A softener composition comprises (a) 7 to 30 wt. % of a neutralization product with an inorganic or organic acid having not more than 6 carbon atoms of one selected from the group consisting of (a-1) an amine compound having 2 or 3 hydrocarbon groups each having 11 to 22 carbon atoms in its molecule and (a-2) an ion complex compound formed from 1 mole of a polyamide having a hydrocarbon group having 11 to 22 carbon atoms and 2 to 5 nitrogen atoms and 1 mole of an aliphatic acid having 12 to 22 carbon atoms and (b) 0.2 to 5 wt. % of one or more polyethers, each being an adduct of an alkylene oxide including ethylene oxide to a compound having 3 or more active hydrogens, which contains 50 wt. % or more of the polyoxyethylene units, having a molecular weight of 5,000 to 2,000,000. It is of the concentrated type and provides clothing with an improved softness and anti-static property.
The invention relates to fabric softeners with color-retaining action comprising: 3-25%, by weight, of component (A) consisting of Aa) 75-97%, by weight, of quaternary ammonium compounds of the general formula (I) ##STR1## and 3-25%, by weight, of at least one other compound Ab); (B) 0.5-6%, by weight, of customary auxiliaries and additives; and (C) ad 100%, by weight, of water.
This invention relates to fabric conditioning compositions containing inorganic acid salts of defined amidoamine compounds in combination with a carboxylic acid, which compositions are characterized by superior environmental compatibility relative to conventional quaternary ammonium fabric softening compositions concomitant with providing improved calcium salt solubilization and reduction of encrustation on treated fabrics.
The stability and softening performance of amidoamine fabric softeners, such as bis(hydrogenated tallow amidoethyl)-2-hydroxyethyl amine) is improved by protonating the amine with a neutralizing inorganic or organic acid and incorporating certain stabilizing emulsifiers, such as, N,N',N'-tris(2-hydroxyethyl)-N-tallow-1,3-diaminopropane, dimethylhydrogenated tallow amine, methyl dihydrogenated tallow amine, and oleic imidazoline). Mixtures of bis(hydrogenated tallow amidoethyl)-2-hydroxyethyl amine and bis(tallow amidoethyl)-2-hydroxyethyl amine also provide improved softening and form stable aqueous dispersions. The compositions may be highly concentrated for use at low levels or for further dilution prior to use.
Rinse-added fabric softening compositions are provided comprising mixtures of a substituted imidazoline fabric softener material and a highly ethoxylated hydrophobic material as a scum dispersant to prevent the formation of scum by interaction of the substituted imidazoline fabric softener material with anionic detergent surfactant and/or phosphate detergency builder entrapped in the fabric, and a liquid carrier. These, preferably biodegradable, compositions have good product stability, dispersibility, and concentratability, as well as excellent fabric softening characteristics.
A coating and tubing fluid for sutures, especially gut sutures, is provided. The coating composition includes linseed oil, an organic solvent and a catalyst. The tubing fluid includes water, a softening agent, a C.sub.2 -C.sub.4 alcohol and a lubricant of fatty acids, fatty acid alcohols and/or triglycerides of fatty acids. Gut sutures coated with the coating composition may be stored or packaged in the tubing fluid to provide sutures with improved flexibility, pliability, run-down performance and superior resistance to fraying and breaking.
