Incorporating performance ingredients in a formula does not guarantee they will penetrate the skin and deliver the claimed benefits. This review presents topical delivery approaches introduced in the past five years to improve the efficacy of benefit ingredients for skin care. Examples include molecular, carrier and Trojan horse delivery. Non-conventional delivery systems also are described.

The effective preservation of personal care products and cosmetics is vitally important to inhibit microbial growth. Phenoxyethanol has a long history as an effective preservative, with well-documented human and environmental safety profiles. This is a valuable option in formulators’ and microbiologists’ toolboxes for safe and effective control of microbial growth, as is reviewed here.

To protect enamel, new mechanisms in classic oral care continue to be uncovered, while modern advances mimic and enhance natural protective systems. New approaches to enamel repair include augmenting natural remineralization by creating reservoirs of ions and applying saliva biomimetics. Such technologies, described here, represent significant advances for repairing and protecting teeth noninvasively.
