Determining Korean Consumers’ Degree of Exposure to Lipstick and Face Creams
This study describes methods used in a Korean study to calculate consumer exposure to lipstick and face creams. The average amount applied daily was estimated and compared with data collected by weighing containers before and after use. The data collected was 1.8 to 1.6 times greater than the estimate, so although the survey represented real use patterns, the actual data was more accurate.

The Effect of Skin Metabolism on the Absorption of Chemicals
Skin expresses enzymes that can metabolize endogenous molecules but little is known regarding how they impact the delivery of xenobiotics. This review of recent works shows that skin metabolism alters the dermal absorption of lipophilic compounds, which opens new areas of investigation regarding the safety and efficacy of topically applied cosmetics.

Assessing the Impact of Hair Damage Types on Color Retention
This article reviews and assesses damage types caused to hair before and after artificial coloration, i.e., by bleaching, perming, heat treatment, UV exposure and shampooing, to compare how they impact color durability individually and combined. Formulation emerges as the key to designing shampoos that efficiently deliver actives to improve color protection against these and other damage types.

Influence of pH on the Preservative Boosting Effect of Chelating Agents
A system based on phenoxyethanol and ethylhexylglycerin (euxyl® PE 9010) from Schülke & Mayr is described here to boost the efficacy of preservatives. To substantiate its efficacy, the effects of the system were checked at pH levels of both 7.0 and 5.0.
