Spectrastat CHA (INCI: Caprylhydroxamic Acid, Caprylyl Glycol, Glycerin) is a versatile antimicrobial. Designed using advanced Hurdle Technology, this blend offers a broad-spectrum protection. By combining a unique organic chelating acid with a multifunctional glycol, it creates a collectively hostile environment for microbial growth without relying on traditional parabens, phenoxyethanol, or isothiazolinones.
Key Benefits and Performance
-
The “pH-Independent”Caprylhydroxamic Acid (CHA) in this blend remains undissociated at neutral pH. This allows for robust yeast and mould control even in formulations at higher pH
-
Triple-Hurdle Mechanism: * Chelation (CHA): A 100% natural organic acid that sequesters the iron (Fe3+) necessary for mould and yeast metabolism, effectively “starving” them.
-
Membrane Disruption (Caprylyl Glycol): A C8 diol that destabilizes the lipid membranes of both Gram-positive and Gram-negative bacteria.
-
Water Activity Reduction (Glycerin): Acts as a carrier that simultaneously lowers the “free water” available for microbial survival.
-
-
Broad-Spectrum Mastery: Proven efficacy against a full battery of challenge organisms, including Pseudomonas aeruginosa, Staphylococcus aureus, E. coli, Candida albicans, and Aspergillus brasiliensis.
-
Multifunctional Skin Benefits: Beyond its antimicrobial role, the blend functions as a skin-conditioning agent and humectant, contributing to a smooth, moisturized skin feel.
-
Cold Processable: A liquid blend that is easy to handle and can be incorporated without heating.
