Basic Green 1: An In-Depth Look at Its Role in Cosmetics

What is Basic Green 1?

Basic Green 1, also known by its chemical name [4-[4-(diethylamino)benzhydrylene]cyclohexa-2,5-dien-1-ylidene]diethylammonium hydrogen sulphate (CI 42040), is a synthetic dye primarily used in hair dyeing products. This vibrant green dye is part of the triarylmethane dye family, which is known for its bright and intense colors. It is also sometimes referred to as Malachite Green, although this term can be a bit misleading as it is not derived from the mineral malachite.

The history of Basic Green 1 dates back to the early 20th century when synthetic dyes began to revolutionize the textile and cosmetic industries. Initially developed for use in textiles, its vivid color and stability made it an attractive option for cosmetic applications, particularly in hair dyes. Over the years, its formulation has been refined to ensure safety and efficacy in personal care products.

The production of Basic Green 1 involves a complex chemical synthesis process. It starts with the reaction of benzaldehyde with diethylamine to form a Schiff base, which is then further reacted with cyclohexanone. This intermediate product undergoes a series of chemical reactions, including oxidation and sulfonation, to produce the final dye. The resulting compound is then purified and standardized to ensure consistent quality and performance in cosmetic formulations.
