Abstract:
Formalin is a 37 5pg aqueous solution of formaldehyde gas and formaldehyde may be present in products as an active ingredient, preservative or contaminant. This contamination may be from the container, the package material or in situ formation by degradation of the formaldehyde releasers. The free formaldehyde content was determined in the 50 kinds of Korean shampoos by quantitative analysis recently described, the lutidine method, which is simple, rapid and used for colored products which cannot be analysed by the chrornotropic acid method. Formaldehyde has been found in 46 out of the 0 samples, i.e., 90g., and the concentration ranged from 0. 1 to 78. 6 pg/ml(0. 1 78. 6 ppm).
