Benefits of technology

The present invention provides compositions which exhibit improved cleaning of soils from and / or care of and / or treatment of fabric articles. These benefits may be delivered to the fabric article treated by the compositions of the present invention while maintaining excellent fabric care properties.

Problems solved by technology

Although washing machines and laundry detergents have become quite sophisticated, the conventional laundry process still exposes the fabric articles to a risk of dye transfer and shrinkage.
Significant portions of fabric articles used by consumers are not suitable for cleaning in a conventional laundry process.
Even fabric articles that are considered “washing machine safe” frequently come out of the laundry process badly wrinkled and require ironing.
By avoiding water these processes minimize the risk of shrinkage and wrinkling; however, cleaning of soils, particularly water-based and alcohol-based soils, is very limited with these processes.
These methods are complex, requiring a wide range of compositions to address the variety of stains encountered, very labor intensive and often result in some localized damage to the treated article.

example 1

Synthesis of Oleyl Based Sucrose Esters with an Average Degree of Esterification of 5.0:

Materials: oleyl (from soybean feedstock) sucrose ester=7.75 (MW=2390 g / mole) DMSO (Dimethylsulfoxide−EM Science)

Sucrose (342 g / mole−Domino Sugar)

Potassium Carbonate Catalyst

Procedure:

Add the DMSO and sucrose into a 12 Liter reactor and mix well to dissolve the sucrose. Then add the oleyl ester 7.75 and 30 g catalyst. Heat to 100-110° C. React until desired degree of esterification is reached by measuring on SFC (supercritical fluid chromatography). Nitrogen is swept over the reactor.

When reaction is completed, cool to ˜65° C. then wash with 10% water and gently mix. Centrifuge at ˜6000 rpm for 5 minutes to remove remaining catalyst, soap and DMSO. Decant off the top liquid layer. Evaporate any remaining DMSO / Water by running material through the 2″ Wipe Film Evaporator (WFE) at 100° C. and ˜0.8 mm Hg.

example 2

A control fabric care composition containing a nonionic surfactant and one or more cleaning adjuncts is prepared by mixing the components as following:

ComponentsConcentration (wt %)Surfactant - Tergitol ® 15S-3*50Propylene glycol25TSF-4446**10Water15Total100

*a secondary alcohol nonionic surfactant from Dow

**a silicone copolyol from General Electric

This detergent composition is diluted with D5 / 0.5% water to 1 wt % concentration in the resulting wash liquor (referred to as “Example 2”). The stain removal or fabric cleaning capability of Example 2 is tested according to ASTM D4265-98 using cotton swatches and artificial stains.

example 3

A detergent composition is prepared according to Example 2, except that a sucrose ester (compound 1) was added at 15% of the formula partially replacing propylene glycol. This composition is diluted with D5 / 0.5% water to 1 wt % concentration in the resulting wash liquor. The stain removal or fabric cleaning capability of the composition is tested according to ASTM D4265-98 using cotton swatches and artificial stains. Example 3 shows improved stain removal on grass, US clay and spaghetti sauce compared to Example 2.

Abstract

Compositions for treating fabric articles, especially articles of clothing, linens and drapery, wherein the compositions provide improved cleaning of soils from and / or care of and / or treatment of fabric articles, especially while providing superior garment care for articles sensitive to water as compared to conventional fabric article treating compositions, are provided.

Description

FIELD OF THE INVENTION The present invention relates to compositions for treating fabric articles, especially articles of clothing, linens and drapery, wherein the compositions provide improved cleaning of soils from and / or care of and / or treatment of fabric articles, especially while providing superior garment care for articles sensitive to water as compared to conventional fabric article treating compositions. BACKGROUND OF THE INVENTION For the cleaning of fabric articles consumers currently have the choice of conventional laundry cleaning or dry cleaning. Conventional laundry cleaning is carried out with relatively large amounts of water, typically in a washing machine at the consumer's home, or in a dedicated place such as a coin laundry. Although washing machines and laundry detergents have become quite sophisticated, the conventional laundry process still exposes the fabric articles to a risk of dye transfer and shrinkage. Significant portions of fabric articles used by co...
