Abstract: Disclosed herein is a medicinal adhesive for percutaneous administration of a drug consisting of a support (backing layer), an adhesive layer comprising an oil-soluble drug, an adhesive resin, a penetration enhancer, a water-absorptive material and a lenitive agent, and a separate liner, charaterized in that the adhesive layer has a laminated structure having 2 to 5 layers and each layer has different water absorption capacities, and the drug is a oil-soluble, non-steroidal drug. For the adhesive of the present invention, the lowest layer which is to be contacted with the skin has the lowest water absorption capacity and the most upper layer in contact with the support has the highest water absorption capacity, or vice versa.

Abstract: Polyethoxylated vitamin E having the formula (I): ##STR1## wherein, R is --CH.sub.2 CH.sub.2).sub.n H,n is an integer from 2 to 100, inclusive,A is ##STR2## B is --CH.sub.3 at the 5-, 7- or 8-position, and m is 1, 2 or 3.can be prepared by reacting a vitamin E or an ester thereof with ethylene oxide, using a catalyst under pressure and anhydrous conditions, and shows anti-oxidation and oxidation stability similar to that of vitamin E acetate as well as excellent moisture retention and surfactant activity not shown by vitamin E and vitamin E acetate. Moreover, the compound is highly safe in the living body.

Abstract: The present invention provides quaternary ammonium-substituted saponin ethers having improved electrostatic and hydrophobic interactive activities, and therefore very useful in hair-care and skin-care products. The product of the invention, particularly, eliminates efficiently the static flyaway of hair and gives excellent conditioning effect to hair when used in hair-care products. The quaternary ammonium-substituted saponin ethers can be prepared by reacting a soya or ginseng saponin or an aglycone thereof with a cationic compound selected from quaternary ammonium halohydrin or quaternary ammonium epoxide.

Abstract: A casing for compact in which the main body of the casing consists of upper and lower bodies, said upper and lower bodies forming pivot retaining bores between them. The pin portions of a lid are pivotally supported in the pivot retaining bores. Thus, the lid is pivotally linked to the main body, thereby providing a strong casing for compact without disjoining of parts or deteriorating of appearance.

Abstract: The present invention relates to a novel quaternary ammonium-substituted sterol derivative of the following formula: ##STR1## wherein Q represents an anion of a strong inorganic acid, A represents an oxygen, R.sub.1, R.sub.2, R.sub.3, t, n, and the sterol Rst are defined as herein. The compounds of the present invention as a result of introducing a cationic group into hydroxy group of sterols of ethoxylated compounds thereof which are non-ionic, shows the enhanced substantivity against substrate having, on its surface, an anionic characters under normal conditions such as skin and hair of human being. The compound of the present invention can be used in the field of cosmetics.

Abstract: The present invention relates to a novel cationic polymer processing U.V. absorbing ability which is produced by the ester bonding of a cationic U.V. absorber to the terminal of the polymer. Unlike conventional nonionic U.V. absorbing polymers or nonionic or anionic U.V. absorbers, the U.V. absorber according to the present invention exhibits an improved substantivity to several anionic substrates, for example, hair, skin, and the like, due to the presence of a positively charged substituent group.
