Abstract: A Swertia chirata extract obtained by extracting with supercritical CO2 an alcoholic extract of Swertia chirata, and to a cosmetic composition including such an extract having in particular an anti-ageing effect for the skin. Also, administering such an extract in a cosmetic method for preventing and/or reducing skin ageing and a cosmetic method for hydrating the skin and/or improving the barrier function of the skin.

Abstract: An alcoholic extract of Citrus depressa peels, a cosmetic composition including such an extract having in particular a preventive effect against desquamation of the skin, as well as its method of preparation. Also, the method of limiting/protecting against excessive desquamation and contributing to skin comfort by applying the alcoholic extract of Citrus depressa peels to the skin.

Abstract: An oil extract from Gardenia jasminoides flowers obtained by extraction from powder of Gardenia jasminoides flowers with supercritical CO2, and the process of obtaining such an extract. Also, cosmetic composition including such an oil extract from Gardenia jasminoides flowers having in particular an antiaging effect for the skin, and method for preventing and/or treating changes to the skin due to aging or photoaging using such an extract.

Abstract: A process for the microfluidic extraction of molecules of interest from a vegetable oil, which utilizes a microfluidic chip with a double-Y-channel circuit, two inlets, two outlets, and a main channel, a first vessel including vegetable oil and a second vessel including ethanol for extraction, a pressure controller for pressurizing the vegetable oil and the ethanol, a first collector for the triglycerides-enriched vegetable oil and a second collector for molecules of interest-enriched ethanol. The extraction process includes: controlling the pressures to subject each of the vegetable oil and the ethanol to a pressure, so the interface between the two fluids is positioned at the junction point of inlets, bringing the vegetable oil and ethanol into contact with each other in the main channel for a time to enable extraction of the molecules of interest, collecting the molecules of interest-enriched ethanol, optionally, evaporating the ethanol, collecting the triglycerides-enriched vegetable oil.
