CAS No.: 84604-20-6

Active substances:

Polyunsaturated fatty acids, mainly linoleic acid in form of acylglyceroles; phytosterols (β - sitosterol,  -7-stigmasterol, stigmasterol, campesterol); phospholipids, phytosqualene.

Properties:

Milk thistle oil exhibit extremely favorable properties regarding skin reparation and renewal due to high content of linoleic acid. Present phospholipids enhance penetration of active principles into deep layer of the skin and phytosterols are responsible for the appropriate water retention in skin in so far that it remains fully hydrated and nourished. Oil can be easily incorporated into final cosmetic preparation thanks to low tension on the boundary of water and lipid phases (polar oil).

Oil obtained during pressing of Milk thistle seed does contain all the oily components of the seed in their natural proportion and quality. The only processing is the cold filtration of this oil through inert filtration plate to avoid small mechanical impurities originated at the pressing from the solid part of the seed. This so called virgin oil is of deep yellow colour with characteristic plant smell and oily taste.

Regarding the categorization, Milk thistle oil belongs to the group of drying oils because of high content of polyunsaturated fatty acids which readily polymerize finally creating a sticky mass. The total composition of fatty acids in Milk thistle oil is very convenient with respect to proportion between unsaturated and saturated acids.
