Journal Article
Binks, B. P., Fletcher, P. D., Johnson, A. J., Marinopoulos, I., Crowther, J. M., & Thompson, M. A. (2017). Spectrophotometry of thin films of light absorbing particles. Langmuir : the ACS journal of surfaces and colloids, 33(15), 3720-3730. doi:10.1021/acs.langmuir.6b04443

Thin films of dispersions of light absorbing solid particles or emulsions containing a light absorbing solute all have a non-uniform distribution of light absorbing species throughout the sample volume. This results in non-uniform light absorption ov... Read More

How the sun protection factor (SPF) of sunscreen films change during solar irradiation (2016)
Journal Article
Binks, B. P., Fletcher, P. D., Johnson, A. J., Marinopoulos, I., Crowther, J., & Thompson, M. A. (2017). How the sun protection factor (SPF) of sunscreen films change during solar irradiation. Journal of Photochemistry and Photobiology A: Chemistry, 333, 186-199. doi:10.1016/j.jphotochem.2016.10.027

We have investigated how the sun protection factor (SPF) of different types of sunscreen film varies with “standard” solar irradiation due to photochemical processes. We have used a combination of chemical actinometry, measurement and modelling to es... Read More

Evaporation of particle-stabilised emulsion sunscreen films (2016)
Journal Article
Fletcher, P. D., Binks, B. P., Johnson, A. J., Marinopoulos, I., Crowther, J. M., & Thompson, M. A. (2016). Evaporation of particle-stabilised emulsion sunscreen films. ACS applied materials & interfaces, 8(33), (21201-21213). doi:10.1021/acsami.6b06310. ISSN 1944-8244

We recently showed (Binks et al., ACS Appl. Mater. Interfaces, 2016, DOI: 10.1021/acsami.6b02696) how evaporation of sunscreen films consisting of solutions of molecular UV filters leads to loss of UV light absorption and derived sun protection facto... Read More

Evaporation of Sunscreen Films: How the UV Protection Properties Change (2016)
Journal Article
Fletcher, P. D., Fletcher, P. D. I., Binks, B. P., Johnson, A. J., Marinopoulos, I., Brown, J., …Thompson, M. A. (2016). Evaporation of Sunscreen Films: How the UV Protection Properties Change. ACS applied materials & interfaces, 8(21), (13270-13281). doi:10.1021/acsami.6b02696. ISSN 1944-8244

© 2016 American Chemical Society. We have investigated the evaporation of thin sunscreen films and how the light absorption and the derived sun protection factor (SPF) change. For films consisting of solutions of common UV filters in propylene glycol... Read More
