Benefits of technology

[0010] The process disclosed herein is effective in removing both non-polar stains, such as for example, oil and sebum, and polar stains, such as, for example, salts, components of coffee, tea and grape juice, from the article, for example, a garment, being cleaned and in suppressing redeposition of soil on the article.
[0028] It is believed that those cleaning compositions according to the present invention that lack a cyclic siloxane component would be more stable than those which include a cyclic siloxane component, in that cyclic siloxanes are known to ring open and polymerize under acidic and basic conditions.

Problems solved by technology

PERC suffers from toxicity and odor issues.
The petroleum-based products are not as effective as PERC in cleaning garments.

Embodiment Construction

1-162

[0039] The respective cleaning compositions used in Examples 1-162 were each prepared by combining the components listed below in the relative amounts set forth below in TABLES I-XIV below: methyl terminated tetradimethyl siloxane ("MD.sub.2M"); decamethylcyclopentasiloxane ("D.sub.5"); polyether siloxane compounds, each according to structural formula III above, were used:

[0040] A first set of textile samples (2".times.2" squares of red satin textile) were soiled with polar stains by pipetting droplets of an 8 wt % aqueous sodium chloride solution on each of the textile samples of the set. A second set of textile samples were soiled with nonpolar stains by pipetting droplets of fresh motor oil (Quaker State S...

Abstract

Methods for cleaning an article comprise contacting the article with a cleaning composition comprising a linear or branched volatile siloxane. In one embodiment, the method for cleaning the article comprises contacting the article with a cleaning composition comprising, based upon 100 pbw of the cleaning composition, 80 pbw to 99.99 pbw of a linear or branched volatile siloxane. In another embodiment, the method for cleaning the article comprises contacting the article with a cleaning composition comprising, based upon 100 pbw of the cleaning composition, 50.1 pbw to 99 pbw of a linear or branched volatile siloxane and a cyclic siloxane.

Description

Cross Reference to Related Applications[0001] This application claims the benefit of U.S. application Ser. No. 09 / 289,299 filed Apr. 9, 1999, which is hereby incorporated by reference.BACKGROUND OF INVENTION[0002] The present invention is directed to a composition, more specifically, to a siloxane fluid based composition, for use in dry cleaning and to a dry cleaning process using the composition.[0003] Current dry cleaning technology uses perchloroethylene ("PERC") or petroleum-based materials as the cleaning solvent. PERC suffers from toxicity and odor issues. The petroleum-based products are not as effective as PERC in cleaning garments.[0004] Linear volatile siloxanes and cyclic siloxanes have been reported as spot cleaning solutions, see U.S. Pat. No. 4,685,930. Other patents disclose the use of silicone soaps in petroleum solvents, see JP 09299687, and the use of silicone surfactants in super critical carbon dioxide solutions has been reported, see, for example, U.S. Pat. No. ...
