Sunflower lecithin is a natural emulsifier derived from sunflower seeds. It is commonly used in food and cosmetic products as an alternative to soy lecithin. Lecithin is a fatty substance that helps to stabilize and blend ingredients that would otherwise separate, such as oil and water. Sunflower lecithin is often used in baking, chocolate production, and as an ingredient in various processed foods. It is considered safe for consumption and is generally well-tolerated by most individuals.
