    • Petrolatum based compositions (i.e., composition in which the emollient petrolatum comprises greater than or equal to 50% of the composition) are desirable because of the excellent moisturization properties provided by petrolatum. However, it has sensory negatives perceived by consumers. Specifically, because of the oily/greasy and "tacky" (i.e., slightly adhesive or gummy to touch) feel, petrolatum has certain limits to the scope of application. We have found a way to overcome this problem using a copolymer which furthermore avoids the undesirable use of additional oil. A composition is therefore provided comprising: i) 50% to 99.95 % by weight petrolatum; ii) greater than 0.05% by weight of a copolymer bearing greater than 70% long chain alkyl. said composition having an enthalpy of between 30 and 65, preferably 40 and 60, even more preferably 45 and 55 J/g, the petrolatum number average crystal size being less than 10 µm, preferably less than 5 µm, more preferably less than 1 µm.
    • 由于由凡士林提供的优异的保湿性,基于凡士林的组合物(即其中软化矿脂含有组合物的50%以上的组合物)是理想的。 但是,它有消费者感觉到的感官消极。 具体来说,由于油性/油腻和“发粘”(即轻微粘合或粘合触觉)的感觉,凡士林对适用范围有一定的限制。 我们已经找到了一种使用共聚物来克服这个问题的方法,这进一步避免了不期望使用另外的油。 因此,提供了一种组合物,其包含:i)50%至99.95%重量的凡士林; ii)大于0.05重量%的具有大于70%长链烷基的共聚物。 所述组合物的焓为30至65,优选为40至60,甚至更优选为45和55J / g,凡士林的数均晶体尺寸小于10μm,优选小于5μm,更优选小于1μm 。
