Product Overview
Biochemazone Simulated Perspiration or Artificial Perspiration, Custom pH – Stabilized BZ129 is a ready-to-use, sterile artificial sweat made to the pH you specify, anywhere from 2 to 9, at no extra cost. Human sweat ranges from distinctly acidic to mildly alkaline depending on body site, activity and time on the skin, and many in-house and customer test methods specify a pH that no published standard solution matches – BZ129 is made for those methods.
The solution contains amino acids, minerals and metabolites that simulate the composition and properties of human eccrine sweat. It is stabilized with a preservative / stabilizer system so that it stays free of microbial growth through repeated opening and has a 1-year shelf life unopened. State the required pH in the order notes or by email; a not-stabilized (preservative-free) version and a Powder Version Kit are available on request.
Prepared with ISO 3696 compliant high-purity water under Biochemazone’s ISO 9001 / GMP quality system, every batch is adjusted and checked at the pH ordered. For fixed-pH standard solutions see AATCC TM15, pH 4.3 BZ148, BS EN 1811, pH 6.5 BZ120 and ISO 3160-2, pH 4.7 BZ124.

Frequently Asked Questions
How do I tell you the pH I need?
Write the pH in the order notes at checkout, or email info@biochemazone.com with your order number. If no pH is given we will contact you before the order is prepared.
Can I order several pH values?
Yes. Order one bottle per pH and list the values in the order notes – for example pH 4.5, 5.5, 6.5 and 8.0 for a pH series.
