Novel Azobenzene Compound to Extend and Reactivate UV Protection

Two azobenzene compounds were synthesized and combined in liposomal membranes. Their physico-chemical properties and biocompatibility were evaluated. The safer one was chosen, and its protective function for UVA and UVB were tested in vitro and in vivo. This azobenzene liposomal formulation provided good efficacy with longer shelf life, which could be utilized as a novel kind of repeated UV absorber.

Ashland Adds Homosalate UVB Filter to Offering

Ashland Specialty Ingredients, a commercial unit of Ashland Inc., has added a homosalate UVB filter to its Escalol range of UV filters.

UVA Skin Protection: Issues and New Developments

Photoinduced degradation and activity in chemical and mineral UV-absorbing actives results in a decrease in UVA protection during topical use, with a corresponding risk of skin pathologies in the user. New developments in UV absorbers are shown to maintain a stable, high level of UVA protection during use.

CSIRO and Larissa Bright Mimic Coral Protection for Broad-spectrum UV Filters

CSIRO, in partnership with skin care company Larissa Bright Australia, has created UVA/UVB sunscreen filters that mimic the natural sun protection used by corals on the Great Barrier Reef.

Sensational Sun Care with Protection and Sensory

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.

A Sunscreen Formulation for Acne-prone Skin

This article describes the study of a topical sunscreen formulation that contains titanium dioxide and ethylhexyl methoxycinnamate for UV protection, and phosphatidylcholine and hydrosoluble azelaic acid for acne control.

Research Pathways to Photostable Sunscreens

This article provides a visual depiction of pathways that UV filters undergo when exposed to solar radiation; such pathways often lead to photo-instability. A fluorescence technique is described that has led the author to identify compounds that preserve photostability in a novel manner­— by quenching the UV filter’s singlet excited state.

Chitin Nanofibrils for Improved Photoprotection

Chitin nanofibrils (CN) are capable of interacting with cosmetic actives by binding to the stratum corneum, thus influencing their thermodynamic activity. Here, the authors test various sunscreen samples and determine that the addition of CN provides an interesting boost to the photoprotective activity of sunscreens.
