| Product Number: | HE135 |
| size: | 500g |
| Ingredients: | Arctostayphlos Uva Ursi Leaf Extract. |
| Solubility: | Being a herb this ingredient will not fully dissolve in any solvent but instead should be steeped into a carrier and then filtered before using it in your product. Both the Arbutin and the Ursolic Acid are water souble so we recommend creating an extraction with water, water/glycerin or water/alcohol and then filtering it. The herb is a 5:1 extract which means it has been dehydrated so that 1 gram of dried herb contains as much active as 5g of fresh herb. You can make an extraction of any concentration you wish but we typically suggest using between 1-20% powdered herb into your solvent, steeping it to help extract the herb and then filtering. This would be equivalent to between 5-100% strength herbal liquid. The resulting liquid can then be dosed into your cosmetic at between 1-10% depending on the effect you desire. There is no guarantee that the extraction will liberate the chemistry you require although there are tests that can be done to check on the strength of the extracts but you could expect a theoretical concentration as follows |
