Dolichos biflorus cell culture extract is evaluated here for its effects on skin cells. Results indicate the extract provides strong anti-inflammatory, antioxidant and protective properties for skin, and the ability to repair UV-induced damage. Further, this work reinforces that cell culture systems are efficient biofactories to produce natural and effective compounds.
There will always be room for improvement in the sun care industry, which continues to innovate worldwide with better UV filters, measurement techniques and finished formulations. This was reflected at the Florida chapter of the Society of Cosmetic Chemists' 2013 Sunscreen Symposium, which was held Sept. 18-21, 2013, in sunny Orlando, Florida.
Ashland Specialty Ingredients, a commercial unit of Ashland Inc., has added a homosalate UVB filter to its Escalol range of UV filters.
Up until now, the sunscreen industry had not been able to deliver the advanced feel that consumers were seeking in their formulations, especially those containing inorganic sunscreen filters. To answer this need, Croda has developed an inorganic sunscreen filter with truly sensational skin feel.
In its comments, PASS requests the CDC to "urge the FDA to clear the 10-year backlog in new sunscreen applications and create a predictable, transparent and timely review process for pre-market approval of new sunscreen ingredients."
Patent Picks are taken from publicly available sources and cover recent patents issued or applied for in the cosmetic and personal care industries and relevant peripheral markets. This edition features sun protection and skin repair technologies.
If like me, you’re just daydreaming of the beach, this collection of articles will enlighten you with its focus on sun protection, SPF testing, damage repair and more.
This work evaluates the impact of three different substrates on in vitro SPF measurements, and defines experimental conditions to improve their correlation with in vivo values. Evaluations of 32 products, shown here, led the authors to conclude that molded substrates improved repeatability and correlation with in vivo SPF values.
Lab tests on sunscreens show it takes more energy to produce mild erythema on protected skin than unprotected skin. Yet the FDA questions the need for SPFs higher than 50. In response, two outdoor studies were conducted using commercial products to challenge standing premises and determine if there is a measurable difference in an SPF 100 and SPFs of 50 or less.
There are various test methods set by global governing bodies for SPF protection, but this article will discuss the five time-point internationally approved ISO 24444 method.
