A particulate built nonionic synthetic organic detergent composition, useful for washing synthetic organic polymeric fibrous materials, such as polyesters and polyester-cotton blends and imparting to them soil release properties, while maintaining them comfortable to a wearer and not preventing vapour transmission through them, includes amounts of nonionic synthetic organic detergent, builder for such detergent, and a polymer of polyethylene terephthalate and polyoxyethylene terephthalate preferably of a molecular weight 15,000 to 50,000, made from polyethylene glycol and a polyoxyethylene glycol or similar material of a molecular weight 1,000 to 10,000 and in which the molar ratio of ethylene terephthalate to polyoxyethylene terephthalate units is in the range 2:1 to 6:1. Also disclosed are process for manufacturing such compositions and processes for washing laundry with them. |
