Preservatives for Lipstick and Lip Gloss

For lipstick and lip gloss formulations, which are typically oil, wax, and butter-based, it is recommended to use a preservative that can disperse well in oil phases.

Based on the properties, products like Mild Preserved Eco, Mild Preserved SC10, and Mild Preserved CGZ are suitable options. These ingredients are designed to disperse in oil-based formulas, making them effective for lip products.

The recommended usage rate for general cosmetic formulas, including lipstick and lip gloss, is typically 1.0-1.5%. Using 1% is a good starting point as suggested.

These ingredients are also noted as not being classified as preservatives under FDA regulations, allowing products using them to potentially be labeled as "preservative-free".

Always perform a challenge test on your final formulation to ensure the chosen preservative system is effective.
