Bithional is considered a prohibited cosmetic ingredient primarily due to its safety concerns and potential health risks. Originally used as an antimicrobial agent, studies have shown that it can cause skin irritation and has been linked to potential toxicity. Regulatory bodies have evaluated the safety profiles of various cosmetic ingredients and have determined that certain substances, such as bithional, should not be included in cosmetic formulations to protect consumer health.

On the other hand, hydroxybenzoate (more commonly known as parabens) and acetone are widely used in cosmetics, subject to specific regulations regarding concentrations and usage to ensure safety. Silicone derivatives are also prevalent in cosmetic formulations, offering benefits like smoothness and moisture retention without the same safety concerns associated with bithional. The prohibition of specific ingredients like bithional is grounded in the necessity of ensuring consumer safety while maintaining the efficacy and quality of cosmetic products.
