Rapid Colorimetric Analysis of para-Phenylenediamine in Henna-based, Non-permanent Tattoo Color Mixtures
By: Christopher T. Krüger; Dirk W. Lachenmeier, Ph…
In some henna mixtures, para-phenylenediamine (PPD) has illegally been added and it is responsible for complications such as allergic contact dermatitis. While high-performance liquid chromatography has previously been used to detect PPD, a colorimetric method that is faster and portable, described here, has been developed. For product developers, this method can be used to evaluate henna plant extracts.

Although cellulite is not considered a disease, it is a significant cosmetic problem for many post-adolescent women. Recent studies using new diagnostic techniques such as ultrasound imaging can define the cellulite-reducing efficacy of cosmetics. However, there is still a need to standardize and objectify the testing procedures and to find parameters to measure anti-cellulite efficacy.

Methods for determining SPF in vivo are based on a biological response by human skin. To overcome intrinsic variation in these methods, large numbers of volunteers and statistics are required; however, these concepts are often poorly understood or worse, misinterpreted. This article discusses how these values should be interpreted and explains what they mean to formulators.

A sunscreen layer’s thickness is critical to its SPF. However, current regulations specify a mass application rate for testing, rather than a volumetric application rate. This significantly underrates the SPF values of mineral sunscreens due to their higher densities since, compared with their relative organic counterparts, thinner films are being tested, as will be shown here.
