Evicide® anisate eco (INCI: Sodium Anisate) is the 100% natural, water-soluble sodium salt of p-anisic acid (Evicide Anise Eco). While it shares the same fungicidal power as its free-acid counterpart, its salt form provides a significant practical advantage for manufacturers. It is a targeted antifungal component designed for use within “multi-hurdle” preservation systems for natural and certified organic cosmetics.
Key Benefits and Performance
-
Superior Water Solubility: Unlike p-anisic acid powder, this salt form dissolves rapidly in water. This simplifies the manufacturing process and makes it the ideal choice for cold-process and high-speed production workflows.
-
Targeted Fungicidal Action: It provides robust protection against yeasts and moulds. It is a critical component for brands that want to avoid synthetic fungicides while maintaining product safety.
-
Multi-Hurdle Integration: It acts as the “fungal defense” in a broader preservation strategy. It must be paired with antibacterial agents (such as Sodium Levulinate) to achieve full broad-spectrum protection.
-
Gentle on Skin: Sodium Anisate is well-known for its excellent skin compatibility. It is frequently used in products designed for sensitive skin, baby care, and facial treatments.
Formulation Guidelines
-
pH-Dependent Activation: Because it is a salt, it must convert back into the active “undissociated” acid within the formula to work. For optimal performance, the final product pH must be below register to find out
-
pH Monitoring: At neutral or alkaline pH levels, its efficacy drops significantly. Always verify the final pH of your batch to ensure the antifungal protection is “switched on.”
-
Usage Level: Typically used at 0.1% – 0.3% as part of a synergistic preservative blend.
-
Applications: Perfect for natural toners, micellar waters, shampoos, and emulsions where ease of incorporation is a priority.
