    Abstract: A process for removing contaminants from the surface of a substrate comprises contacting the substrate with a cleaning composition comprising at least one mono-, di-, or trialkoxy-substituted perfluoroalkane, perfluorocycloalkane, perfluorocycloalkyl-containing perfluoroalkane, or perfluorocycloalkylene-containing perfluoroalkane compound, the compound optionally containing additional catenary heteroatoms. The compounds exhibit good solvency properties while being environmentally acceptable.

    Abstract: The invention is directed to a dry-cleaning article suitable for use in the home. The article is characterized by a sheet that is permeated with a composition including 51-98% by weight of organic solvent such as paraffins, olefins, acetylenes or mixtures thereof, 1-35% by weight of water, and 1-14% by weight of emulsifier to allow the water to be uniformly mixed into the solvent. The composition can also include 1-5% by weight of perfume for scenting clothing, and 1-5% by weight of nonionic and/or anionic surfactant to provide additional stain removal capability of the composition. The invented composition is thus organic-solvent-based and is particularly effective to remove body or cosmetic oil stains from garments. The invention is also directed to the composition and methods for using the sheet in a drying machine.

    Abstract translation: 本发明涉及适合在家中使用的干洗制品。 该制品的特征在于用包含51-98重量％的有机溶剂如石蜡，烯烃，乙炔或其混合物的组合物，1-35重量％的水和1-14重量％的组合物渗透的片材 的乳化剂，以使水均匀地混合到溶剂中。 该组合物还可以包括1-5重量％的用于香味的香料的香料和1-5重量％的非离子和/或阴离子表面活性剂以提供组合物的附加的去污能力。 因此，本发明的组合物是有机溶剂型的，并且特别有效地从衣物中除去身体或化妆油污渍。 本发明还涉及在干燥机中使用该片材的组合物和方法。

    Abstract: The present invention is directed to a novel single, unit-dose drycleaning article in which at least a portion thereof dissolves in a drycleaning solvent during the drycleaning cycle for releasing a premeasured amount of a drycleaning additive contained within the article. The single, unit-dose drycleaning article is generally in the form of a sealed tub formed of a polystyrene. The unit-dose tub preferably dissolves within about one minute after being in contact with the drycleaning solvent to ensure release and adequate mixing of the drycleaning additive with the drycleaning solvent to effect maximum drycleaning results. In an alternative form, the single, unit-dose drycleaning article may be partially formed with a material that dissolves in a drycleaning solvent. In that form, it is preferred to locate the single, unit-dose drycleaning article in a sealable enclosure, such as a sealable bag, net or basket, which is formed of a material that is drycleaning solvent-insoluble, drycleaning solvent-permeable, such as a polyethylene, polypropylene, nylon, polyester, cotton, metal, etc., so that the remaining or non-dissolved portion of the single, unit-dose drycleaning article can be retrieved at the end of the drycleaning cycle.

    Abstract translation: 本发明涉及一种新颖的单一单位剂量干洗制品，其中至少一部分在干洗清洗循环期间溶解在干洗清洁溶剂中，以释放预先测量的量的包含在制品内的干洗添加剂。 单个单位剂量干洗制品通常是由聚苯乙烯形成的密封桶的形式。 单位剂量桶优选在与干燥清洁溶剂接触后约1分钟内溶解，以确保干燥清洁添加剂与干燥清洁溶剂的释放和充分混合，以实现最大的干洗效果。 在替代形式中，单个单位剂量干洗制品可以部分地形成有溶解在干洗清洁溶剂中的材料。 在该形式中，优选将单个单位剂量干洗制品定位在可密封的外壳中，例如可密封的袋，网或篮，其由干溶剂不溶的干燥清洁溶剂可渗透的材料形成， 例如聚乙烯，聚丙烯，尼龙，聚酯，棉花，金属等，从而可以在干燥清洗循环结束时取出单一单位剂量干洗制品的剩余或非溶解部分。
