Composition & description

Fatty oil obtained by supercritical CO2 extraction from raspberry seeds. This oil has a high content of polyunsaturated fatty acids: from 48 to 63% linoleic acid and from 23 to 30% alpha-linoleic acid, as well as tocopherols (vitamin E) and tocotrienols. It is an oil very rich in omega-3 and omega-6.

Properties

Oils rich in omega-3 and omega-6 are effective in the treatment of sensitive, dry, scaly and chapped skin.
These oils help to maintain hydration and strengthen the functioning of the skin membrane as well as the elasticity of the skin. They also act on atopic dermatitis and on skin impurities. They slow down hyperpigmentation and are generally used in regenerating cosmetic products. Raspberry CO2 extract also has a delicate raspberry seed fragrance.

Supercritical CO2 extraction

In this case, supercritical CO2 extraction is used to extract the oil from the raspberry seeds. Usually pressing is used to extract the oils from a plant, but when the oil content in the base material is less than 10%, pressing is inefficient and rarely recovers more than 50% of the existing oil, most of the oil remains in the cake and some of the interesting by-products such as phytosterols or miliacin cannot be fully exploited. In this case, two types of extraction are possible: extraction with supercritical CO2 or extraction with hexane. Hexane extraction (a hydrocarbon used as a solvent in organic chemistry) is the most common and most profitable, but the process is not very respectful of the organoleptic qualities of the raw materials. It requires a number of refining steps (degumming, decolourisation and deodorisation) in order to eliminate the residual solvents, which is associated with the loss or degradation of components. Hexane-extracted oils are generally not tolerated in natural cosmetics and cannot be certified as organic. None of the ingredients used by Floreleï use hexane extraction.

Supercritical CO2 extraction uses carbon dioxide (CO2) under pressure: a solvent that leaves no residue after use. Supercritical CO2 is therefore a modern - and very interesting - alternative to traditional organic solvents. The carbon dioxide used is natural, high-purity, volcanic and local, with a maximum pressure of 500 bar above the critical temperature of 31°C (88°F). This delicate process at room temperature allows the extraction of sensitive active ingredients, aromas and fragrances while respecting the raw materials.
