Skin-care industry skipping out on science
The multi-billion-dollar global cosmetics and skin-care-product industry sometimes is beset by a me-too mindset in which research and development focuses on matching the competition rather than applying sound science to improve products, according to chemist Stig E. Friberg. As a result, it could be missing a golden opportunity to provide consumers with more effective products, he said.
As an example, Friberg points out that previously unknown changes occur in the structures of colloids used in skin care lotions. As a result, the lotion sitting in the bottle, he said, is actually different from the same lotion applied to the skin.
Friberg has spent years in fundamental studies of the backbone of any lotion a mixture or emulsion of oil and water. Along with a third ingredient, a surfactant that keeps the liquids from separating, emulsions are the basis of almost every skin lotion. Although the system may sound simplistic, Friberg said its not as straightforward as scientists once believed.
Fribergs work has revealed that after application, evaporation causes a lotions internal structure to change, a fact that has not captured the attention of the skin-care industry. Initially in a liquid phase, the structure transforms while on the skin to a more orderly state, such as a liquid crystalline or solid amorphous phase, that allows for a higher
