Lipid-like substances incorporated in keratinized parts of the hair or appearing on its surface as sebaceous secretion act as detergents in water. At a sufficient concentration they decrease water surface tension to 0.03 N/m, and, contrary to widespread opinion, should contribute to fur wetting. The influence of these lipids on water surface tension markedly varies among both semiaquatic and land mammals, but in any case their natural concentration is too low to significantly affect the waterproof properties of the cover of the swimming animals.
掺入毛发角质化部分或作为皮脂分泌出现在毛发表面的类脂物质在水中起到洗涤剂的作用。在足够的浓度下，它们可将水的表面张力降低至0.03 N/m，并且与普遍观点相反，应该有助于毛发被水浸湿。这些脂质对水表面张力的影响在半水生和陆生哺乳动物中差异显著，但无论如何，它们的天然浓度都太低，无法显著影响水生动物体表的防水性能。
