Gentle, Natural Ingredients for Mousse Foam Makeup Remover

Creating a gentle mousse foam makeup remover for very sensitive skin requires careful selection of mild, natural-origin cleansing agents. While you mentioned wanting to avoid preservatives, it is highly recommended to include a gentle, broad-spectrum preservative system in any water-based product to prevent microbial growth and ensure safety, especially for sensitive skin. Omitting preservatives can lead to contamination that is far more irritating and harmful than a mild preservative.

For the cleansing base of your mousse foam, consider these gentle, natural-compatible surfactants:

• Sophorolipid (Natural Surfactant, 50%): This is a natural-origin surfactant produced by fermentation. It is known for being gentle on the skin while providing good foam and effective cleaning, including makeup removal. It can also help dissolve oils in water.
• Potassium Cocoyl Glycinate (90%, Solid) and Potassium Myristoyl Glutamate: These are highly gentle amino acid-based surfactants that provide good lather and are suitable for mild cleansing formulas.
• Sucrose Cocoate (Sugar + Coconut Surfactant): A natural surfactant derived from sugar and coconut oil. It is readily biodegradable and free of PEG compounds. It helps increase foam density and stability, provides a moisturizing effect, and improves skin feel during and after washing.
• Sodium Lauroyl Lactylate (Gentle Anionic Surfactant): Derived from natural and renewable resources (lactic and lauric acids), this surfactant is nitrogen-free and sulfate-free. It is very mild to the skin, helps with moisturization, and can act as a foam booster and stabilizer.

These ingredients can form the basis of a gentle mousse foam. For sensitive skin, it is also advisable to avoid adding fragrance, as requested.

Remember to research and select a suitable mild preservative system compatible with natural formulations to ensure the safety and longevity of your product.
