The present invention relates to a substantially dry, disposable personal care article suitable for cleansing, said article comprising:
a) a water insoluble substrate comprising a creped nonwoven layer; and
b) a cleansing component disposed adjacent to said creped nonwoven layer, wherein said component comprises from about 10% to about 1000%, by weight of the water insoluble substrate, of a lathering surfactant
and wherein the cleansing component exhibits a log [(&eegr; @ 25° C.)/(&eegr; @ 200° C.)] greater than about 0.45.
Additionally, the present invention relates to a similar article that is characterized by a cleansing component that exhibits a complex viscosity measured under an oscillation stress of 1 Pa of greater than about 100 Pa·s. at 25° C. The present invention further relates to a substantially dry, disposable personal care article suitable for conditioning wherein the above-described article comprises a therapeutic benefit component, disposed adjacent to said water insoluble substrate, wherein said component comprises from about 10% to about 1000%, by weight of the water insoluble substrate, of a therapeutic benefit component in addition to or in lieu of the cleansing component.
These articles have been found to be particularly useful for personal cleansing applications, namely for the skin and hair. Thus, the present invention further relates to methods of cleansing and conditioning the skin and hair utilizing the articles of the present invention.
本发明涉及一种适用于清洁的基本干燥、一次性个人护理用品,该用品包括:
a)一种水不溶性基材,包括一个褶皱无纺布层;和
b)位于所述褶皱无纺布层相邻的清洁成分,其中所述成分包括从水不溶性基材的重量约10%到约1000%的起泡表面活性剂,且所述清洁成分的对数[(&eegr; @ 25℃)/(&eegr; @ 200℃)]大于约0.45。
此外,本发明还涉及一种类似的用品,其特征在于清洁成分在25℃下测量的振荡应力大于约100 Pa·s的复杂黏度。本发明进一步涉及一种适用于调理的基本干燥、一次性个人护理用品,其中上述所述的用品包括治疗益处成分,位于所述水不溶性基材相邻的位置,其中所述成分包括从水不溶性基材的重量约10%到约1000%的治疗益处成分,除了或代替清洁成分。
已经发现这些用品在个人清洁应用中特别有用,即用于皮肤和头发。因此,本发明还涉及利用本发明的用品清洁和调理皮肤和头发的方法。
