Product Information
Rosemary Extract Powder can be categorized into two main types based on its solubility: oil-soluble and water-soluble. The oil-soluble type is primarily standardized to carnosic acid and is widely valued for its strong antioxidant performance in lipid-based systems. The water-soluble type is mainly based on rosmarinic acid, offering versatile functionality for a broader range of formulations. With years of dedicated research and development, we are able to provide high-purity, high-content active ingredients tailored to meet diverse application needs.
Carnosic acid, a naturally occurring phenolic diterpene found in rosemary and related plants, is especially recognized for its excellent stability and compatibility with oils and fats. It performs effectively even under processing conditions, helping to maintain product quality, freshness, and stability. Thanks to its oil-soluble nature, it can be easily incorporated into oil-rich formulations across industries such as food, cosmetics, and other specialty applications, making it a reliable choice for modern formulations.
Lonierherb are committed to the continuous development of high-quality nutritional and functional ingredients, focusing on maximizing the value of natural resources. Through advanced processing techniques and strict quality management, we aim to enhance product performance, ensure consistent quality, and support innovation across multiple industries. Our goal is to provide dependable solutions that contribute to improved product quality and long-term sustainable development.
