Abstract
Many people who suffer from anal rectal discomfort and disorders need fibrous sheet materials which are pre-moistened with a solution for improved cleansing without excessive skin irritation. The invention particularly concerns wet wipes, such as anal-rectal wipes, which comprises a solution comprising hamamelis water or witch hazel, to effectively treat anal-rectal disorders.
Core Innovation
The invention provides a wet wipe for cleansing skin that comprises a fibrous sheet material and an aqueous-based formulation. The aqueous-based formulation includes from about 10 to about 50 weight percent witch hazel, from about 0.01 to about 2 weight percent ethoxylated shea butter, and from about 0.01 to about 2 weight percent vitamin E acetate, where the weight percent is based on a total weight of the formulation.
The aqueous-based formulation is prepared by forming a side-phase and then mixing the side-phase into a main batch. In forming the side-phase, ethoxylated shea butter is melted at 50 degrees C. in a side-phase mixing vessel, and vitamin E acetate is added to the side-phase mixing vessel, where the ethoxylated shea butter and the vitamin E acetate are mixed to form the side-phase.
A method is also provided for manufacturing a wet wipe for cleansing skin by adding an effective amount of the aqueous-based formulation to a fibrous sheet material. The manufacturing method requires the same specified weight-percent ranges of witch hazel, ethoxylated shea butter, and vitamin E acetate, and the formulation is prepared by forming the side-phase and mixing the side-phase to a main batch at 25 degrees C. with vigorous mixing or vigorous shaking.
Claims Coverage
Two independent claims are present: one directed to the wet wipe composition and preparation, and one directed to the method of manufacturing the wet wipe. Together, the claims define three core inventive formulation elements and a two-stage preparation approach using a side-phase and a main batch at specified temperatures, with vigorous mixing or vigorous shaking.
Wipe composition with witch hazel, ethoxylated shea butter, and vitamin E acetate
A wet wipe comprising a fibrous sheet material and an aqueous-based formulation including from about 10 to about 50 weight percent witch hazel, from about 0.01 to about 2 weight percent ethoxylated shea butter, and from about 0.01 to about 2 weight percent vitamin E acetate, where the weight percent is based on a total weight of the formulation.
Side-phase preparation using melted ethoxylated shea butter and vitamin E acetate
The aqueous-based formulation is prepared by forming a side-phase by melting the ethoxylated shea butter at 50 degrees C. in a side-phase mixing vessel, adding the vitamin E acetate to the side-phase mixing vessel, and mixing the ethoxylated shea butter and the vitamin E acetate in the side-phase mixing vessel.
Main batch mixing at 25 degrees C. with vigorous mixing or vigorous shaking
After forming the side-phase, the side-phase is mixed to a main batch at 25 degrees C. with vigorous mixing or vigorous shaking.
Manufacturing by adding an effective amount to a fibrous sheet material
A method of manufacturing a wet wipe for cleansing skin by adding an effective amount of an aqueous based formulation to a fibrous sheet material, wherein the aqueous based formulation comprises the specified weight-percent ranges of witch hazel, ethoxylated shea butter, and vitamin E acetate, and is prepared by forming the side-phase and mixing to a main batch as specified.
Claim coverage centers on an aqueous-based formulation containing specified weight-percent ranges of witch hazel, ethoxylated shea butter, and vitamin E acetate, together with a side-phase to main batch preparation approach using specified temperatures and vigorous mixing or shaking.
