  Grease compositions are provided that can have one or more unexpectedly beneficial low temperature properties even though the grease compositions are formed from lower value components that traditional low temperature greases. The unexpectedly beneficial low temperature properties can be achieved in part by grease compositions that include a naphthenic base stock having a viscosity index of roughly 120 or less and/or a pour point of −20° C. or more while having a naphthenes content of 60 wt % or more. In some aspects, the naphthenic base stock can have an aromatics content of 20 wt % or less.

  所提供的润滑脂组合物具有一种或多种意想不到的有益低温特性，即使这些润滑脂组合物是由比传统低温润滑脂价值更低的成分形成的。这些出乎意料的有益低温特性可部分通过润滑脂组合物来实现，该组合物包括一种环烷基础油，其粘度指数约为 120 或更低和/或倾点为 -20°C 或更高，同时环烷烃含量为 60 wt % 或更高。在某些方面，环烷基础油的芳烃含量可为 20 wt % 或更低。

  A cosmetic composition for use in cleansing and conditioning the skin of the hand, fac, heels/knees/elbows and/or body of a human being that comprises (A) 35% to 80% by weight of emollient material; (B) a water-soluble surface active agent in a proportion selected from the range of 0.4% to 8.0% by weight, said proportion being effective to deposit a skin softening amount of emollient material on the treated skin without a greasy after-feel when said composition is applied to and rinsed from the skin with water and the skin is dried; and (C) a water-insoluble C12-C18 monocarboxylic acid salt, the weight ratio of said emollient material to said carboxylic acid salt being in the range of about 7:1 to about 1:1 and being adequate to produce a composition in the form of a substantially stable, extrudable paste or cream; said composition being effective to cleanse, soften, smooth and moisturize the skin when the composition is applied to and massaged into the skin, thereafter rinsed from the skin with water and the skin is dried. Further, the addition of 5% to 50% by weight of a non-irritating, mildly abrasive, skin compatible, particulate material that is effective to cleanse the skin without abrading the skin to the foregoing composition produces a temperature stable, cosmetic composition particularly suitable for exfoliating the dead skin cells while conditioning the skin at the same time. The described invention also includes the method of cleansing and conditioning the skin of the hands, face, heels/knees/elbows and/or the body of a human being that comprises the steps of (I) applying the above-identified cosmetic compositions to the area of the body to be conditioned; (II) massaging said composition into or onto the skin of said area with the hands; (III) rinsing the composition from the treated skin area with clear, tepid water; and (IV) drying said treated area by patting with a towel; said method being effective to deposit a film of emollient material on the skin thereby smoothing, softening and moisturizing said skin.

  一种用于清洁和调理人的手、面部、脚跟/膝盖/肘部和/或身体皮肤的化妆品组合物，包括 (A) 35% 至 80% （按重量计）的润肤剂材料；(B) 比例选自 0.4% 至 8.0% （按重量计）的水溶性表面活性剂。(C) 不溶于水的 C12-C18 单羧酸盐，所述润肤剂材料与所述羧酸盐的重量比在约 7：1至约1:1的范围内，并足以制成基本稳定、可挤出的膏状或乳状的组合物；当将所述组合物涂抹到皮肤上并按摩皮肤，然后用水从皮肤上冲洗干净并将皮肤干燥时，所述组合物可有效地清洁、软化、光滑和滋润皮肤。此外，在上述组合物中添加 5%-50%（按重量计）的无刺激性、轻度研磨性、皮肤相容性的微粒材料，可有效清洁皮肤而不会磨损皮肤，从而产生一种温度稳定的化妆品组合物，特别适用于去除死皮细胞，同时调理皮肤。所述发明还包括清洁和调理人的手、脸、脚跟/膝盖/肘和/或身体皮肤的方法，该方法包括以下步骤 (I) 将上述化妆品组合物涂在需要调理的身体部位；(II) 用手将所述组合物按摩到所述部位的皮肤上； (III) 用清澈的温水冲洗处理过的皮肤部位上的组合物；以及 (IV) 用毛巾拍干处理过的部位；所述方法可有效地在皮肤上形成一层润肤物质薄膜，从而平滑、软化和滋润所述皮肤。
