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.
1 . An anti-itch cloth, for treating itching of the vulvar tissues, comprising:
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.
12 . The cloth of claim 1 , where the protectant is selected from the group consisting of glycerin, dimethicone, and mixtures thereof.
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.
18 - 20 . (canceled)
21 . A composition for treating vulvar tissue, consisting essentially of:
water,
an anesthetic,
from 5 to 45% of a protectant,
a preservative,
a buffer, and
a surfactant.
22 - 28 . (canceled)
29 . A method of forming an anti-itch cloth for treating itching of the vulvar tissues, comprising:
wetting a cloth with an anti-itch composition comprising:
water,
an anesthetic,
from 5 to 45% of a protectant,
a buffer, and
a surfactant, where the composition excludes quantities of ingredients sufficient to provide a cooling effect when applied to vulvar tissues.
30 - 40 . (canceled)
41 . A method for treating vulvar discomfort, comprising:
contacting vulvar tissue with a cloth wetted with an anti-itch 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.
42 - 47 . (canceled)
48 . The anti-itch cloth of claim 1 , where the surfactant is the sole surfactant.
49 . The anti-itch cloth of claim 1 , where the composition forms no stable foams.
50 . The composition of claim 21 , where the surfactant is the sole surfactant.
51 . The composition of claim 21 , where the composition forms no stable foams.
52 . The method of claim 29 , where the surfactant is the sole surfactant.
53 . The method of claim 29 , where the composition forms no stable foams.
54 . The method of claim 41 , where the surfactant is the sole surfactant.
