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

摘要:
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.
摘要:
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., methyl (most preferred), ethyl, propyl, hydroxyethyl, and the like, benzyl, or mixtures thereof; each m is 2 or 3; each n is from 1 to about 4, preferably 2; each Y is —O—(O)C—, —(R)N—(O)C—, —C(O)—N(R)—, or —C(O)—O—, preferably —O—(O)C—; the sum of carbons in each R1, plus one when Y is —O—(O)C— or —(R)N—O)C—, is C6-C22, preferably C12-22, more preferably C14-C20, but no more than one R1 or YR1 sum being less than about 12 and then the other R1 or YR1 sum is at least about 16, with each R1 being a long chain C5-C21 (or C6-C22), preferably C9-C19 (or C9-C20), most preferably C11-C17 (or C12-C18), straight, branched, unsaturated or polyunsatruated alkyl, the average Iodine Value of the parent fatty acid of the R1 being from about 20 to about 140. The chelating agent is preferably diaminetriaminepentaacetic acid. The compositions display excellant clarity with a percentage haze in the transmission mode of a Hunter Color analysis of less than 90%, preferably less than 50%.
摘要:
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.

摘要:
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. After an appropriate settling interval, a portion of the caustic phase is drawn from the reaction mixture as a waste/neutralization stream while the other portion of the caustic phase and a very small portion of the amine phase may be sent to a recycle tank for use in subsequent reaction steps. The majority of the amine phase is treated using ion exchange resins to remove excess cations from the amine and clean amine is returned to the amine system.
