Skin creams can be used for cosmetic purposes or to carry medically useful drugs. They contain a range of oils which often come from non-sustainable sources. For example, the squalene used in many creams has traditionally been obtained from animal sources such as sharks.

Uniqema have produced an oil, Pripure 3759, which is a colourless, odourless transparent liquid ideal for a wide range of skin care applications. It is derived from olive oil which means that the squalene it contains can now be obtained from a readily renewable raw material.

Vegetable squalane consists of three saturated terpene units. These are the natural building blocks of plant's essential oils and in a moisturising cream the Pripure helps to replace natural oils that may be lost from dry skin.
