Numerous claims made in the popular press misrepresent the facts about formulations, and cosmetic science is not well-served by this. Here, the authors examine a number of such statements. The influence of skin creams and formulations on the penetration of actives must be communicated in a responsible manner to the public if the industry is to banish prevalent myths.

Formulators of personal care products for children are faced with the difficult task of creating products with maximum care and minimum risk, all while trying to be innovative. Infant skin is different from adult skin in many ways. First of all, it is characterized by a immature stratum corneum with a higher moisture content and looser structure, compared with adult skin.

This work evaluates the impact of temperature on test substrate surfaces during the application, spreading and drying steps of the in vitro method to measure ultraviolet (UV) transmission. The authors work in a range between 20°C and 35°C, and demonstrate that controlling temperature is a key test parameter that should be strictly controlled to ensure reliability.

Smart polymers can be engineered to contain reactive molecules, commonly dubbed “molecular switches,” that respond to external stimuli and cause systemic changes to the polymer structure. The specificity of a molecular switch to a single stimulus is critical for controlled release, although multi-triggered systems capable of responding to systematic stimuli are being developed for advanced applications. Herein the authors describe several stimuli-responsive materials that have potential applications for personal care and related biomedical fields.
