Overview
Artificial Perspiration
The artificial Eccrine Sweat we offer is a stabilized ready to use solution. It consists of the 19 amino acids, the seven most abundant minerals and the four most abundant metabolites at a pH of 4.5. All concentrations closely match experimentally determined values for adult human Eccrine Sweat. Custom formulations are available on request.
Pickering Laboratories is now pleased to offer our Artificial Eccrine Perspiration in a larger format – in addition to the 200 mL and 5 mL quantities, we now offer our stabilized formulation in a 950 mL volume, packaged in a 1 L plastic eluent bottle.
Storage and Handling
The stabilized solution is preserved with a fungicide and bactericide for two years of shelf life.
The non-stabilized product is at a pH of 4.5 and kept frozen.

Buyers Guide
Artificial Perspiration Buyers Guide
Makers of smart watches, high performance textiles, biosensors, heads up displays, and fitness monitors all have one thing in common – the need to test their products for quality assurance. Personal electronics and wearable technology manufacturers perform sweat testing on materials including touch screens, watchbands, keyboards, eyeglasses, and any other product material or surface that would benefit from guaranteed reproducible results with artificial perspiration. By using Pickering Laboratories’ artificial eccrine perspiration, our customers are able to save time and ensure the same repeatable results anywhere, anytime.
Normally, a sweat mimic is prepared at the time of the test according to an industry specific formula. The American Society for Testing and Materials (ASTM) describes procedures to test many products in the presence of a sweat mimic. According to Michael Pickering, Founder/Owner of Pickering Laboratories, “we were guided by the multiplicity of such tests to develop an artificial perspiration that can yield reproducible results independent of the test.”
Pickering Artificial Eccrine Perspiration is the closest mimic available to actual eccrine perspiration, and we prepare two versions. The stabilized version has a preservative which prevents microbial growth and can then be stored at room temperature. The not stabilized version has no preservative and must be kept frozen until you intend to use it. You may need this version if you are testing a product that claims to prevent microbial growth or odor from perspiration. Our Artificial Eccrine Perspiration normally comes at pH 4.5, however, we can make it custom from pH 3.0 – 9.0.
