About this product

Inci: Helianthus Annuus Seed Oil, Aesculus Hippocastanum Seed, Rosmarinus Officinalis Leaf Extract

A relatively unknown oil that is great for evening out the complexion. Also used in sports products.

PRODUCT DESCRIPTION

A pale yellow liquid with characteristic aroma is made from the seeds of the Aesculus Hippocastanum tree, which is colloquially known as the Horse Chestnut. The seeds are often called conkers. The organic Horse Chestnuts are macerated in warm (35 ̊C) organic High Oleic Sunflower Oil which is then filtered and 0.1% rosemary antioxidant is added to prevent oxidation of the oil.

The ratio is 37.1% dry horse chestnuts to 62.9% oil by weight, then 0.1% rosemary antioxidant extract added by weight. As this is a natural product, you may find sediment at the bottom of the bottle. Filter it out should it occur.

Use 4% to 30%.

Oil soluble so cannot be used in water only products. It can be used in small amounts in water based gels that will hold it in suspension.

Heat stable so can be used in Stage 1 (fat stage) when making creams and lotions.
