Abstract: There is provided a regeneration process for converting oxazolidones such as hydroxypropyloxazolidone (HPOZD) to alkanolamines such as di-isopropanolamine (DIPA) and CO2. An amine stream containing HPOZD joins a stream that includes a caustic solution. The combined stream is passed to a tank where the caustic reacts with HPOZD to convert it to DIPA and CO2. The conversion of HPOZD to DIPA and CO2 requires a ratio of at least 2 moles of hydroxide for each mole of HPOZD in the solution. The conversion reaction is carried out in a reaction vessel at a temperature above 60° C. The reaction mixture is held in a feed tank for approximately 2 hours while being constantly mixed. After the reaction is completed, the mixture is allowed to settle which results in the virtually complete separation of the amine phase (containing DIPA, and water) from the caustic phase.

Abstract: Clear or translucent fabric softening compositions having a biodegradable fabric softening active and an added chelating agent are disclosed. The biodegradable fabric softening active preferably has the formula: [(R)4-m—N(+)—[(CH2)n—Y—R1]m]X(?)??(1) wherein each R substituent is hydrogen or a short chain C1-C6, preferably C1-C3 alkyl or hydroxyalkyl group, e.g.

Abstract: Rinse added fabric softening compositions containing pro-fragrant acetals or ketals which hydrolyze upon exposure of surfaces rinsed in solution of said compositions to a reduction in pH, thereby releasing a fragrance which is characteristic of one or more of the hydrolysis products.

Abstract: The present invention relates to perfume and fragrance pro-accords which are suitable for use in personal care and personal hygiene compositions as fragrance delivery systems. The pro-accords of the present invention slowly release fragrance raw materials upon contact with human skin thereby providing a prolonged fragrance benefit. The pro-accords serve as a means for delivering any fragrance raw material as well as other adjunct materials inter alia astringents, carriers, and diluents.

Abstract: The present invention relates to perfume or fine fragrance compositions inter alia perfumes, colognes, eau de toilettes, and after shave lotions, comprising pro-accord compounds which release their fragrance raw material components on a delayed basis therefore providing sustained fragrance levels to the user. Typically the pro-accords are comprised of orthoesters, ketals, acetals, orthocarbonates which release two or more fragrance raw materials upon hydrolysis. The present invention also relates to an article of manufacture comprising a first pro-accord containing reservoir and a second fragrance raw material reservoir and a means for admixing and applying the perfume material.

Abstract: Laundry and cleaning compositions comprising a nonionic or anionic ester of an allylic alcohol perfume having the formula: ##STR1## especially geranyl and neryl esters.

Abstract: Fabric softening compositions comprising fabric softening active(s), cellulase and an antioxidant effective amount of free radical scavenging antioxidant material and/or chelant.

Abstract: Esters of perfume alcohols having at least one free carboxylate group are provided. The esters have the general formula: ##STR1## wherein R is selected from the group consisting of substituted or unsubstituted C.sub.1 -C.sub.30 straight, branched or cyclic alkyl, alkenyl, alkynyl, alkylaryl or aryl group; R' is a perfume alcohol with a boiling point at 760 mm Hg of less than about 300.degree. C.; and m and n are independently an integer of 1 or greater. The esters are employed as perfume components in laundry and cleaning compositions such as fabric softening compositions.
