Patent Pick: Reloadable Microcapsules Answer Fragrance Formulating Challenge

Just when you thought your formula was optimized, you tried to add fragrance. And what happened? You lost it in the aqueous phase. How can you control this partitioning and release? A new patent application from IFF may have your answer.

Patent Pick: Super Absorbent Matrix Extends Fragrance Release

Inventors at fashion and fragrance company PUIG have delayed the inevitable—in a good and cross-linked way. A new European patent application explains.

Eco-friendly Microparticles Carry Delivery Promise

Interest in cosmetic actives continues to grow, and delivery systems—especially eco-friendly ones—are a next logical market sector to follow. The timing might be right for findings in delivery such as those reported here, from the labs of Pierre Fabre and Université Paul Sabatier.

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.

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.

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.

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.
