wherein X is a halogen; wherein each R.sup.1 is independently selected from a substituted or unsubstituted C.sub.1-6 alkyl group; wherein each R.sup.2 is independently selected from the group consisting of a C.sub.1-6 alkanediyl group; wherein Y is a divalent bridging group; and wherein the deposition aid polymer enhances deposition of the dermatologically acceptable silicone from the hair cleanser onto mammalian hair.

One aspect of the present disclosure is an organic/inorganic composite powder and a composition including the same in which a coating film on a surface of an inorganic powder is not easily fall off under various conditions such as pH, temperature, physical force, etc., so that has excellent moisture retention and less transferring and allows for natural makeup.

A method and a kit-of-parts are provided for dyeing keratinous material. The method includes applying a first agent to the keratinous material and applying an second agent to the keratinous material. The first agent includes at least one organic silicon compound. The second agent comprises at least one colorant compound and at least one film-forming polymer. The colorant compound includes at least one effect pigment including a substrate platelet including synthetic mica. The colorant compound further includes a coating including at least a first metal oxide (hydrate) layer.

A process for dyeing or coloring keratin material, in particular human hair, using a C.sub.1-C.sub.6 organic alkoxysilane and an acidifying agent, is disclosed. The process comprises applying on the keratinous material a first composition (A), and a second composition (B). The first composition (A) comprises (A1) one or more organic C.sub.1-C.sub.6 alkoxysilanes and/or condensation products thereof, and (A2) at least one colorant compound selected from the group of pigments and direct dyes. The second composition (B) comprises (B1) at least one acidifying agent. A kit-of-parts for use in carrying out the process is also disclosed.

An external dermal composition and a method for beautifying skin are provided. The external dermal composition mainly includes a double nitrosyl-iron complex and a pharmaceutically acceptable additive. The external dermal composition delivers nitric oxide to a user's skin to beautify the skin when applied to the user's skin.

A composite powder according to an embodiment of the present disclosure has excellent UV blocking effect. The composite powder includes an ultraviolet ray-blocking coating layer containing ZnO on the surface of the plate-shaped substrate containing TiO.sub.2, thereby enabling the blocking of ultraviolet rays in the UVA and UVB regions, and is also expected to block fine dust through treatment with a silane compound or a silica compound.

Provided herein is a method of reducing or preventing sunburn caused from visible and ultraviolet radiation in a subject, the method comprising topically applying to the subject a sunscreen composition comprising inorganic UV filtering agents, antioxidants, and at least one inorganic pigment, wherein the at least one inorganic pigments and antioxidants are present in an amount effective to reduce or prevent sunburn caused from visible light. Also provided herein are sunscreen compositions and methods of increasing the SPF of a sunscreen composition that comprises at least one inorganic UV filtering agent.

The present invention relates to an anhydrous composition comprising at least one amino silicone, at least one alkoxysilane of formula (VIII), and at least one coloring agent chosen from pigments, direct dyes and mixtures thereof. The present invention also relates to a process for treating keratin fibers such as the hair.

The invention relates to a cosmetic product in the form of a creamy compact powder containing a) 30-65% by weight, on the basis of the total weight of the product, of a powder phase; b) 35-70% by weight, on the basis of the total weight of the product, of a liquid binder phase consisting of one or more liquid binders. The products according to the invention have hybrid properties between compact powdered products and poured products.
