cosmetic that gives a coating film having less stickiness and higher long-lasting properties. A white pigment for cosmetics of the present invention includes a titanium phosphate powder, the titanium phosphate powder includes crystal particles of titanium phosphate, and a ratio (oil absorption value/specific surface area) of an oil absorption value (ml/100 g) to a specific surface area (m.sup.2/g) of the crystal particles is 2.0 or more.
