    摘要: 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.

    摘要: 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, a surfactant, and an organic co-solvent. After the contacting step, the article is separated from the liquid dry cleaning composition. The method is preferably carried out at ambient temperature. The surfactant is preferably one that does not contain a CO2-philic group. The organic co-solvent is preferably an alkane and has a flash point above 140° F.

    摘要: 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, a surfactant, and an organic co-solvent. After the contacting step, the article is separated from the liquid dry cleaning composition. The method is preferably carried out at ambient temperature. The surfactant may be either one that contains a CO.sub.2 -philic group or one that does not contain a CO.sub.2 -philic group. The organic co-solvent is preferably an alkane that has a flash point above 140.degree. F.
