适用于任何和所有这些应用的组合物都在本发明的范围内。在一些情况下，组合物是漆或其他涂料。在这样的情况下，组合物还可以包含粘结剂，任选地颜料和任选地一种或多种常规添加剂(例如，以改变表面张力、改善流动性、改善成品外观、增加湿边、改善颜料稳定性等——这样的添加剂是本领域已知的)。组合物可以包含水性溶剂或有机溶剂以适应目的。
组合物还可以用于医疗应用，例如用于涂覆包括医疗装置的设备。
在一些情况下，组合物是药物组合物。换句话说，组合物可以包含如本文所述的内酰胺和药学上可接受的赋形剂。组合物可适用于局部使用(例如它可以是霜剂或洗剂)，它可适用于眼部使用(例如它可以用作药物滴眼剂)，它可适用于耳朵使用(例如它可以用作滴耳剂)，它可适用作漱口剂，或它可适用于口服施用。
在一些情况下，组合物是适用于家庭(通常被称为家庭护理组合物)或机构的组合物。家庭护理组合物包括但不限于清洁产品、洗衣洗涤剂和织物调理剂。在一些情况下，组合物是家庭护理组合物，例如洗衣液。因此组合物可以包含洗涤表面活性剂和助洗剂。组合物可以是织物调理剂(也被称为织物柔顺剂)并且可以包含抗静电剂。组合物也可以是家庭清洁产品。
在一些情况下，组合物是个人护理组合物。例如，组合物可以旨在用于皮肤上(例如霜剂、清洁剂或浆液)。例如，组合物可用于痤疮的预防和治疗。例如，组合物可以包含聚二甲基硅氧烷、凡士林、保湿剂(例如透明质酸或甘油)和神经酰胺中的一种或多种。在一些情况下，组合物是包含洗涤剂的个人护理组合物，例如，组合物可以是洗脸或沐浴凝胶或洗发香波。组合物可以是除香波以外的毛发处理组合物。组合物可以是除臭组合物(例如，除臭粉末、糊剂或液体)。组合物可以是口腔护理组合物(例如牙膏或漱口水)，并且可以包含例如氟化物和/或调味剂。

组合物可以是适用于农业的组合物，例如作为土壤添加剂(固体或液体)。
组合物可以是适用于玻璃或透镜的处理或制造的组合物，例如作为用于太阳能电池板的添加剂/处理剂。
实施例
使用以下方法，使用超临界CO2，从由提供的JBR425的商业样品提取和纯化单鼠李糖脂和二鼠李糖脂。
将JBR425(来自)的商业样品与Celllite 载体混合并转移到超临界CO2提取器。增加温度和压力以产生超临界CO2，并且在脱脂步骤中从提取器移除残留的油和脂肪。然后在超临界CO2存在下将助溶剂(工业甲基化溶剂(IMS))加入到Cellite 载体上的剩余脱脂鼠李糖脂混合物中。以2.5％至10％的递增梯度引入助溶剂IMS以促进不同单鼠李糖脂和二鼠李糖脂比率的分离和移除。
制备以下结果中所示的水平的生物表面活性剂溶液以用于筛选。测试的最高水平取决于表面活性剂在水中的溶解度。以下代表性实施例使用4-(4-氯苯基)-5-亚甲基-吡咯-2-酮。
将固体内酰胺称量到配有0.45μm尼龙过滤器的Mini Uniprep样品小瓶中滤(每小瓶2.7至3.3mg)。将50μL的溶剂溶液放入每个样品小瓶中，给小瓶盖上盖子并用手轻轻振摇以摇动固体，然后放置于Thermo Labsystems平板摇床上并连续摇动48小时。此后，使用整体式滤过膜去除小瓶中的过量固体，并通过HPLC分析所得溶液以测定溶解的内酰胺的水平。
使用配有Hypersil Gold C18柱(15×2.1×3μm)的Agilent系列HPLC，使用流速为0.4mL/min的60/40甲醇/水(+0.1％甲酸)等度洗脱，使用DAD检测器在285nm分析样品。4-(4-氯苯基)-5-亚甲基-吡咯-2-酮的保留时间为约2.8分钟。
一式三份测试每个测试表面活性剂溶液，并计算溶液中的内酰胺的平均值。溶解度值被引用作为对单独的水的水溶性的改善(即，溶解在水+溶剂中的内酰胺的平均水平/溶解在水中的内酰胺的平均水平)以允许在不同天数进行筛选之间的比较。
发明人已经证实鼠李糖脂生物表面活性剂有益于增加水中的内酰胺溶解度，特别是在较低浓度下。最好的实施例是R2。
应理解的是，除非另有明确规定，否则所有的优选项是可以组合的。
