    • The invention relates to non-ozone depleting cleaning compositions for degreasing elements in manufacturing and engineering processes like oily machine parts and for defluxing printed circuit boards, used in the electric and electrical industry. The composition according to the invention contains at least one C.sub.6-12 alkyllactate ester, preferably 2-ethyl hexyl lactate, in an amount of 70-99% by weight and at least one emulsifier, preferably n-octanol, in an amount of 1-30% by weight. One of the main advantages of the present cleaning composition is based on the fact that in the rinsing step with water for removing the cleaning composition from the treated surface an emulsion is formed, which on the one hand is stable enough for having proper rinsing ability and on the other hand--after the rinsing step--will separate rather quickly into an oil and a water phase. This last mentioned phenomenon provides the benefits of reusing the active cleaning agent, i.e. the C.sub.6-12 alkyllactate ester and reusing and/or partly discarding the waste water being toxicologically and environmentally safe.
    • 本发明涉及用于在电气和电气工业中使用的制造和工程过程中的脱脂元件的无臭氧消耗清洁组合物,例如油性机器部件和用于去焊的印刷电路板。 根据本发明的组合物含有至少一种70-99重量%的C 6-12烷基乳酸酯,优选2-乙基己基乳酸酯,和至少一种乳化剂,优选正辛醇,其量为1- 30重量%。 本发明清洁组合物的主要优点之一是基于以下事实:在用于从处理过的表面除去清洁组合物的水的漂洗步骤中,形成乳液,这一方面足够稳定以具有适当的漂洗能力和 另一方面,在漂洗步骤之后,将相当快地分离成油和水相。 这最后提到的现象提供了重新使用活性清洁剂即C6-12烷基乳酸酯并且重新使用和/或部分地废弃在毒理学和环境上安全的废水的益处。

    • Stable aqueous fabric softening compositions based on water-dispersible cationic fabric softeners such as the di-long chain, di-short chain quaternary ammonium salts are provided using synergistic proportions of fatty alcohols to enhance the softening performance. Both concentrated and ready-for-use formulations can be prepared. The active ingredients concentration in the concentrated formula is generally in the range of 11 to 20% by weight while for the ready-for-use formulations, concentration of the active ingredients may range from about 3 to about 8% by weight. In either case, the weight ratio of cationic softening agent to fatty alcohol being in the range of from about 4.5:1 to 3.5:1. These compositions have low viscosity and are easily dispersible in cold water and are storage stable. Water soluble electrolytes can further reduce viscosity and ethoxylated amines can further increase stability. Methods for making the compositions are also disclosed.
    • 使用协同比例的脂肪醇提供基于水分散性阳离子织物软化剂如二长链,二短链季铵盐的稳定的水性织物柔软组合物,以提高软化性能。 可以制备浓缩和即用型制剂。 浓缩配方中的活性成分浓度通常在11至20重量%的范围内,而对于即用型制剂,活性成分的浓度可以为约3至约8重量%。 在任一情况下,阳离子软化剂与脂肪醇的重量比在约4.5:1至3.5:1的范围内。 这些组合物具有低粘度并易于分散在冷水中并且储存稳定。 水溶性电解质可进一步降低粘度,乙氧基化胺可进一步提高稳定性。 还公开了制备组合物的方法。
