Lexgard® Natural MB is an all-natural multi-functional ingredient system for self-preserving cosmetics. Lexgard® Natural MB is composed of high purity monoesters of caprylic acid (C8 acid) and undecylenic acid (C11 acid). The former is well established for its biostatic activity against bacteria and yeast. The latter is known for its activity against fungus. Formulations with Lexgard® Natural MB efficiently pass challenge tests required in the cosmetics industry. Lexgard® Natural MB is an emollient, co-emulsifier, skin re-fatting agent, and biostatic system. It is especially recommended for use in w/o or o/w emulsion systems such as skin care creams and lotions. It should be incorporated in the water phase during cool down or during the emulsification process. For antimicrobial performance, a dosage of 1.0% – 1.5% is recommended. Lexgard® Natural MB is stable and effective at pH 4.0 – 8.0, with optimal results at pH 5.5 or lower.
