Synthesis of Lexgard Natural MB:
Lexgard Natural MB is synthesized through a controlled process in which naturally derived multifunctional ingredients—typically including nature-identical antimicrobial actives, organic acid derivatives, and mild humectant-type compounds—are combined under regulated temperature, pH, and mixing conditions to produce a uniform, liquid preservation-boosting system.
The synthesis begins with the purification and preparation of bio-based raw materials, which are then reacted or blended in precise ratios to achieve the desired antimicrobial potentiation and multifunctional performance profile.

Key components are esterified, neutralized, or selectively condensed depending on their chemical nature, allowing the formation of stable antimicrobial structures that exhibit broad compatibility with cosmetic formulations.
Throughout the process, moisture content, impurity levels, and thermal conditions are tightly controlled to preserve the integrity of the natural-derived molecules and to avoid undesirable by-products.

The mixture is then homogenized and polished filtered to ensure clarity, low odor, and consistent viscosity.
The resulting product is a fully blended, ready-to-use natural preservation booster with optimized solubility, enhanced antimicrobial synergy, and reliable stability in both emulsified and anhydrous personal care systems.
