This article reviews in vitro studies that have found Chinese licorice extract to impart potent antibacterial and soothing properties, which make it an interesting candidate for applications in oral and personal care. Further, a clinical study is described in brief, assessing the ability of a supercritical CO2 extract from Chinese licorice to impart breath-freshening properties.

In recent years, the safety of traditional preservatives has been called into question. Therefore, there is a need for alternatives that are effective, safe and sustainable—and that are non-controversial. In response, the present work investigates a mixture of caprylyl glycol and phenethyl alcohol, which is shown to provide antimicrobial activity in various skin and hair care formulations.

Demands for innovation and nature in personal care products have, until now, experienced parallel growth according to consumer perception; i.e., the need for efficacy and the need for purity. Considering these diverse views, this article explores how it is possible to create products that satisfy both via sustainability; bringing natural sourcing to ingredients that are innovative and scientifically proven.

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.

Preservatives are critical ingredients in personal care products and cosmetics, where they help to ensure consumer safety as well as product performance and stability. Among these materials, formaldehyde-donor (FD) preservatives have demonstrated a long history of safe and effective use for controlling microbial growth.

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.
