The combination of Caprylhydroxamic Acid, Glyceryl Caprylate, and Glycerin forms a multifunctional preservation system used in Spectrastat™ G2 Natural MB, a 100% naturally derived, broad-spectrum preservation solution designed for self-preserving cosmetic formulations. The blend uses a hurdle technology approach, where each component contributes complementary antimicrobial and formulation-supporting properties to inhibit microbial growth. Caprylhydroxamic Acid functions as the primary antimicrobial agent, helping control bacteria, yeast, and mold through metal-chelating activity that interferes with microbial metabolism. Glyceryl Caprylate enhances antimicrobial efficacy while also providing mild emollient and skin-conditioning properties that support overall formulation performance. Glycerin acts as a humectant and carrier, improving moisture retention and helping stabilize the ingredient system within aqueous formulations.

The combined activity at recommended use levels of approximately 1.5–2% of these ingredients provides effective preservation across a broad pH range, typically between pH 4 and 8, allowing formulators to create products that maintain microbial integrity without the use of traditional preservatives such as parabens, formaldehyde donors, MIT, or phenoxyethanol. Due to its multifunctional nature and natural origin, Spectrastat™ is suitable for a wide variety of cosmetic applications, including emulsions, cleansing systems, wipes, lotions, and color cosmetics.

In hair care formulations, this preservation system supports microbial protection while maintaining a mild sensory profile compatible with modern natural or clean-label products. Its compatibility with surfactant systems and emulsions makes it particularly suitable for shampoos, conditioners, and scalp treatments where effective preservation and formulation stability are essential for product safety and shelf life.
