A topically applied circulation enhancing agent suited for application over the entire body which has good transdermal absorptivity and causes little irritation is provided. A topically applied circulation enhancing agent is provided which contains a fatty acid ester denoted by general formula (1): 

Topically applied circulation enhancing agent and skin and hair cosmetic and bath agent containing the same

Provision of an N-acyl basic amino acid dispersion superior in dispersibility. The present invention provides a production method of an N-acyl basic amino acid dispersion having a pH of 2 to 12, comprising

N-acyl basic amino acid dispersion

Cosmetic powders which contain an N-mono long chain acyl basic amino acid and a particular &#x3b1;-aminolactam derivative are superior in spreadability on the skin and affinity to the skin upon application, and the lightness and moisture of the skin after application, as well as safety.

Cosmetic powder

The present invention provides a thickening composition simultaneously exhibiting suitable thickening performance and superior usability, which contains N-long-chain acyl acidic amino acid and/or a salt thereof, an amphipathic substance, an inorganic salt, and water as essential components, and has a viscosity of not less than 200 mPa&#xb7;s. By the addition of the thickening composition, moreover, cleansing compositions and cosmetic compositions for skin, hair and the like, which maintain thickening performance and usability, while containing N-long-chain acyl acidic amino acid and/or a salt thereof are provided.

Thickening composition

Herein is disclosed a pigment-dispersed resin composition comprising (a) a surface modified pigment in respect of which a surface modifying mixture consisting of a titanium oligomer and an organic acid ester is coated uniformly on the surface of the pigment particles and (b) a resin, usable, e.g., as an ingredient of a paint or a printing ink.

Pigment-dispersed resin composition

Herein are disclosed a resin magnet excellent in flow characteristics and magnetic properties comprising a surface modified magnetic powder in respect of which the surface of the magnetic powder particles has been coated uniformly with a surface modifying mixture consisting of a titanium oligomer and an organic acid ester, and a resin; a magnetic toner excellent in printing quality and resolution comprising a fine powder prepared by mixing and pulverizing a resin and such a surface-modified magnetic powder, and a fluidizing agent; a magnetic coating material comprising such a surface-modified magnetic powder, an organic binder, and a solvent; and a magnetic recording material excellent in magnetic and surface properties obtained by coating a substrate resin with a magnetic coating material comprising such a surface-modified magnetic powder, an organic binder, and a solvent.

Magnetic materials

A surface modifying agent for surface treating a filler in water which comprises 100 parts by weight of a zirconate base or/and aluminate base coupling agent(s) whose unhydrolyzable side chains have a solubility parameter (x) of 6.5-12, and 3 to 30 parts by weight of a nonionic surface active agent blended therewith having an HLB value (y) of 2-30 and containing no protonic hydrogen(s) in its molecule, wherein x and y satisfy a relationship of 4x-24.ltoreq.y.ltoreq.4x-18, as well as another surface modifying agent for the same purpose which comprises a mixture of 100 parts by weight of the above one or two coupling agents having a viscosity of 200 cps or more with 30-3000 parts by weight of a water-insoluble solvent, where the total mol fraction value (z) of the solubility parameters of the unhydrolyzable side chains of the coupling agent(s) and the solvent is 6.5-12, and 3 to 1000 parts by weight of the above nonionic surface active agent blended therewith, wherein z and y satisfy a relationship of 4z-24.ltoreq.y.ltoreq.4z-18. The inventive surface modifying agents have an excellent preservation stability and can perform water repellent treatment of fillers such as calcium carbonate in water.

Agent for filler surface treatment in water

The novel fluorinated carbon chain-containing aluminum compounds which are capable of imparting an SP value of desired level to inorganic materials and hence can be used as surface modifiers for improving the affinity between inorganic materials and fluororesins, fluorine-containing paints are disclosed.

Fluorinated carbon chain-containing aluminum surface modifier

An inorganic composition of improved characteristics comprising at least one particulate inorganic substance whose surface is modified by an N-acylated basic amino acid.

Surface modifier for inorganic substances

A detergent composition containing at least one ampholytic surface active agent of N.sup..epsilon. -long-chain-acyl-N.sup..epsilon.,N.sup..epsilon. -dimethyllysine or N.sup..epsilon. -long-chain-acyl-N.sup..alpha.,N.sup..alpha.,N.sup..alpha. -trimethyllysine or salt thereof represented by formula (I) or (II) below, and an anionic surface active agent. This detergent composition is superior in solubility, detergency, and sudsing on account of the synergistic effect of the two types of different components. This detergent composition exhibits high detergency in both soft water and hard water, and is mild to the skin and hair. ##STR1## (where RCO denotes an aliphatic acyl group of carbon number 8 to 22.).
