Abstract
Preparations containing methylsulfonylmethane (MSM) for administration to the skin, nails, other tissue and/or body fluids of a human or other animal subject are disclosed. Such compositions soften skin, strengthen nails and provide other benefits when applied topically. And, MSM compositions may also be administered orally, by injection and by inhalation.
In many instances, the effectiveness of MSM compositions is enhanced when such compositions contain carbamide (urea). Also, carbamide compositions are stabilized when they contain the MSM.
For topical administration, MSM compositions may be formulated in creams, lotions or gels which may be used alone or to serve as stable, neutral vehicles for other skin conditioning substances or therapeutically active drugs. Aqueous MSM solutions are suitable blood diluents.

9. A composition for topical application to the skin of a human or other animal subject comprising an aqueous solution of one to ten weight percent each of methylsulfonylmethane and carbamide in a combined amount such that the composition is capable of eliciting a physiological effect upon application of the composition, the ratio of methylsulfonylmethane to carbamide being such that the extent of the physiological effect is greater than the extent of the effect which results from application of an otherwise identical composition containing only one of said methylsulfonylmethane and carbamide in an amount equal to said combined amount.

10. In a chemical composition containing carbamide, an amount of methylsulfonylmethane effective to retard decomposition of the carbamide.
- 11. A method for altering the condition of tissue and/or body fluids of a human or other animal subject comprising concurrently topically administering to the subject one to twenty weight percent methylsulfonylmethane and an amount of carbamide in the range of one to twenty weight percent effective to enhance the activity of the methylsulfonylmethane.
