Product Overview
Biochemazone Artificial Perspiration – Alkaline, Custom pH BZ156 is a ready-to-use, sterile alkaline artificial perspiration at pH 8.0 for the ISO textile perspiration tests. ISO 105-E04, colour fastness to perspiration, tests every specimen in two solutions – an acid one at pH 5.5 and an alkaline one at pH 8.0 – and rates the colour change and the staining of adjacent fabrics. ISO 105-B07 measures the colour fastness to light of textiles wetted with artificial perspiration. The alkaline solution of the method is the L-histidine / sodium chloride / disodium hydrogen phosphate solution at pH 8.0, representing perspiration that has aged on the skin.
The Custom pH version is supplied at the method pH 8.0 or, on request and at no extra cost, at any pH from 2 to 9 – for buyer specifications and in-house methods that set their own pH on the ISO sweat base. State the pH in the order notes. It is supplied not stabilized and preservative-free, with a 6-month shelf life unopened. The stabilized custom-pH version is BZ158.
The acid solution that completes the ISO 105-E04 pair is BZ155. Prepared with ISO 3696 compliant high-purity water under Biochemazone’s ISO 9001 / GMP quality system, every batch is standardised for composition and pH so that grey-scale ratings are reproducible between laboratories. BZ156 is used by textile mills, dye houses, garment brands and third-party laboratories; a dry kit for both solutions is BZ580 and bulk carboys are BZ581.
