Delivery Systems and Ingredients on the Rise

Delivery systems and ingredients in personal care were valued at US $345,287.3 thousand in 2014, and this ingredient category is expected to grow to $543,373.2 thousand by 2020.

'Improved Antioxidant Penetration': Letter to the Editor

A recent Letter to the Editor calls to question some details in the logic presented in an April 2014 Cosmetics & Toiletries article.

Berg + Schmidt Launches Lecithin Fractions for Skin Compatibility

Berg & Schmidt has introduced a range of phosphatidylcholine (PC) fractions of lecithin from either soy or sunflower that can be used to manufacture liposomes, nanoemulsions, oleogels or formulations that are physiologically related to skin.

Charged Vesicles for Delivering Actives in Surfactant-based Formulations

The delivery of active ingredients in surfactants has long been a challenge due to the inability of such ingredients to stay affixed to the skin and hair after rinse-off. One solution is a delivery system that enables the encapsulation of actives in charged vesicles.

Characterization of Multilamellar Vesicles for Cleansing Applications

In the present article, the authors characterize a multilamellar vesicle (MLV) system used in personal care and verify its structure via X-ray scattering, rheology and fluorescence microscopy. This enabled the study of MLV formation to investigate bulk rheology characteristics. The results are presented here as application-relevant properties.

Microneedles: Just Deep Enough

Microneedle technology could, with supporting research, serve as a novel delivery system for personal care applications. Additionally, ingredients previously labeled as ineffective may find new life via this method, increasing the opportunity for skin care R&D.

A Delivery System for Treatment Bar Soaps

Many desired additives are not compatible with soap due to either the chemistry or the manufacturing process. Here, the authors describe an encapsulated delivery system incorporating polymers that survives the extrusion process and adheres to skin.

Delivering Actives via Solid Lipid Nanoparticles and Nanostructured Lipid Carriers: Part III, Stability and Efficacy

Part I of this review on Solid Lipid Nanoparticles (SLNs) and Nanostructured Lipid Carriers (NLCs) discussed the differences of these two delivery systems for cosmetic actives, as well as their production methods and selection criteria for constituents. In Part II, the characterization of these nano-sized particles was considered. In Part III, presented here, their stability and efficacy are considered; Part IV will address their application in cosmetics.

Berg + Schmidt Launches Lecithin Fractions for Skin Compatibility

Berg & Schmidt has introduced a range of phosphatidylcholine (PC) fractions of lecithin from either soy or sunflower that can be used to manufacture liposomes, nanoemulsions, oleogels or formulations that are physiologically related to skin.

Review of Pseudopeptidic Compounds for Biocompatible Gels

Simple pseudopeptides derived from natural amino acids can be designed and prepared as efficient gelators for a variety of solvents, and with a high potential for biocompatibility. The appropriate selection of structural components, reviewed herein, shows how to produce gels with tailored properties, including high thermal stability.

Delivering Actives via Solid Lipid Nanoparticles and Nanostructured Lipid Carriers: Part IV, Absorption and Formulations

In this fourth part of a five-part series discusses the percutaneous absorption of actives loaded into solid lipid SLNs and NLCs and their formulation in dermal cosmetics.

Swellable, Nanoporous Organosilica for Extended and Triggered Release

Nanoporous organosilica particles were developed to swell upon the addition of organic solvents. These are evaluated here for encapsulating and controlling the release of fragrance. Slower, continuous release was observed, suggesting their ability to extend sensory benefits. In addition, the stimulated release of encapsulated lidocaine was studied, and results implicate their use to deliver cosmetic actives.
