Our CO2 extracts can simply be added to oil-based or water-based products (though not purely water-based products as are they are oil-soluble and will not mix). Most (but not all) can be added without heating.
Because of their potency, they should only be used in a concentration of 1-2%. If you wish to combine two or more CO2 extracts in your product, make sure that their total concentration does not exceed 3% of the mixture. This is due to their strength and their synergising* effects. Each CO2 extract will also leave a trace colour in the product.
Some of our Botanical CO2 Extracts are solid at room temperature so have been mixed with Jojoba oil to make them easier to use. Some extracts are still prone to becoming more solid in colder temperatures. To resolve this, simply place the bottle of CO2 Extract into a mug or pan of warm-hot water for a few minutes until it is liquid.
