Abstract

Disclosed is an elastomeric article, such as an elastomeric glove, for example, that includes a coating on the skin-contacting surface of the article. The coating includes a carrier which may separate from the article at expected use conditions and may help to lubricate the skin. The coating also includes an additive which may provide a clinical benefit to the skin. The additive may be an emollient, a humectant, an anti-oxidant, or some other clinically beneficial additive.

Claims

1. An elastomeric article comprising:

a primary matrix comprising an elastomeric polymer and a skin-contacting surface; and

a coating composition applied to the skin-contacting surface, the coating composition comprising a clinically beneficial additive and a carrier.

2. The elastomeric article of claim 1, wherein the elastomeric polymer comprises a block copolymer.

3. The elastomeric article of claim 2, wherein the block copolymer is selected from the group consisting of styrene-isoprene-styrene block copolymers, styrene-polybutadiene-styrene block copolymers, styrene-butadiene block copolymers, styrene-ethylene butylene-styrene block copolymers, and mixtures thereof.

4. The elastomeric article of claim 1, wherein the carrier comprises a self-emulsifying wax.

5. The elastomeric article of claim 1, wherein the primary matrix is a natural rubber, a nitrile rubber, a polyurethane, or a neoprene.

6. The elastomeric article of claim 1, wherein the carrier comprises a quaternary ammonium compound having at least 20 carbon atoms.

7. The elastomeric article of claim 6, wherein the carrier comprises behenetrimonium methosulfate.

8. The elastomeric article of claim 1, wherein the beneficial additive is selected from the group consisting of an emollient, a humectant, an antioxidant, a neutralizing agent, a chelating agent, an anti-irritant, a vitamin, a skin conditioner, an alpha-hydroxy acid, a moisturizer, a beneficial botanical agent and an extract thereof, and a mixture thereof.

9. The elastomeric article of claim 1, wherein the beneficial additive comprises green tea extract.

10. The elastomeric article of claim 1, wherein the beneficial additive is chamomile or a chamomile extract.

11. The elastomeric article of claim 1, wherein the beneficial additive comprises allantoin.

12. The elastomeric article of claim 1, the coating composition further comprising a silicone polymer.

13. The elastomeric article of claim 12, wherein the silicone polymer comprises dimethicone.

14. The elastomeric article of claim 1, wherein the primary matrix comprises a base layer and a donning layer, wherein the skin-contacting surface of the primary matrix is an exterior surface of the donning layer.

15. The elastomeric article of claim 1, wherein the coating composition is anhydrous on the skin-contacting surface and comprises from about 80% to about 99% by weight carrier and from about 1% to about 20% by weight clinically beneficial additive.

16. The elastomeric article of claim 1, wherein the elastomeric article is a glove.

17. The elastomeric article of claim 16, wherein the coating composition is applied to the glove in an amount from about 0.001 to about 5 grams per glove.

18. The elastomeric article of claim 1, wherein the coating composition does not include Aloe vera.

19. An elastomeric glove comprising:

a primary matrix comprising an elastomeric block copolymer and a skin-contacting surface; and

a coating composition applied to the skin-contacting surface, the coating composition comprising a clinically beneficial additive, a silicone polymer, and a self-emulsifying wax comprising behenetrimonium methosulfate.

20. The elastomeric glove of claim 19, wherein the block copolymer is selected from the group consisting of styrene-isoprene-styrene block copolymers, styrene-polybutadiene-styrene block copolymers, styrene-butadiene block copolymers, styrene-ethylene butylene-styrene block copolymers, and mixtures thereof.

21. The elastomeric glove of claim 19, wherein the clinically beneficial additive is selected from the group consisting of an emollient, a humectant, and a mixture thereof.

22. The elastomeric glove of claim 19, wherein the beneficial additive comprises green tea extract.

23. The elastomeric glove of claim 19, wherein the beneficial additive is chamomile or a chamomile extract.

24. The elastomeric glove of claim 19, wherein the beneficial additive comprises allantoin.

25. The elastomeric glove of claim 19, wherein the silicone polymer comprises dimethicone.

26. The elastomeric glove of claim 19, wherein the primary matrix comprises a base layer and a donning layer, wherein the skin-contacting surface of the primary matrix is an exterior surface of the donning layer.

27. The elastomeric glove of claim 19, wherein the coating composition is an anhydrous composition and comprises from about 80% to about 99% by weight carrier, from about 1% to about 20% by weight clinically beneficial additive, and up to about 20% silicone polymer.

28. The elastomeric glove of claim 19, wherein the coating composition is applied to the glove in an amount from about 0.001 to about 5 grams per glove.

29. The elastomeric glove of claim 19, wherein the composition is applied to the elastomeric article as an aqueous composition, the aqueous composition comprising from about 0.1% to about 4% by weight of the carrier, from about 0.1% to about 4% by weight of the silicone polymer, and from about 0.001% to about 20% by weight of the clinically beneficial additive.
