Patent Application
20060116304
The present invention relates to perfume compositions that are useful for masking odors, cleaning and/or treatment compositions comprising such compositions, and processes of making and using same.
Consumers prefer that articles, such as garments, be as clean as possible. Such consumers typically associate the odor of a cleaned or treated article with the degree of cleanliness of such article. Thus, the effectiveness of a cleaning and/or treatment composition, from a consumer's perspective, is typically directly linked with the odor that such composition imparts to an article that is cleaned or treated with such composition. Applicants recognized that certain materials, such as esterases and lipases, can generate objectionable fatty acid odors, particularly short-chain fatty acid odors such as the odor of butyric acid. However, such materials can be particularly effective cleaning agents. Unfortunately, consumers typically associate the odors resulting from the use of such agents with a lack of cleanliness. Thus, there remains a need for a perfume composition that masks fatty acid odors, cleaning and/or treatment compositions comprising such compositions, and processes of making and using same.
The present invention relates to perfume compositions that are useful for masking fatty acid odors, cleaning and/or treatment compositions comprising such compositions, and processes of making and using same.

Processes of Making Perfume Compositions
Perfume compositions of the present invention may be made by ad-mixing of perfume raw materials, which are typically liquids. Certain perfume raw materials are solid materials and can require gentle heat to homogenise with the rest of the perfume. The perfume blend can also comprise a significant proportion of a diluent (e.g dipropylene glycol), an antioxidant or a solubilising material. Solubilisers can be particularly advantageous where the surfactant level is low in order to disperse the perfume in a predominantly hydrophilic matrix such as aqueous liquid cleaners.

Processes of Making Cleaning and/or Treatment Compositions
The cleaning and/or treatment compositions of the present invention can be formulated into any suitable form and prepared by any process chosen by the formulator, non-limiting examples of which are described in Applicants' examples and in U.S. Pat. Nos. 5,879,584; 5,691,297; 5,574,005; 5,569,645; 5,565,422; 5,516,448; 5,489,392; 5,486,303.
Method of Use
The present invention includes a method for cleaning, treating and/or masking the odor of a situs for example, a surface or fabric. Such method includes the steps of optionally washing and or rinsing a situs, then contacting an embodiment of Applicants' perfume composition or consumer product containing such composition, in neat form or diluted in a wash liquor, with at least a portion of the situs then optionally rinsing such situs. The situs may be subjected to a washing step prior to the aforementioned rinsing step. For purposes of the present invention, washing includes but is not limited to, scrubbing, and mechanical agitation. As will be appreciated by one skilled in the art, aspects of the consumer products of the present invention are ideally suited for use in laundry applications. Accordingly, the present invention includes a method for laundering a fabric. The method comprises the steps of contacting a fabric to be laundered with a cleaning laundry solution comprising at least one embodiment of Applicants' cleaning and/or treatment composition, cleaning additive or mixture thereof. The fabric may comprise most any fabric capable of being laundered in normal consumer use conditions. The solution preferably has a pH of from about 8 to about 10.5. The consumer products may be employed at concentrations of from about 500 ppm to about 15,000 ppm in solution. The water temperatures typically range from about 5° C. to about 90° C. The water to fabric ratio is typically from about 1:1 to about 30:1.
Test Methods
1.) cLogP: The cLogP of a perfume component is determined in accordance with the protocol described in U.S. Pat. No. 6,916,769 and when a perfume composition is described and/or recites that at least 80% of said perfume component has a certain cLogP value, it means for example that 8 out of 10 or 4 out of 5 etc. of the recited perfume components have the recited cLogP.
In following detergent compositions, enzymes levels are given as percent pure enzyme per 100 grams total composition and the perfume component is a perfume according to the present invention and/or Examples 1 and 2 above. The perfumes used in Examples 3 through 6 are perfume compositions according to the present invention, for example the perfume compositions of Examples 1 and 2. Unless stated otherwise, the balance of the compositions of Examples 3 through 6 are water and minors such as, suds suppressors etc. Abbreviated component identifications for Examples 3 through 6 are as follows:
Each composition is combined with separate aliquots of solvent to result in separate solutions comprising from about 500 ppm to about 15,000 ppm of the respective composition. Articles, including garments or hard surfaces, are contacted with the respective solution. When the article is a garment, the solvent to fabric mass ratio is from about 1:1 to about 100:1 and the solution temperature is from about 5° C. to about 90° C. Then the article is optionally washed and/or rinsed. The resulting articles' odor, appearance and/or color is improved and/or maintained.
Perfume ester stability is assayed in the following manner. Blends of perfume esters disclosed in the present application are made by ad-mixing perfume ester raw materials that are disclosed in the present application in equal weight percents. The resultant perfume is added at a 0.3% level to a liquid detergent, sold under the trade name TIDE®. Ester degradation is monitored at time 0 and 24 hours after storage at 20-25° C., both in-product and in a wash solution made by adding 1.5 g of the above liquid detergent to 1 liter of water. The ester content of the resultant liquids and solutions is assayed via standard headspace gas chromatographic methods as described for example in Janusz Pawliszyn “Application of Solid Phase Microextraction”, RS.C, Chapter 26, pages 349-457, 1999. Specifically headspace solid phase microextraction (SPME) is followed by thermal desorption GC/MS analysis. The SPME fiber is coated with 100% polydiemthyl siloxane (PDMS). The thickness of the polymer film on the fiber is 100-um. Samples are put into 20-mL headspace vials with septum seal, and equilibrated for 60 minutes before analysis. For sampling the fiber is placed in the headspace of the sample vial and absoption is carried out for 20 minutes. Then the samples are injected to the GC column under 240° C. for 5 minutes in the injector. GC/MS system used for this work is a 5973 MS couple with 6890 GC, both from Agilent technologies. Separation of the PRM components is accomplished using a 60-m×250-um i.d. capillary column coated with 1-um PDMS phase. The perfume esters show a less than 80%, less than 50% and even less than 20% degradation profile.
