Abstract: Textiles are cleaned by first treating soiled areas of the textile with at least one pre-spotter material which is an alcohol polyoxyalkylene derivative or a benzoate ester. The textiles are subsequently dry cleaned in a medium based on liquid C02, typically also including a cleaning additive, particularly a multi-ester. The textile may also be treated with a fabric conditioner, particularly a fatty alcohol or fatty acid branched polyalkoxylate which may be included in the dry cleaning medium or in a subsequent rinse cycle.

Abstract: Detergent or micelle free cleaning media based on detergent free and/or micelle free liquid CO2 and including from 0.01 to 5% by weight of the formulation of a cleaning additive which is at least one multi-ester having a molecular weight of not more than 750 can be used in dry cleaning of textiles. Desirable cleaning additives are of the formula (1): R1(XR2)n where X, R1, R2, and n have defined meanings, particularly to be esters of multi-carboxylic acids and mono-hydroxy alcohols or esters of mono-carboxylic acids and multi-hydroxy alcohols.

Abstract: Fatty branched polyalkoxylates, particularly of the formula: R1O(AO)mR2 (I) where R1 is C8 to C30 aliphatic hydrocarbyl or acyl; AO is predominantly branched alkyleneoxy, particularly propyleneoxy; m is from 2 to 50; and R2 is H or a is C1 to C4 aliphatic hydrocarbyl or acyl, are used as fabric conditioners in CO2 based dry cleaning systems. The cleaning medium may include detergent surfactant and/or non surfactant cleaning additive or may be free from such additives in which case the treatment can be provided in a rinse cycle in a cleaning process.

Abstract: Cleaning media based on liquid CO2 and including from 0.01 to 5% by weight of the formulation of a cleaning additive which is at least one C6 to C24 hydrocarbyl ester of a multi-carboxylic acid can be used in dry cleaning of textiles. Desirable cleaning additives are of the formula (I): R1(CO2R2)n where R1 is the residue of a C1 to C10 hydrocarbyl group from which n hydrogen atoms have been removed, R2 is a C6 to C24 hydrocarbyl, particularly alkyl or alkenyl, group; and n is from 2 to 5; particularly C12 to C18 adipate esters.
