Liquid fabric softener compositions comprising (a) water-insoluble cationic softeners, (b) water-soluble cationic antibacterial agents and (c) cationic rheology modifying polymers are described that are stable homogenous mixtures. A method for determining stability of the softener formulations or determining the amount of component (a), (b) or (c) involves calculating a stability index of the formulation according to the following equation: Stability formula index=[(wt % of the (a) component+3*(wt % of the (c) component)]/[wt % of the (b) component], wherein a desirable stability index value is 2.5 or greater than 2.5.

Provided are wrinkle reducing and deodorizing dryer sheets and methods of making and using the dryer sheets. In one form of the dryer sheet, the wrinkle reducing and deodorizing dryer sheet includes an absorbent wet substrate in sheet form with a polyvinyl alcohol sheet adhered to one surface of the substrate. In another form the PVA sheet is added separately from that of the absorbent wet substrate sheet. The PVA sheet is preferably in the form of an uncoated non-woven of a thickness of 8 mil or less. The wet impregnated sheet contains a solution of quaternary ammonium salts of different water solubility. The method for using, the wrinkle reducing and deodorizing dryer sheet is added to a rotary dryer with a load of wet or dried garments to reduce wrinkling in the garments during the drying process, reduce static cling and refresh the treated clothing.

A cleaning solution for the removal of asphaltene deposits includes a first dispersant comprising a quaternary ammonium compound and a second dispersant comprising a pyridinium compound.

A composition comprising (a) an esterquat that is a quaternized reaction product of an alkanol amine and a fatty acid, wherein from at least 90 wt % to up to 100 wt % of the esterquat is comprised of triesterquat and from 0 wt % to up to 10 wt % of the esterquat is comprised of at least one of monoesterquat and diesterquat, and (b) a cationic surfactant. Also, a method of producing such a composition and a method of softening a fabric, and increasing fragrance delivery, comprising treating the fabric with the composition.

Aqueous hard surface cleaner compositions useful for removing permanent ink are disclosed. The compositions comprise 75 to 99 wt. % of water; 0.1 to 5 wt. % of a monoterpene; 0.1 to 5 wt. % of a C10-C17 fatty acid derivative; and 0.1 to 5 wt. % of one or more surfactants. The fatty acid derivative is selected from N,N-dialkyl amides, N,N-dialkyl esteramines, and N,N-dialkyl amidoamines. Preferably, a base such as sodium carbonate or monoethanolamine is also included. The invention includes concentrates comprising the non-aqueous components recited above, as well as other applications for the cleaners and concentrates such as graffiti removers and permanent ink erasers. The combination of a monoterpene and certain fatty acid derivatives, especially fatty N,N-dialkyl amides, unexpectedly enables even dilute aqueous compositions to rapidly decolorize black permanent marker from hard, non-porous surfaces.
