Description

FAST ACTING ITCH RELIEF COOLING SPRAYCROSS-REFERENCE TO RELATED APPLICATIONS

[0001] This application claims priority to U.S. Provisional Application 63 / 623,538 (filed on January 22, 2024) which is incorporated by reference in its entirety.FIELD OF THE INVENTION

[0002] This disclosure relates to a fast acting itch relief and cooling sprays containing hydrocortisone, Aloe vera, and a cooling agent. The disclosure also relates to using these sprays to relieve itch and cool areas of affected skin.BACKGROUND OF THE INVENTION

[0003] According to the Mayo Clinic, itchy skin is an irritating sensation that makes one want to scratch. It is also called pruritus. Often itchy skin is caused by dry skin and is more common in older adults due to skin becoming drier with age. Treatment of itchy skin focuses on removing the cause of the itch.

[0004] Common itch treatments involve locally applying a corticosteroid, such as e.g., hydrocortisone. Hydrocortisone can be applied as an ointment or in other forms. However, regardless of how hydrocortisone is applied, the hydrocortisone only provides a delayed itch relief. It does not provide an immediate cooling or soothing sensations to areas of itchy skin which are often warmer.

[0005] To improve the relief provided by hydrocortisones, hydrocortisone has been formulated as spray formulations. U.S. Patent No. 3,456,052 discloses aerosol compositions containing butoxymonoether of a polyoxyalkylene glycol. These compositions can contain a medicament such as thimerosal, bacitracin, benzocaine, lidocaine, hydrocortisone, neomycin sulfate, penicillin, tetracycline, polymixin B sulfate, and mixtures thereof. A private label is currently selling a 1% hydrocortisone spray that offers itch relief. However, these spray formulations, while providing itch relief, fail to provide cooling or soothing benefits.

[0006] What is needed is a localized treatment that allows for localized itch relief and that provides cooling and soothing benefits.SUMMARY OF THE INVENTION
