Rosemary Extract as an Industrial Antioxidant for Oils, Cosmetics and Feed
Rosemary extract powder in a 1 kg pack is designed for manufacturers who need a reliable volume of raw material for regular production runs. It is a concentrated powder derived from the plant leaves, valued mainly for its high content of natural antioxidants such as carnosic acid, carnosol and rosmarinic acid. This product belongs to the category Powdered Extracts and Algae, which gathers plant concentrates for various processing industries.
The largest global demand for rosemary extract comes from the food industry, where it serves as a natural alternative to synthetic antioxidants for stabilizing vegetable and animal fats, processed meats, sauces and snacks, extending shelf life without oxidative rancidity. Another major segment is animal feed production, where the extract is added to compound feeds and premixes to protect fats from oxidation during storage. In cosmetics it is used in creams, shampoos, serums and body care products as an ingredient that slows down oil oxidation within the formula and keeps the finished product fresh, while in household chemicals and perfumery it works as an additive to oil-based compositions.
For industrial formulations, the typical dosage ranges from 0.05 to 0.3 percent of the fat phase weight, depending on the type of oil and the required shelf life. The powder should be introduced during the mixing stage with oils or fats at a temperature not exceeding 60-70 degrees to preserve the activity of the active compounds. Rosemary extract combines well with other plant concentrates and antioxidants, allowing manufacturers to build complex formulations with an enhanced protective effect.
For testing a formulation on a small scale before launching a large production batch, it is convenient to use Rosemary Extract Powder 5 g, which allows checking the dosage without risking the main purchase. In complex antioxidant and skin care compositions, rosemary is often paired with rosehip extract, known for its high vitamin C content and ability to support skin tone - try Rosehip Extract Powder 5 g. For formulations with exfoliating and brightening action, such as facial creams or peels, rosemary can be combined with Papaya Extract Powder 10% 10 g, which contains enzymes that support skin renewal.
The extract should be stored in an airtight package, in a dry place away from direct sunlight, at room temperature, avoiding contact with moisture so the powder keeps its activity throughout its shelf life. The 1 kg pack suits conveyor-line manufacturing and allows planning purchases over a longer period without frequent reorders, which is convenient for food processing plants, feed manufacturers and mid-to-large cosmetic laboratories.
