Yield Stress Measurements for Personal Care, Part I: Definitions and Basics

The aim of this article series is to properly define and differentiate yield stress from high viscosity, as well as develop a method for assessing whether a sample has a yield stress. In addition, it will illustrate how to determine the amount of yield needed for a given application.

Free Formaldehyde Preservative Stability in Personal Care: Part II—Formulations

As scrutiny of formaldehyde-donor (FD) and other preservative technologies has increased in recent years, additional assurances of the relative safety and benefits of FD technologies are required. This two-part article examines the effects of temperature and pH on free-formaldehyde levels (as detected by C-13 NMR), first in water, then in personal care formulations.
