The present invention relates to a solid cosmetic composition and a manufacturing method therefor, wherein the solid cosmetic composition comprises a high content of an active ingredient without the use of a preservative or a surfactant and can improve the processability of products. In addition, the convenience of use and portability of the solid cosmetic composition can be improved since the active ingredient can be selectively or simultaneously loaded irrespective of hydrophilicity and hydrophobicity thereof and can be dissolved or released in water without a surfactant.

A process for producing porous particles of a polyhydroxyalkanoate (PHA) includes the following steps: providing a spray drying atomization chamber heated to an operating temperature comprised between 50° C. and 300° C.; providing an aqueous suspension having the PHA and an expanding agent which decomposes at the operating temperature of the atomization chamber, with the formation of at least one gaseous compound; and injecting the aqueous suspension into the atomization chamber provided at the operating temperature, so as to cause instantaneous evaporation of the aqueous suspension and decomposition of the expanding agent, with formation of the porous PHA particles. The particles obtained from said process can be used to obtain cosmetic compositions that are soft to the touch, with high oil absorbing capacities and high flow index, able to generate a uniform, filling effect for wrinkles and skin furrows, making the skin more glossy and compact.

Oral care compositions including peroxide, alumina, and optionally water. Dentifrice compositions including peroxide, alumina, and optionally water. Dentifrice compositions including peroxide, calcined alumina, and optionally water. Dentifrice compositions including peroxide, calcined alumina, uncalcined alumina, and optionally water. Methods of use to whiten teeth using one or more of the disclosed compositions.

An objective of the present invention is to provide an external preparation for concealing roughness that is easy to spread when applied, while also having effects of concealing roughness such as fine wrinkles. The external preparation for concealing roughness of the present invention comprises (a) 1% to 15% by mass of a wax; and (b) 4% to 25% by mass of a non-spherical powder; and has a viscosity of 50,000 to 150,000 mPa.Math.s.

The present invention relates to a process for preparing a crystalline merocyanine compound, comprising the step of dissolving a merocyanine compound in an organic, polar solvent, wherein the process is performed at a pH below than 7 in the presence of an acid, wherein residual levels of colored impurities are eliminated.

The present invention relates to a composition comprising: (a) at least one pigment; (b) at least one first copolymer of at least two monomers selected from (meth)acrylic acid, esters thereof, and salts thereof; (c) at least one second copolymer of styrene or α-methylstyrene and of at least one monomer selected from (meth)acrylic acid, esters thereof, and salts thereof, wherein the weight ratio of the amount of the (c) second copolymer(s)/the amount of the (a) pigment(s) is 1.0 or more, preferably 1.5 or more, and more preferably 2.0 or more, and the composition comprises at least one non-ionic surfactant in an amount of 0.5% by weight or less, preferably 0.3% by weight or less, and more preferably 0.1% by weight or less, relative to the total weight of the composition, or the composition comprises no non-ionic surfactant. The composition according to the present invention is suitable for a keratin substance such as the skin and the surface of a mucous membrane, and can provide the keratin substance with enhanced or improved cosmetic effects, such as better concealing effects of the original color of the keratin substance, as well as long-lasting makeup effects.

The present invention relates to a droplet-releasing cosmetics material, in particular cosmetics material comprising a polyhedral complex containing: in cosmetics which release a droplet by rubbing, a) a polyhedral structure wherein an interior is composed with a plurality of plate-like materials and has a space therein; and b) droplets contained in a space inside the polyhedral structure.

A cosmetics material according to the present invention releases a droplet by rubbing in use thereby having a visual effect and excellent feeling in sue and is silicone polymer-free type capable of solving the problem of side effects by the silicone polymer and the user's discomfort and has benefit of excellent stability in the cosmetic material of the polyhedral complex.

The core active components of the present composition, termed as de-ironizing inducers (DII), has a reducing agent and a precipitating agent. Molar ratios of the reducing agent with the precipitating agent range from 1:3-6 and the core components in the skincare product range from 0.1% to 10% w/w. The pH value of the skincare product is between 6.6 and 7.4. The skin care products can safely and effectively 5 remove iron in the skin, which has been shown to accelerate the visible signs of aging. The core components can also be used in combination with conventional skincare product compounds to achieve better anti-aging effects.

The present invention relates to a composition for skin external application. Specifically, a composition for skin external application comprising a stably formed lamella liquid crystal phase can be provided according to the present invention. In addition, according to the present invention, the composition can provide excellent skin moisturizing and skin barrier strengthening effects upon application on the skin, as well as act effectively as an agent for a cannabinoid type 1 receptor, such that it is expected that the present invention can provide a very effective effect for treatment or improvement of skin diseases and mental disorders associated with skin diseases.

A solid powder cosmetic is a solid powder cosmetic containing a powder component and an oily component, the contents of the powder component and the oily component are 70% to 95% by mass and 5% to 30% by mass, respectively, based on the total amount of the solid powder cosmetic, and the oily component contains (A) a hardened castor oil fatty acid ester and (B) a heavy liquid isoparaffin.
