The Damiana Powder Extract 10:1 (INCI: Turnera Diffusa) is a concentrated botanical raw material derived from the whole plant. As a golden-yellow to light-brown powder with an extraction ratio of 10:1, it is aimed at formulators and product developers in the cosmetic and food industries who are looking for a flavonoid-containing plant extract in a stable, easily dosable powder form. For processing, an extract of ethanol and water as well as maltodextrin as a carrier are available.
Turnera diffusa as the botanical basis
Damiana (Turnera diffusa) is an aromatic shrub. For this extract, the whole plant (Whole Plant) is processed, which incorporates the broad phytochemical profile of the species into the concentrate. The starting material originates from China and is processed into a fine powder with a particle size of 80 mesh (minimum 95 percent through 80 mesh, untamped).
Flavonoids as lead markers
Analytically defining for the Damiana Powder Extract are flavonoids, in particular apigenin and acacetin. In the product, flavonoids are indicatively present at 7 to 45 mg/g, derived from 0.1 to 0.5 percent in the dried plant material, multiplied by the concentration factor 10:1 and a yield of 70 to 90 percent. Apigenin is documented in the starting material at 0.05 to 0.2 percent.
As further verified compounds, essential oil containing cineol (0.5 to 1 percent in the starting material) as well as arbutin as an analytically accessible marker are documented. No quantitative figure is available for arbutin.
Cosmetic activity profile according to CDS
For cosmetic application, the Damiana extract is classified as soothing, based on the phytochemical profile and published literature. The cosmetic targets documented include ROS scavenging, MMP inhibition and modulation of NF-kappaB. These details describe the activity profile stored in the CDS and serve as guidance for formulation development; they do not constitute a formulation recommendation.
The extract is suitable for all cosmetic variants and is eligible as a cosmetic raw material in accordance with Regulation (EC) No. 1223/2009. The CDS recommends a use level of 1 to 3 percent for cosmetics; the general product recommendation is 2 to 5 percent. At a use level of 2 percent, a calculated 0.14 to 0.90 mg/g of flavonoids is introduced into the formulation.
Use in functional foods
For the food sector, the Damiana Powder Extract is classified as a nutritional antioxidant and as a traditional dietary ingredient. The targets listed in the CDS include metabolic health and oxidative stress reduction. A use level of 0.5 to 2 percent is recommended in functional foods and beverages; at a use level of 1.3 percent, a calculated 0.09 to 0.56 mg/g of flavonoids results in the formulation. The product is suitable for all carrier variants in food applications and is vegan.
Processing, stability and documentation
The Damiana Powder Extract is a brown powder with a characteristic odour and taste and a density of 0.50 to 0.70. When stored dry between 10 and 30 degrees Celsius in the original sealed container, the shelf life is 24 months. A temperature- and storage-dependent change in colour cannot be excluded. According to the SDS, the powder is not a hazardous substance in accordance with Regulation (EC) No. 1272/2008 and is not a dangerous good for transport; vapours and aerosols should not be inhaled. We provide the complete data via our technical documentation (TDS/SDS/CDS).
