Abstract:
An aqueous rinse cycle fabric softening composition is provided containing an esterquat softening compound which remains physically stable and which is characterized by a stable viscosity below about 500 cps such that it remains easily pourable over a wide range of ambient temperatures and for extended periods of time.

Abstract:
Clear fabric softener microemulsion compositions have been developed for use in the rinse cycle comprising a combination of diester quaternary ammonium surfactants, diamido ammonium surfactants and selected organic solvants. Fatty co-softeners and oil perfumes may be included as optional ingredients. These microemulsions are converted to macroemulsions upon dilution with water in the rinse cycle to provide a fabric softening treatment.
Abstract:
Dispersible aqueous textile treatment compositions, such as fabric softeners, which include biodegradable quaternary ammonium fabric softener actives, and which exhibit excellent long-term storage stability, even where the storage is at elevated temperatures over long periods of time. The compositions comprise a biodegradable, fatty ester quaternary ammonium compound derived from the reaction of an alkanol amine and a fatty acid derivative, followed by quaternization; together with a periodate salt, such as potassium periodate.
Abstract:
A stable, aqueous, pourable and water dispersible fabric conditioning composition is provided which is biodegradable and capable of providing fabric softening concomitant with significant reduction and solubilization of unwanted mineral encrustations on fabrics to be conditioned. The conditioning composition comprises: (a) a mixture of: (i) a fabric softening effective amount of an inorganic acid salt of a finely divided fabric softening compound of formula (I) wherein R1 = C12 to C30 alkyl or alkenyl, R2 = R1CONH(CH2)m, R3 = (CH2CH2O)pH, CH3 or H, n = 1 to 5, m = 1 to 5, p = 1 to 10; and (ii) unreacted inorganic acid, wherein said inorganic acid salt is formed by the reaction of said fabric softening compound with an inorganic acid in a mole ratio of inorganic acid to fabric softening compound of from about 0.5:1 to about 5:1; (b) a C2-C6 carboxylic acid in an amount effective for removing encrustation from the fabrics to be conditioned; and (c) an aqueous solvent.
Abstract:
An environmentally compatible and biodegradable rinse cycle fabric conditioning composition is provided capable of providing improved softening with significant reduction and solubilization of unwanted mineral encrustations on fabrics to be softened. The composition comprises: (a) from about 1 to about 20 %, by weight, of a diesterified long chain fatty acid cationic fabric softener represented by general formula (I), wherein RCO represents the residue of a fatty acid having from about 12 to 24 carbon atoms; R2 and R3 represent independently a lower alkyl group or a hydroxyalkyl group having 1 to 4 carbon atoms; n and m are integers from 1 to 4 and X is a water-solubilizing anion; and (b) from about 1 to about 25 %, by weight, of unreacted organic or mineral acid.
