I'm interested in sourcing a natural white colorant that can effectively serve as a substitute for titanium dioxide in our applications. It's important that the product meets our quality standards while also being cost-effective. Could you provide detailed information about the options available, including any relevant specifications and pricing? Additionally, I'm keen to understand any potential applications or limitations of the alternative colorant you recommend. Looking forward to your response!
