If stored properly, Botanical Extract will have a shelf life of 24 months.
Yes, the colors of the extracts can be pH-sensitive depending on the active. For example, in Bilberry Extracts, Anthocyanin is more stable at low pH (acidic conditions), which contributes a dark maroon to dark purple pigment. On the contrary, Anthocyanin at a higher pH value will cause the color to fade, with possible results ranging from blue to yellowish.
None of these extracts are bleached or processed harshly, which allows them to retain the natural colors and scents of the herbs from which they are derived.
Please be as specific as possible in describing your project and estimated which herbal extract will be used and we will check with our technical department and respond to you within 3 business days.
Botanical Extracts should be stored in cool, dry places away from moisture (e.g., humidity) and direct sunlight. The recommended long-term storage temperature is 20°C.
Whether Botanical Extracts are incorporated into pre-existing cosmetic bases or into products that are formulated from scratch, they can be added to creams, lotions, foaming products (for both skin and hair), anti-aging products, after-sun products, and rinse-off products. These extracts are water-soluble and can be combined directly with water without the use of heat, making them ideal for addition to cold process products. We recommend adding these extracts to final formulations when the temperatures are below 40°C, as this will ensure the effectiveness of the liquid extracts.
Botanical Extracts have excellent solubility in formulations and, because they are ready-to-use, they are extremely convenient.
A Standardized Botanical Extract is an herb extract that has a component or active present in a guaranteed specific amount, which is usually expressed as a percentage. The intention behind the standardization of herbs is to guarantee that the consumer is receiving a consistent product from batch to batch.
