END FUNCTIONALIZED POLYSILOXANE SURFACTANTS IN CARBON DIOXIDE FORMULATIONS

A method for dry-cleaning articles such as fabrics and clothing in carbon dioxide comprises contacting an article to be cleaned with a liquid dry-cleaning composition for a time sufficient to clean the fabric. The liquid dry-cleaning composition comprises a mixture of carbon dioxide, water, and an e...

Zusammenfassung:	A method for dry-cleaning articles such as fabrics and clothing in carbon dioxide comprises contacting an article to be cleaned with a liquid dry-cleaning composition for a time sufficient to clean the fabric. The liquid dry-cleaning composition comprises a mixture of carbon dioxide, water, and an end-functional polysiloxane surfactant. After the contacting step, the article is separated from the liquid dry cleaning composition. The method is preferably carried out at ambient temperature. L'invention concerne un procédé de nettoyage à sec d'articles tels que des tissus et des vêtements dans du dioxyde de carbone. Le procédé comporte l'étape consistant à mettre en contact un article à nettoyer avec une composition liquide de nettoyage à sec pendant une durée suffisante pour nettoyer l'article. La composition liquide de nettoyage à sec comporte un mélange de dioxyde de carbone, d'eau et d'un tensioactif à base de polysiloxane à extrémité fonctionnelle. Après l'étape de mise en contact, l'article est séparé de la composition liquide de nettoyage à sec. Le procédé est de préférence mis en oeuvre à température ambiante.
