Abstract: A composition that describes a clear, colorless, odorless, aqueous solution that is safe and effective in restoring and maintaining normalcy of the keratinous tissues and the adjacent tissues of finger and toe nails and equine hooves. Cracking, splitting, peeling and breakage of nails and hooves caused by environmental factors that denature peptide bonds of keratin, interrupts water and lipid balance and further interrupts growth and normal metabolic processes, is stopped and compositional balance is re-established by application of the solution. The composition is effective for keratinous tissues that are either too dry or too wet. Application by dropper bottles or sprays is quick, easy and not messy. Beneficial effects are observed in 1-2 weeks and reinforcement treatments are required only once or twice per week, or as required to maintain normal status.
