A cosmetic composition is provided herein, the composition comprising: an ester of pentaerythritol and a benzoic acid having the formula (I) wherein Rand Rindependently indicate a hydrogen atom or a linear or branched fatty acid residue having 1 to 24 carbon atoms or a benzoic acid residue, and a cosmetically acceptable carrier.

Cosmetic composition

A one-phase microemulsion composition, which can be easily prepared without the use of special equipment, has high safety, and stays stable for a long period in an ultrafine emulsion state when the composition is added to an aqueous formulation, is provided by appropriately adjusting the ratio of (A) a hydrophilic nonionic surfactant, (B) a lipophilic nonionic surfactant, (C) an oil component, (D) a water-miscible solvent that does not interdissolve with the oil component, and the critical micelle concentration (CMC) of the hydrophilic nonionic surfactant in the water-miscible solvent is higher than that of the hydrophilic nonionic surfactant in water, and (E) water.

A skin treatment composition of the present invention is an external composition for skin comprising an alkylene oxide derivative expressed by Formula (I):RO-[(AO)(EO)]&#x2014;R&#x2003;&#x2003;(I)wherein AO is an oxyalkylene group of Cor C; EO is an oxyethylene group; m and n are 1&#x2266;m&#x2266;70 and 1&#x2266;n&#x2266;70 respectively, wherein EO is 20&#x2dc;80% by weight with respect to a total of AO and EO; each of Rand Ris a hydrogen or a hydrocarbon group having C. The alkylene oxide derivative (I) has a moisturizing effect, a rough skin improving effect, a stickiness improving effect, and a transdermal absorption promoting effect. When a refreshing agent is used together therewith in the composition of the present invention, the refreshing effect lasts for a long time and it is excellent in feeling of use without skin stimulation.

An ultraviolet light absorbent comprising an ester mixture derived from esterification of pentaerythritol or trimethylolpropane and a saturated branched-chain fatty acid with a carbon number of 8-18 and ortho- or paramethoxycinnamic acid in a specific ratio. The ultraviolet light absorbent with prescribed ultraviolet light absorbing power has a moderate viscosity and can be handled and worked without inconvenience and/or difficulty.

Ultraviolet light absorbent

A composition for treating hair comprised of a thiol compound that is a superior hair reductant and hair cosmetic, especially in terms of waving effect, odor, hair damage, texture and safety and where the thiol compound has the formula HS--(CH2)n--NH--(CH2)-m-NH2 and the n and the m are integers from 1 to 4. The composition may include the salts of the compound. The composition is useful for a method of treating hair by applying the composition to the hair; leaving the composition on the hair for a sufficient period of time, depending on the desired effect; and then removing the composition. The invention, in particular, relates to hair reductants as well as primary agents for permanent waving, pretreatment agents for hair dyeing, cosmetics for heated hair curling, cosmetics for frizzy hair and cosmetics for human hair removing.

Composition for treating human hair and method of use

An aerosol composition containing a composite powder and one or more of propane, isobutane, n-butane and a liquefied petroleum gas (i.e., LPG) which is a mixture thereof, a chlorinated hydrocarbon and dimethyl ether.

Aerosol composition

A magnesium aluminometasilicate coated composite powder which comprises magnesium aluminometasilicate, or magnesium aluminometasilicate and at least one other powder coated on a surface of a core powder and which is usable in, for example, a skin treatment agent, decodorant, and oral composition.

Magnesium aluminometasilicate coated composite powder and use thereof

A composite powder wherein an organic or inorganic core powder is substantially completely covered with one or more types of organic, inorganic, or metallic powders having an average particle size one-fifth or less of the average particle size of the above core powder by means of mixing and compression. The composite powder may be manufactured by mixing and compressing the above core powder and coating powder using a ball mill or other mixer charged with a ball shaped mixing medium of an average diameter of 5 mm or less. This composite powder may be used in, for example, skin treatment agent, makeup type cosmetics, sunburn preventing cosmetics, deodorants.
