Patent number: 5500154Abstract: A detergent composition containing efficient enduring perfume composition is provided. Specifically, the detergent composition comprises: a perfume composition comprising at least about 70% of enduring perfume ingredients characterized by having boiling points, measured at the normal, standard pressure, of about 250.degree. C. or higher, and an octanol/water partitioning coefficent P of about 1,000 or higher, i.e., having a logP, or calculated logP, of about 3 or higher. The perfume is substantially free of halogenated fragrance materials and nitromusks. The composition also contains from about 0.01% to about 95% of a detergent surfactant system, preferably containing anionic and/or nonionic detergent surfactants. The compositions can be in the form of granules, liquids, pastes, bars, etc.Type: GrantFiled: October 20, 1994Date of Patent: March 19, 1996Assignee: The Procter & Gamble CompanyInventors: Dennis R.

Patent number: 5500138Abstract: The present invention relates to liquid and solid biodegradable fabric softener compositions combined with highly enduring substantive perfumes. These compositions are naturally, or synthetically, derived perfumes which are hydrophobic, defined by having a low rinse water solubility (ClogP is greater than or equal to 3.0). These perfumes also have low volatility, a boiling point of 250.degree. C., or greater. These compositions provide better perfume deposition on treated fabric, and consequently are not substantially lost during the rinse and drying cycle for less impact on the environment. Also, these perfumes improve the physical stability of the softener composition.Type: GrantFiled: October 20, 1994Date of Patent: March 19, 1996Assignee: The Procter & Gamble CompanyInventors: Dennis R. Bacon, Toan Trinh
