Lac dye is a natural colorant derived from the secretions of the lac insect, primarily found in parts of India and Thailand. The dye is extracted from the resinous material that the insects produce while feeding on tree sap. It has been used for centuries in textiles, cosmetics, and art due to its vibrant red and purple hues. This dye is considered eco-friendly and biodegradable, making it a popular choice for those seeking sustainable alternatives to synthetic dyes. Lac dye is often used in traditional crafts, such as handloom textiles and natural dyeing processes, highlighting its cultural significance and versatility.
