Described herein is a powdered soap comprising a plurality of particles, each of the particles comprising a polyquat, a clay, and a fatty component.

One compound (100) according to the present invention contains silicon fine particles having a capability of generating hydrogen or aggregates of the silicon fine particles. The compound that contains the silicon fine particles or the aggregates having a capability of generating hydrogen is capable of generating hydrogen in the body of, for example, an animal that has ingested the compound. For a plant, the compound can be disposed or charged into, for example, moisture (water-containing liquid) or fertilizer to be provided to the plant, to supply the plant with hydrogen generated from the compound.

Disclosed are hair care and hair cleansing compositions as well as skin care and skin cleansing compositions comprising a fibrous material of natural origin and obtained from plants. The fibrous material comprises micro-scaled and/or nano-scaled fibril agglomerates. Such compositions show pleasant skin feel and comfort during and after application, as well as fast drying and fast absorption into skin. The compositions obtained are also particularly well suited for the topical delivery of cosmetic and pharmaceutical active substances into skin. Additionally, a method to obtain said hair care or hair cleansing composition or said skin care or skin cleansing composition is disclosed.

The invention relates to a powder for use in a powder jet device for cleaning teeth, wherein the powder comprises granules having an average particle size of 20 μm to 220 μm and the granules comprise primary particles and a binder, wherein the primary particles have an average particle size smaller than the average particle size of the granules. The invention also relates to a process for preparing the powder and the use of the powder for cleaning teeth.

Described herein is a powdered soap comprising a plurality of particles, each of the particles comprising: an ionic polymer; and a fatty component comprising compounds having C.sub.8 to C.sub.18 chains.

An oil-in-water type emulsion is characterized in that a fumed silica particle group in which lower order aggregates are aggregated with each other to form a higher order aggregate by a non-chemical bond forms a network-like surrounding structure including an oil inside the network-like surrounding structure.

Cosmetic and dermatological compositions, including color changing compositions, are provided which typically include a plurality of synthetic particles having a size in the micrometer or nanometer range. Each synthetic particle typically includes one or more aggregates of a pigment selected from phenoxazone, phenoxazine, and a derivate or precursor thereof, and a stabilizing material which has a refractive index larger than 1.45; the aggregates having a size larger than about 100 nm and the composition being biodegradable and biocompatible.

An oxidative stress inhibitor 100 of the present invention contains silicon particles capable of generating hydrogen. In a preferred aspect of the oxidative stress inhibitor 100, the following effects (a) and/or (b) can be exhibited. (a) The total amount of generation (total amount of production) is increased. (b) The amount of generation of hydrogen per unit time (i.e. rate of generation of hydrogen), particularly the rate of generation of hydrogen in the initial stage is increased.

A fibrous structure with a plurality of fibrous elements and agglomerated particles. The agglomerated particles can be matrix particles containing perfume.
