Abstract: A multiple emulsion having a dispersing form of water-phase/oil-phase/water-phase and a process for preparation thereof, and a multiple emulsion type cosmetics utilizing said multiple emulsion as a fundamental form, said multiple emulsion consisting of a dispersed phase and a dispersion medium, of which the dispersed phase is a water-in-oil type emulsion formed by dispersing water phase into oil phase which consists of an oil component and a oil-soluble emulsifier having such a hydrophile-lipophile balance that the oil component forms a dispersion medium of the water-in-oil type emulsion, and of which the dispersion medium is an aqueous solution which contains an water-soluble emulsifier having such a hydrophile-lipophile balance that the oil component forms a dispersion medium of an oil-in-water type emulsion and having such concentration that the oil-soluble emulsifier does not dissolved therein.

Abstract: Novel compounds having the general formula: ##STR1## wherein R is selected from hydrogen and methyl, effectively inhibit the growth of cancerous cells. These compounds are useful as carcinostatic agents.

Abstract: A hair conditioner composition in the form of an oil-in-water type emulsion comprising a high molecular synthetic oil with molecular weight of 1,500, selected from the group consisting of poly-alkyl glycol mono-alkyl ethers, phosphonates and high fatty acid esters thereof and alkylene oxide polyol adducts; a cationic surface active agent, a nonionic surface active agent and water. This composition may also include a liquid ester oil as optional component.

Abstract: Novel compounds trans- and/or cis-spiro[5-isopropylbicyclo[3.1.0]hexane-2,2'-oxiranes], process for the production of the novel compounds comprising reacting 3-isopropyl-2-cyclopenten-1-one with sulfoxonium methylide to form the novel compounds, process for the production of novel compounds comprising reacting 5-isopropylbicyclo[3.1.0]hexan-2-one with sulfonium methylide or sulfoxonium methylide to form the novel compounds, and process for the production of novel compounds comprising the steps of reacting 3-isopropyl-2-cyclopenten-1-one with sulfoxonium methylide to form 5-isopropylbicyclo[3.1.0]hexan-2-one and then reacting the 5-isopropylbicyclo[3.1.0]hexan-2-one with sulfonium methylide or sulfoxonium methylide to form the novel compounds. Trans- and/or cis-sabinene hydrates can readily be prepared from the novel compounds trans- and/or cis-spiro[5-isopropylbicyclo[3.1.0]hexane-2,2'-oxiranes].

Abstract: In order to electrically apply fluoride by means of iontophoresis on a tooth an intermittent direct current is made to flow through the tooth. More particularly, the intermittent direct current has a waveform whose leading edge immediately rises to a peak and which decreases exponentially in time. As a result electrochemical polarization may be avoided and the ratio of the current conduction time to the repetition period may be increased so that the uptake efficiency of fluoride by the tooth may be considerably improved in a smooth manner without the need of impressing an excessive current on the tooth. Therefore adverse effects on nerve systems may be avoided, a patient under treatment feels no pain and no unpleasant stimulus, and the tooth's substance may be so improved as to be free from dental caries or decay.

Abstract: The resin compositions for peel-off coatings comprise a certain film-forming polymeric resin, an organopolysiloxane having a polyoxyalkylene group as the side chain, and a solvent. The coating compositions applied to the surfaces of various shaped articles provide protective films thereon, and the films thus formed are tough and can exhibit an excellent peelability even after the lapse of a long period of time or after heating. The coating resin compositions are prepared by a method comprising heating the mixture of the above-named individual components at an elevated temperature, not at room temperature.

Abstract: A process for preparing .beta.-bourbonene which comprises irradiating internally or externally an essential oil containing germacrene D, such as ylang-ylang oil, cananga oil, the essential oil of Solidago altissima L., the essential oil of Solidago gigantea Aiton var. leiophylla Fern., with the light of low pressure or high pressure mercury lamp to obtain .beta.-bourbonene.

Abstract: An oral composition effective in the prevention of tooth decay is prepared by combining dextranase and gelatin or peptone in a nontoxic vehicle.

Abstract: A process for producing cholestanyl phosphate or epicholestanyl phosphate or salts thereof in which the hydroxyl group at the three-position of cholestanol or epicholestanol is converted into the phosphoric ester by reaction with a phosphorylating agent in an inert solvent and hydrolyzing or hydrogenating this ester.
