The present article describes a reproducible method for determining the photostability of sunscreen products. This method is based in part on the in vitro determination of the UVA protection factor as proposed by Colipa for the irradiation aspect, and on the spectroscopy of a sunscreen in dilute solution for the absorbance measurement aspect.

The Interagency Coordinating Committee on the Validation of Alternative Methods (ICCVAM) has recommended a non-animal test method to identify estrogen agonist and antagonist activity. In addition to recommending the test, ICCVAM also found the method to provide a number of benefits over the method currently employed in the United States.

To evaluate the comprehensive effects of shine and color intensity in hair, a hair color vibrance factor has been developed to enable new claims for hair dye formulas and after-dye treatments. Experimental results described here show how varying the ingredients in shine spray and hair dye formulas affect this factor and correlate with subjective panelist assessments.

Today, product formulation goes hand in hand with efficacy testing, but nearly 40 years ago, when Sergio Nacht, PhD, started out in the personal care industry, it was a different story. Throughout his decades in personal care, Nacht has developed methodologies that have allowed the personal care industry to establish efficacy of a product and convey this to the consumer. He has also been instrumental in the increased efficacy of personal care products through sustained release.

When formulating a hair care product, there is often a need for testing that validates the product’s technical performance. This testing provides guidance to create formulas with appropriate performance, while also communicating the product’s message to the consumer. This article discusses the use of instrumental combing measurements when formulating hair conditioning products.

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.
