Abstract
The present disclosure is directed to alleviating the uncomfortable and unpleasant sensations that may accompany insertion and removal of personal care devices. Specifically, the present disclosure is directed to a personal care device that includes a moisture-activated composition that becomes lubricious only upon contact with moisture, such as from mucosal surfaces in the body.
Claims20
A tampon comprising a moisture-activated composition, wherein the composition comprises a hydrophobic carrier, a high molecular weight polymer having a molecular weight of between about 850,000 and 8,000,000 daltons;
- and C12-C15 Pareth-7.
A tampon comprising a moisture-activated composition, wherein the composition comprises a hydrophobic carrier, and a high molecular weight polymer having a molecular weight of between about 850,000 and 8,000,000 daltons;
- and wherein the low HLB surfactant is sorbitan monooleate.
A method of reducing the coefficient of friction during use of a tampon, the method comprising:
- applying a moisture-activated composition to the tampon, the composition comprising a hydrophobic carrier, and a high molecular weight polymer having a molecular weight of between about 850,000 and 8,000,000 daltons;
- and at least one surfactant selected from the group consisting of C12-C15 Pareth-7 and sorbitan monooleate;
- and
- contacting the tampon with a mucosal surface to activate the composition on the tampon, wherein upon contact, the coefficient of friction between the tampon and the mucosal surface is reduced.
A method of reducing the soiled appearance after removal of a tampon, the method comprising:
- applying a moisture-activated composition to a tampon, wherein the composition comprises a hydrophobic carrier;
- a high molecular weight polymer having a molecular weight of between about 850,000 and 8,000,000 daltons;
- and at least one surfactant selected from the group consisting of C12-C15 Pareth-7 and sorbitan monooleate;
- and
- contacting the tampon with a mucosal surface to activate the composition on the tampon;
- and
- removing the tampon, wherein upon removal, the soiled appearance of the tampon is reduced.
