Caprylyl Glycol: A Versatile Material to Boost Preservatives
Jul 1, 2018 | Jon Toliver and Saroja Narasimhan, Ph.D., Johnson & Johnson Skillman, NJ USA
As consumers become more decidedly "anti-preservative," formulators are faced with the need for versatile preservation systems. Caprylyl glycol's flexible nature allows it to be incorporated into a variety of formats while serving consumer needs.
A New Spin on Delivery: Electrospun Collagen Drives Actives to New Depths
Jun 28, 2018 | Bhuvana Kannan, Ph.D., Pablo Lepe, Ph.D., and Iain C. Hosie, Revolution Fibres Ltd., New Zealand
Nanofibers from marine collagen were tested for their ability to deliver hyaluronic acid and grapeseed and kiwifruit bioactives into skin. Results showed they penetrated in under one minute. This sustainable and natural platform removes the need for emulsifiers, penetration enhancers and other transporter ingredients. It also enables the encapsulation of a wide range of water- and oil-based actives.
Comparatively Speaking: PPG vs. PEG
Jun 1, 2018 | Anthony J. O'Lenick, Jr.
The chemistry of PEG, PPG or combinations thereof have an impact on the functional properties of formulas. Knowledge of these materials will help the chemist understand both the effects of reacting these materials on fatty alcohols as well as the performance of emulsifiers and wetting agents.
Binding Force: Natural Oxidized Keratin Internalizes Hair Repair
Jun 1, 2018 | A.D. Roddick-Lanzilotta, Ph.D., R.J. Kelly, Ph.D., G.H. Worth, Ph.D., and P.R. Sapsford, Ph.D., Keraplast Manufacturing Ltd., Canterbury, New Zealand
Bond multipliers have been developed to protect and repair hair. One in particular is a novel natural keratin alternative. Here, it is shown to retain fiber flexibility and protect and repair hair by binding intermediate filament proteins within the fiber.
