Good Vibrations: Spectroscopic Imaging to Visualize the Delivery of Actives
Most personal care formulas comprise a blend of water, emollients and stabilizing agents, but extracts and actives are also added for any number of benefits or claims. Ultimately, the efficacy of these products depends on the efficient transport of their actives to areas where they need to act. For example, emollients need to interact with the uppermost layers of the stratum corneum, but other actives should penetrate into the deeper layers of the skin.
The cosmetic industry has recourse in specialized delivery systems such as liposomes, liquid crystals and other self-organized systems that enhance the uptake of actives.
Understanding and visualizing how actives are delivered via these platforms is essential during product development and prior to final product commercialization to provide scientific data in support of a product’s efficacy. Read the full article in Cosmetics & Toiletries.
