Abstract: A lubricating oil composition comprises an alkylnaphthalene which has one or two alkyl groups each having from 8 to 30 carbon atoms, and at least one member selected from benzo(b)thiophene and derivatives thereof, and naphthalenethiol and derivatives thereof. The composition has good oxidative stability.

Abstract: A liquid detergent composition comprising:(a) 5 to 50% by weight of a surfactant;(b) 1 to 30% by weight of a zeolite; and(c) 0.1 to 5% by weight of (i) a copolymer containing copolymerized components having the formulae (I) and (II) and a weight average molecular weight of 100,000 or more; or (ii) a copolymer containing the copolymerized components having the formulae (III), (IV), and (V): ##STR1## wherein R.sup.1 represents hydrogen or methyl,R.sup.2 represents hydrogen or methyl,R.sup.3 represents an alkyl group having 1 to 6 carbon atoms,R.sup.4 represents hydrogen or methyl,R.sup.5 represents hydrogen or methyl,R.sup.6 represents hydrogen or methyl,R.sup.7 represents methyl or ethyl,R.sup.8 represents an alkyl or alkenyl having 3 to 24 carbon atoms,M and M' represents hydrogen or a counter ion, andm/n is 2/8 to 7/3 (mol ratio).p/q is 2/8 to 8/2 (mol ratio) and r/(p+q+r)=1/50 to 20/50 (mol ratio).

Abstract: The present invention provides a process for manufacturing a porous polymer containing many voids in its interior, which has a small apparent specific gravity and is superior in terms of water absorbing properties, permeability and elasticity. The process comprises (1) forming O/W emulsion by using a water soluble surfactant wherein an inner phase of the O/W emulsion is a hydrophobic phase and an outer phase thereof is a water phase containing at least one water-soluble polymerizable monomer; (2) adding said O/W emulsion to a hydrophobic dispersing medium containing an oil-soluble surfactant to form O/W/O emulsion; and (3) polymerizing the monomer.

Abstract: An oral composition contains as a surface-active agent 0.1 to 5% by weight of a fatty acid ester of a sugar alcohol selected from the group consisting of lactitol, maltitol, maltotriitol, maltotetraitol, maltopentaitol, maltohexaitol, maltoheptaitol and mixtures thereof. The ester has an acyl group with 8 to 20 carbon atoms such as lauroyl. The oral composition which may be applicable as toothpaste, toothpowder, mouthwashes and the like has a pleasant taste as well as a good foaming power.
