Abstract

A solution for urushiol induced contact dermatitis is provided for in a topical solution. According to the invention, a method is provided for applying a composition of substances to the affected area, working the composition into the affected area, and removing the composition from the affected area. The composition comprises at least one ethoxylate in combination with a supporting agent. It is believed that this combination binds to the available urushiol receptors rendering it inactive. The affinity of the receptors for the ethoxylates also appears to cause a release of the urushiol from its epidermal bonds for bonding to the composition. An inert scrubbing agent, such as polyethylene beads, can also be included to assist in the release of the urushiol. Acetylated lanolin alcohol, EDTA, a foam stabilizer, and water can also be added to the composition without effecting performance.

Claims

1. A method for treating urushiol induced contact dermatitis, comprising the steps of:

providing an aqueous topical composition comprising nonoxynol-9;

sodium lauroyl sarcosinate; and

water;

applying the composition to an affected area;

permitting the composition to remain on the affected area a sufficient amount of time to enable the composition to cause an effect; and

removing the composition from the affected area.

2. The method of claim 1, wherein the step of providing an aqueous topical composition comprising nonoxynol-9;

sodium lauroyl sarcosinate; and

water further comprises the step of providing acetylated lanolin alcohol.

3. The method of claim 1, wherein the step of providing an aqueous topical composition comprising nonoxynol-9;

sodium lauroyl sarcosinate; and

water further comprises the step of providing polyethylene granules or pumice.

4. The method of claim 1, wherein the step of providing an aqueous topical composition comprising nonoxynol-9;

sodium lauroyl sarcosinate; and

water further comprises the step of providing EDTA.

5. The method of claim 1, wherein the step of providing an aqueous topical composition comprising nonoxynol-9;

sodium lauroyl sarcosinate; and

water further comprises the step of providing a foam stabilizer.

6. A method for treating urushiol induced contact dermatitis, comprising the steps of:

providing an aqueous topical composition comprising nonoxynol-9;

sodium lauroyl sarcosinate;

water; and

polyethylene granules or pumice; and

pumice;

applying the composition to an affected area;

permitting the composition to remain on the affected area a sufficient amount of time to enable the composition to cause an effect; and

removing the composition from the affected area.

7. The method of claim 6, wherein the step of providing an aqueous topical composition comprising nonoxynol-9;

sodium lauroyl sarcosinate;

water; and

sodium lauroyl sarcosinate;

polyethylene granules or pumice;

acetylated lanolin alcohol;

water;

EDTA; and

a C12–

15 pareth-9;

applying the composition to an affected area;

permitting the composition to remain on the affected area a sufficient amount of time to enable the composition to cause an effect; and

removing the composition from the affected area.
