Lexgard GMCY MB

Lexgard® GMCY MB (INCI: Glyceryl Caprylate) is a 100% natural, readily biodegradable multifunctional preservation component derived from coconut and palm feedstocks. As a high-purity monoester (minimum 85% monoester content), it is specifically designed as a primary building block for “Hurdle Technology” in natural and clean beauty. 

Key Benefits and Performance

• Bacteriostatic Control: Creates a hostile biostatic environment that primarily inhibits the growth of Gram-positive and Gram-negative bacteria.

• Membrane Disruption: Its lipophilic nature allows it to interact with and destabilize microbial cell membranes, enhancing the efficacy of other antimicrobial agents in the system.

• Skin Conditioning & Humectancy: Functions as a versatile emollient and moisturizer, improving skin feel and helping to maintain the skin’s moisture balance.

• Wetting & Surface Activity: Acts as a natural wetting agent, assisting in the dispersion of pigments or other insoluble components in complex formulations.

• High Purity: The controlled 85% monoester content ensures consistent performance and predictable stability across different production batches.

Formulation Guidelines

• Preservation Strategy: While potent against bacteria, it has limited efficacy against yeast and mould. It must be paired with a dedicated antifungal agent (such as Caprylhydroxamic Acid) for a complete broad-spectrum system.

• Clarity in Formulations: In clear aqueous systems (e.g., micellar waters or clear gels), a solubiliser is recommended to prevent turbidity, as Glyceryl Caprylate is lipophilic.

• Application Range: Highly effective in emulsions (creams/lotions) and surfactant-based systems (shampoos, facial cleansers, shower gels).

• pH Stability: Best used in the slightly acidic range typical of skin care. Extreme pH levels may lead to hydrolysis of the ester bond over time.
