Abstract: An emulsified composition comprises an oily substance and an emulsifying agent which emulsifies said oily substance in water, characterized in that at least one selected from glucose fatty acid monoesters and alkyl glucoside fatty acid monoesters having 1 to 4 carbon atoms in the alkyl group is used as the emulsifying agent.

Abstract: A process for separating an optically active substanbce comprising the steps of:(a) effecting a transesterification reaction between an ester of a linear or branched aliphatic racemic alcohol and an alcohol in an organic solvent containing an enzyme suspended therein; and(b) separating an optically active compound from the resultant reaction mixture.

Abstract: A racemic alcohol is subjected to the optical resolution by irreversibly esterifying one of the two antipodes of the racemic alcohol with an acid anhydride or enol ester of a carboxylic acid in a organic solvent in the presence of a hydrolase. This optical resolution uses a non-aqueous organic solvent in which the hydrolase is insoluble and involves an irreversible esterification, thus permitting an efficient optical resolution and improving recovery and re-usability of the hydrolase.

Abstract: A hair cosmetic composition comprising a polymer vesicle obtained from the polymerization of a surfactant monomer vesicle haing quaternary ammonium as a cation moiety and a polymerizable anion as a counter ion.

Abstract: Novel compounds used as polymerizable monomers in a dental adhesive composition, and having a general formula (1): ##STR1## wherein R.sup.2 is a carboxyl group and R.sup.3 is a hydrogen atom when R.sup.1 is a methyl group, and R.sup.2 is a hydroxyl group and R.sup.3 is a carboxyl group when R.sup.1 is a hydrogen atom, that is, N-methyl-N-(2-hydroxy-3-methacryloyloxypropyl)-m-aminobenzoic acid and 2-hydroxy-4-[(2-hydroxy-3-methacryloyloxypropyl)amino]benzoic acid are disclosed.

Abstract: A novel compound, 1-methacryloxyethane-1,1-diphosphonic acid and its salts provide improved adhesion to tooth substances when used as a polymerizable monomer in a dental adhesive composition.

Abstract: .alpha.-Thujene is prepared in high yields by isomerizing 1 mole of sabinene with 0.2 to 0.5 moles of an alkali metal, preferably lithium and 0.3 to 0.8 moles of a primary or secondary amine, preferably ethylenediamine. Formation of by-products such as p-cymene is minimized.

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].
