A three part cleaning composition uses C.sub.6 -C.sub.20 alkyl substituted lactam as a cleaning agent, an anionic surfactant and water to solubilize and remove oil or grease from hard surfaces. The lactam is provided in a ratio, relative to surfactant of 5-0.1 to 5-3.0, more preferably 5-0.1 to 5-1.0. The composition is surprisingly effective in forming micro-emulsions with the oil or grease and maintaining the emulsions for ease in disposal. Using an aqueous solution including C.sub.6 -C.sub.20 alkyl substituted lactam provides a low volatility, non-flammable degreasing solution, which is highly effective and biodegradable.

Aqueous oil removal composition containing higher-alkyl pyrrolidone

A hardwood floor cleaner composition is provided which is non-tacky, and cleans and shines in one-step, is free of silicones, does not dull the wood surface. The composition comprises (a) about 0.1-5%, preferably 0.2-2%, of a C.sub.6 -C.sub.24 alkyl pyrrolidone, preferably N-octyl-pyrrolidone; (b) about 0.1-5%, preferably 0.2-1%, of an anionic or nonionic surfactant, preferably sodium dodecyl sulfate; (c) about 1-5%, preferably 2-4%, of a shine booster, preferably a vinylpyrrolidone copolymer, such as vinylpyrrolidone-dimethylaminoethyl methacrylate (Gafquat.RTM. 755-N - ISP); and (d) about 0.5-2%, preferably 0.8-1.5%, of a film-former, for example, an acrylic emulsion, preferably Esi-Cryl.RTM. 405 (Emulsion Systems Inc.), which is 2-methyl-2-propenoic acid, copolymer with ethyl-2-propenoate, methyl-2-methyl propenoate and 2-propenoic acid, and (e) about 85-95%, preferably 88-93%, of water, or an alcohol, or mixtures thereof, by weight of the composition. A concentrate and an aqueous microemulsion of the composition of the invention also is provided herein.

Hardwood floor cleaner composition

This invention is directed to an environmentally safe, water soluble stripping composition comprising between about 30 and about 98.5 wt. % N-methylpyrrolidone or a 10/90 to 90/10 mixture of N-methylpyrrolidone and gamma-butyrolactone and between about 0.1 and about 5 wt. % cyclomethicone. The invention also concerns the use of this composition in a process for stripping organic coatings such as paints, resins, varnishes and shellac from substrates.

Method of activating N-methyl-2-pyrrolidone (NMP) varnish and paint

This invention relates to a glycol based anti-icing fluid containing between about 0.05 and about 2 wt. % of 1.5 to 5% crosslinked maleic anhydride/methyl vinyl ether copolymer and between about 0.01 and about 2 wt. % base to provide a pH of from about 6.5 to about 10.

Non-flammable, pseudo-plastic deicing composition

This invention relates to a glycol based anti-icing fluid containing between about 0.05 and about 5.0 wt. % of 0.2 to 1.0% crosslinked poly(N-vinyl pyrrolidone).

Acidified NMP is stabilized against color formation by including a chelating agent in the composition.

Acicified NMP compositions stabilized with respect to color formation

A method is provided herein which is particularly effective for removing or stripping varnish and paint from surfaces such as wood or metal which comprises activating NMP and/or BLO with about 1-30% by weight of an activator compound which is ethyl 3-ethoxypropionate (EEP).

Method of activating .alpha.-butyrolactone (BLO) with ethyl

This invention is directed to an environmentally safe, water soluble stripping composition which contains a solution of water, a water soluble ester containing from 4 to 10 carbon atoms and an amount of hydrogen peroxide or compounds which generate hydrogen peroxide in situ; which peroxide concentration is not in excess of 30 wt. % of the water/ester composition. The invention also concerns the use of this biodegradable composition in a process for stripping organic coatings such as paints and resins from substrates.

Method of activating n-methyl-2-pyrrolidone (NMP) and/or

A resin cleaner composition is provided herein for use as a cleaning solvent to remove cured, partially cured and uncured polyester or vinyl ester resin containing a free radical polymerization initiator from resin fabrication tools. The composition is characterized by the presence therein of a free radical inhibitor which suppresses the rate of free radical polymerization. Thereby the resin can be loaded in increased amounts in the composition without an accompanying increase in polymerization of the resin.

Resin cleaner composition

Acidified N-methyl-2-pyrrolidone (NMP) is activated with 1-20% by weight of ethyl 3-ethoxypropionate (EEP) to provide an effective composition for removal of both uncured and cured paints from wood and metal surfaces.
