The invention is a column contact apparatus for contacting gas with liquid in an upflow in a column container, containing two or more stages of honeycomb structural bodies in the column container in a vertical direction, a space portion formed between the respective stages of the honeycomb structural bodies and a flow-aligning portion as back-flow prevention means provided in the space portion between the respective stages such that the flow-aligning portion is not brought into contact with the honeycomb structural bodies, the flow-aligning portion including a plurality of holes with hole diameters of 0.5 mm to 8 mm.

Column contact apparatus and method for operating the same

The present invention discloses the method for producing a tertiary amine, using the column reactor packed with catalyst layers, containing supplying a liquid and a gaseous raw materials from the bottom of the column, reacting these raw materials in the column, and discharging the product from the top of the column, wherein the column reactor includes two or more honeycomb catalyst layers as the catalyst layers, one or more spaces between each honeycomb catalyst layer, and one or more rectifying sections that prevents a partial or whole back flow of the raw materials, arranged in each space without contacting with the honeycomb catalyst layer.

Method for producing tertiary amine

Provided are a cosmetic composition which is an O/W/Oemulsion composition and contains, in the oil phases Oand Othereof, fine metal oxide particles having ultraviolet screening ability; and a preparation process of the cosmetic composition.

Cosmetic composition

A pearly luster composition containing a fatty acid glycol ester and water, and further containing any one selected from the group consisting of (1) a polyoxyalkylene nonionic surfactant and a fatty acid contained in an amount of from 0.3 to 3% by weight of the pearly luster composition, (2) a polyoxyalkylene nonionic surfactant and an aliphatic alcohol contained in an amount of from 0.3 to 3% by weight of the pearly luster composition, (3) a fatty acid monoglyceride contained in an amount of from 0.3 to 3% by weight of the pearly luster composition, and (4) an aliphatic ether contained in an amount of from 0.3 to 3% by weight of the pearly luster composition, as a crystallization additive. The pearly luster composition of the present invention is suitably used for shampoos, conditioners, body shampoos, liquid detergents, and the like.

Pearlescent composition

Provided is an O/W emulsion cosmetic composition, which contains the following components (A), (B) and (C):

O/W emulsion cosmetic composition

The present invention relates to a bleaching activator granule containing (a) a bleaching activator and (b) a specified alcohol which is liquid at room temperature (25&#xb0; C.).

Bleaching activator granule

To provide an anionic surfactant powder comprising a polyoxyalkylene ether sulfate which powder has high stability in hard water, high low-temperature solubility and is improved in powder characteristics such as caking characteristics, and a method of producing the anionic surfactant powder. An anionic surfactant powder comprising polyoxyalkylene alkyl ether sulfates in which the average addition mol number of alkylene oxides is 0.05 to 2, wherein the content of the polyoxyalkylene alkyl ether sulfates provided with alkylene oxides added thereto in an amount of 4 mol or more is 30 % by weight or less based on the total anionic surfactant, an anionic surfactant powder further comprising a water-soluble inorganic salt, a method of producing each of these anionic surfactant powders, and a detergent composition and a cement additive comprising these anionic surfactant powders.

Anionic surfactant powder

A process for producing an emulsion, including adding a mixture () comprising a water-soluble inorganic salt (a) and/or an aqueous solution containing (a) to a mixture () containing a surfactant (b), a surfactant-emulsifying agent (c) for emulsifying the surfactant (b), and a hydrophilic powder (d), and mixing mixtures () and () to emulsify the surfactant (b), wherein water-soluble inorganic salt (a) may be a carbonate, surfactant (b) may be an anionic surfactant and/or a nonionic surfactant, surfactant-emulsifying agent (c) may be a water-soluble polymer, and hydrophilic powder (d) may be an inorganic chelating agent.

Process for producing an emulsion

The invention provides a process for producing a granular anionic surfactant, including the steps of carrying out drying and granulation simultaneously while adding an anionic surfactant paste to a powder raw material under reduced pressure in a granulator provided with a stirring blade and a cracking blade to obtain granules.

Process for producing granular anionic surfactant

A process for preparing branched chain fatty acids or alkyl esters thereof comprising at least a step wherein unsaturated fatty acids having 10 to 25 carbon atoms, alkyl esters thereof or mixtures thereof are subjected to skeletal isomerization reaction in the presence of water or a lower alcohol at a temperature of 150.degree. to 350.degree. C. using a zeolite as a catalyst, the zeolite having a linear pore structure of pore size that is small enough to retard dimerization and large enough to allow diffusion of the branched chain fatty acids or alkyl esters thereof.
