Title (EN) PRE-TREATMENT METHODS AND COMPOSITIONS FOR CARBON DIOXIDE DRY CLEANING
(FR) PROCEDES ET COMPOSITIONS DE PRETRAITEMENT POUR LE NETTOYAGE A SEC AU DIOXYDE DE CARBONE
Abstract:
(EN) A method for dry-cleaning articles such as fabrics and clothing in carbon dioxide. The article includes a stained portion or region, which is pretreated with a pretreatment composition prior to initiating the cleaning cycle. The pretreatment step is followed by contacting the pretreated article to be cleaned with a liquid dry cleaning composition for a time sufficient to clean the article. The liquid dry-cleaning composition comprises a mixture of carbon dioxide, a surfactant, and an organic co-solvent. After the contacting step, the article is separated from the liquid dry cleaning composition. The pretreatment composition, in a preferred embodiment, comprises at least one of (a) a surfactant; (b) d-limonene, and (c) a C12-C15 alkane co-solvent. Preferably the pretreatment composition comprises at least two, and in some particularly preferred embodiments, the pretreatment composition comprises all three, of the aforesaid ingredients.
(FR) La présente invention concerne un procédé de nettoyage à sec d'articles tels que les textiles et les vêtements dans du dioxyde de carbone. L'article comporte une partie tâchée laquelle est prétraitée avec une composition de prétraitement avant de déclencher le cycle de lavage. Le prétraitement est suivi par la mise en contact de l'article prétraité avec une composition de nettoyage à sec liquide pendant un temps suffisamment long pour nettoyer l'article. La composition de nettoyage à sec liquide contient un mélange de dioxyde de carbone, un tensioactif, et un co-solvant organique. Après la mise en contact, l'article est séparé de la composition de nettoyage à sec liquide. Dans un mode de réalisation préférée, la composition de prétraitement contient au moins: (a) un tensioactif; (b) d-limonène, et (c) un co-solvant C12-C15 alcane. De préférence, la composition de prétraitement comprend au moins deux des ingrédients précités, et dans certains modes de réalisation préférées, la composition de prétraitement contient les trois ingrédients à la fois.
