Rosemary Leaf Extract

The leaves of Rosmarinus officinalis are used to create Rosemary Leaf Extract by controlled solvent extraction and concentration methods, prepared for the industry. Carusen is rich in naturally occurring antioxidants carnosic acid and carnosol, which give many formulations better stability against oxidation. Since it is made for B2B use, this extract is common in the processing of packaged foods, nutritional formulas, toiletries, and additives that require consistent quality, extend shelf life, and must have easy-to-understand labels. This extract has enough effect, withstands temperature, and can be used in many formulations, which is useful for large-scale production in sensitive systems where oxide and environmental depletion is a problem. The fact that it matches global quality guidelines and that people now prefer plant-based over synthetic preservation makes it a safe and effective choice when companies are sourcing natural ingredients.

B2B manufacturers in the food, nutraceutical, and cosmetic industries can use our Rosmarinus Officinalis Extract, which is available in various standardized options to match different formulation needs. The different Carnosic Acid amounts we supply vary from 5% to 60%, and this main active component is appreciated for its powerful antioxidant properties. Our product can be adjusted to have varying amounts of Rosmarinic Acid (3%–20%), Ursolic Acid (25%–95%), and Polyphenols (10%–50%), depending on what it's needed for. Every batch is produced using high standards to guarantee stability, consistency, and compliance with rules in the industry, supporting customers who use such ingredients in their clean-label and added-value items.

1. High Active Compound Flexibility

We provide many different specifications for carnosic acid, rosmarinic acid, ursolic acid, and polyphenols so that customers can find the exact fit for their product.

2. Excellent Batch Consistency

Because we standardize our sourcing and use controlled extraction, the color, solution, and active parts of the final product remain uniform, which is required for big-scale and multi-batch production.

3. Versatile Compatibility

Since the extract can be added to any type of system, it is just right for making food emulsions, cosmetic bases, and dry powder mixtures.

4. Superior Thermal and Oxidative Stability

During high-temperature processing, the key nutrients still act as antioxidants and can provide security in baked, fried, or pasteurized goods.

5. Following the Rules Globally

Because the product is made according to GMP standards, full documentation (COA, MSDS, and technical data) supports its use along export and B2B supply routes.

6. Clean-Label Friendly

Because it's 100% natural and has no additives, it supports the clean label trend, which helps brands succeed in markets concerned about ingredients.

The precise version of Rosemary Extract should be picked according to what you are making, how it will be processed, and what its purpose is. In cases where strong lipid protection is important, such as with high-fat foods or oil-based nutrition, foods can be fortified with carnosic acid at levels of 40%–60% to enhance its value as an antioxidant. To boost antioxidant capacity in beverages, sauces, or personal care products, it's better to look at rosmarinic acid content (such as 10%–20 %). Those looking for a specification with many properties, such as antioxidant, emulsifying, and anti-aging, in cosmetics or nutraceuticals should seek compounds with high ursolic acid (at least 70%) or polyphenol (at least 30%) levels. It helps to check the physical state of the nutrients-if they are powders or extracted oils-to guarantee the smoothness and compatibility of the food itself. Your formulation goals, the necessary regulations, and the place you want in the market should influence your final specification.
