Feminine anti-itch cloth
The present invention provides disposable cloths that are designed to reduce itching discomfort when wiped across the vulvar tissue. These disposable cloths are wetted with a composition that includes at least one anesthetic, protectant, buffer, and surfactant. The composition is substantially clear and preferably does not bring about a cooling or stinging sensation when applied to the vulvar tissue. Furthermore, the composition has a pH adapted to vulvar use.

a cloth wetted with a composition,
the composition comprising:
water,
an anesthetic,
from 5 to 45% of a protectant,
a buffer, and
a surfactant,
where the composition excludes quantities of chemesthetic ingredients sufficient to provide a cooling effect when applied to vulvar tissues.
2 . The cloth of claim 1 , where the composition has a turbidity of from 0.1 to 1 NTU.
3 . The cloth of claim 1 , where the composition has a turbidity of from 0.45 to 0.65 NTU.
4 . The cloth of claim 1 , where the composition has a pH of from 3.4 to 3.9.
5 . The cloth of claim 1 , where the composition has an average pH of about 3.7.
6 . The cloth of claim 1 , where the surfactant comprises less than 10% of the composition.
7 . The cloth of claim 1 , where the surfactant comprises less than 5% of the composition.
8 . The cloth of claim 1 , where the composition comprises at most 0.015% chemesthetic cooling ingredients.
9 . The cloth of claim 1 , where the anesthetic is selected from the group consisting of pramoxine, benzocaine, dibucaine, tetracaine, resorcinol, and mixtures thereof.
10 . The cloth of claim 1 , where the anesthetic comprises from 0.5 to 20% of the composition.
11 . The cloth of claim 1 , where the anesthetic comprises from 0.9 to 1.1% of the composition.

13 . The cloth of claim 1 , where the protectant comprises glycerin.
14 . The cloth of claim 1 , where the protectant comprises from 10 to 40% of the composition.
15 . The cloth of claim 1 , where the protectant comprises from 20 to 40% of the composition.
16 . The cloth of claim 1 , where the buffer is selected from the group consisting of citric acid/sodium citrate, benzoic acid/sodium benzoate, acetic acid/sodium acetate, and mixtures thereof.
17 . The cloth of claim 1 , where the buffer comprises from 0.1 to 1% of the composition.
