Treatment of skin tissue with photoactive materials and light, such as nanoparticles and formulations which are useful for cosmetic, diagnostic and therapeutic applications to mammals such as humans. In particular, embodiments of thermal treatment of the skin surface with metal nanoparticles in surfactant containing solutions are disclosed.

The present invention relates to a microcapsule particle composition that is composed of a sol-gel material. The microcapsule particle composition is well suited for personal care and cleaning products.

Cellulose particles include mother particles, containing cellulose as a principal component; and a coating layer that coats the mother particles, in which the average circularity of the cellulose particles is 0.97 or more, and the relation between carbon atom amount Cs and oxygen atom amount Os in the cellulose particles measured by X-ray photoelectron spectroscopy satisfies the formula A1: Cs/Os2.0.

An unground N.sup. long chain acyl lysine crystal production method that includes: preparing a solution having at least one type of N.sup.-long chain acyl lysine dissolved in an acidic or basic solvent including water and/or one type selected from water soluble organic solvents; dipping the solution into an acidic solution having a pH of at least 0.2 and less than 2.0, at a temperature of no more than 20 C.; and crystallizing N.sup.-long chain acyl lysine crystals.

A powder composition including composite particles, wherein the composite particles present an inorganic core, a hydrophobic coating composition and a hydrophilic coating composition, wherein the hydrophilic coating composition includes microcrystalline cellulose and from 20% to 60% of hydroxypropylmethylcellulose in weight relative to the total weight of the hydrophilic composition. The invention further relates to a process for obtaining such powder composition as well as cosmetic compositions including the powder composition.

Zinc oxide particles are prepared as a dry powder through a vapor phase formed by a plasma process, or by introducing defects into stoichiometric zinc oxide particles in a liquid carrier through mechanical stress. The zinc oxide has an O:Zn ratio of at least 0.99, an average particle size of 10 to 300 nm, and a sufficient concentration of oxygen vacancies and zinc vacancies to give a dispersion of the particles in C12-C15 alkyl benzoate an orange to tan color corresponding to a E value of at least 15 in a Dispersion Color Test. The particles contain no aggregates and have no detectable particles 500 nm or larger, on a number-weighted basis

Resin particles have closed cells inside and have a volume-average particle size of 1 m or more and 30 m or less, the closed cells have an average long axis length of 0.1 m or more and 2.0 m or less, and a closed cell porosity is 1% or more and 40% or less.

A non-woven fabric wipe having a layered fiber web structure. A first layer, a second layer, a fourth layer, and a fifth layer of the non-woven fabric wipe are all melt-blown fiber webs mainly composed of melt-blown fibers; a third layer of the non-woven fabric wipe is a wood pulp fiber web mainly composed of wood pulp fibers; the melt-blown fibers in the melt-blown fiber webs of the second layer and the fourth layer are partially interwoven in the adjacent wood pulp fiber web of the third layer, Because the non-woven fabric wipe of the present invention is composed of five layers of fiber webs, when the melt-blown fiber webs of the second layer and the fourth layer are consolidated, the portions interwoven with the wood pulp fibers are consolidated together with the interwoven wood pulp fibers, thereby forming a protective web that prevents the wood pulp fibers from moving.

The present invention relates to sunscreen compositions containing as UV filters solely a combination of i) bis-ethylhexyloxyphenol methoxyphenyl triazine (BEMT) and (ii) at least two pigmentary UV-filters, wherein the inorganic UV-filters are surface coated. Said compositions exhibit an appealing skin feel and look.

A single-dose oral hygiene unit of a toothpaste composition is blended together using a method of manufacturing disclosed herein. The oral hygiene units define an outer surface that is easily manipulated with a user's fingers. The ingredients are first blended together to create a final, blended toothpaste composition. A predetermined weight of blended toothpaste composition is extruded via nozzles into a plurality of cavities defined in a mold tray. The mold tray containing blended toothpaste composition is refrigerated for a predetermined time at a predetermined temperature until the blended toothpaste composition solidifies and the single-dose oral hygiene units are formed. The units may undergo a coating process whereby the outer surface of each unit is coated with an ingredient that prevents one or more units from sticking to one another or the container in which the units are placed and dispensed from.
