Water-based, hair care products containing homogeneous terpolymers having both hair styling and conditioning properties

A low VOC (volatile organic compounds) hair spray composition having a combination of desirable user performance characteristics is described herein. The hair fixative resin in the composition is a terpolymer of 40-75% by weight of a vinyl lactam, preferably vinyl pyrrolidone, 15-40% of a polymerizable carboxylic acid, preferably acrylic acid or methacrylic acid, and 5-25% of a hydrophobic monomer, preferably a long chain alkyl (C.sub.8 -C.sub.24) acrylate, methacrylate, acrylamide or methacrylamide. The terpolymer has a K-value of 30-55, preferably 40-50, which provides compositions having good sprayability in both pump and aerosol form, and small, fine spray particles.

A homogeneous polymerization process is described for making substantially homogeneous terpolymers of, by weight, 55-99%, preferably 65-95% of vinyl pyrrolidone; 0.5-49%, preferably 1-25% of a quaternary amino monomer, preferably 3-methacrylamidopropyl trimethylammonium chloride; and 0.5-49%, preferably 1-25%, of a hydrophobic monomer, preferably octadecyl methacrylate. The homogeneous terpolymer provides dual hair styling and conditioning functions in hair care applications.

Charge imbalanced polyelectrolyte composition

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 water based wetting agent uses higher alkyl substituted lactam, anionic surfactant and water to enhance the wetting properties of herbicide and pesticide formulations. The composition is effective in enhancing wetting times, and in some instances increases the formulation effectiveness through enhanced contact, better penetration and lower surface tension. Utilizing a herbicide or pesticide formulation including the wetting agent provides a fast absorption of actives with rapid uptake to promote weed control with no or minimal phytotoxicity at the use levels.

Water soluble wetting agent for pesticide formulations

This invention relates to hydrolysis resistant, water-soluble ammonium salt solids which are biologically active and which are described by the formula ##STR1## wherein m has a value of from 1 to 3; n has a value of from 1 to 4 and is equal to the free valences in anion R; p has a value of from 1 to 3; R.sub.1, R.sub.2 and R.sub.3 are each independently selected from the group of hydrogen, and C.sub.1 to C.sub.2 alkyl; R.sub.5 and R.sub.6 are each independently selected from the group of hydrogen, hydroxyalkyl and alkoxyalkyl radicals having from 1 to 10 carbon atoms and R is the anion of a biologically active, water-insoluble anion having at least 1 deprotonized hydrogen and is derived from a biologically active, acidic, organic compound selected from the group of a carboxylic, thiocarbonic, sulfonic, sulfinic, thiosulfonic, thioacid, mono- and di-thiophosphate and phosphorous containing acid, having a pKa* value less than 5.

Crosslinkable copolymers of (a) 80-99% by wt. vinylpyrrolidone (VP) and 1-20% by wt. of a tertiary-amine-containing polymerizable monomer, e.g. vinylimidazole (VI) or 4-vinylpyridine (VPy), and (b) 80-99% by wt. VP and 1-20% by wt. of an epoxide-containing polymerizable monomer, e.g. allyl glycidyl ether (AGE) or glycidyl acrylate (GA), are reacted in solution, e.g. water, alcohol, or mixtures thereof, at a predetermined temperature, e.g. 50.degree.-70.degree. C., in a wt. ratio (solids basis) of (a):(b) of about 2:1 to 1:2, preferably about 1:1, in a solution concentration of about 10-30% of each, to provide a crosslinked PVP product, in gel form, suitable for use as an electrolead on a conductive foilbacking, or for bandages and wound dressings, and as a controlled release media for pharmaceuticals.
