I'm looking for a specific color additive to incorporate into my hair and body butter products. It's crucial that the color is vibrant and safe for both hair and skin applications. Could you provide recommendations on available options, including any relevant formulations or specifications? Additionally, please include information on the sourcing process, pricing, and lead times for the colorants. I'm interested in understanding the minimum order quantities as well. Your prompt response will help me move forward with my product development. Thank you!
