Hydrosal Gel is a brand name for a first-line topical gel treatment for excessive sweating. The product is a registered trademark of Valeo Pharma Inc. Hydrosal Gel contains 15% aluminum chloride hexahydrate, an ingredient often used in strong antiperspirants, as well as a hydroalcoholic salicylic acid gel base.
Hydrosal Gel has a low risk of irritation due to its proprietary gel base. Clinical studies have demonstrated that the gel vehicle is better tolerated than an alcohol solution most commonly found in other products for excessive sweating, resulting in less irritation. In addition to decreasing perspiration, Hydrosal Gel reduces odours. Clinical studies support the efficacy and low incidence of irritation of the 15% aluminum chloride and 2% salicylic acid gel base formula.
