Common Name(s): Camphanediol,camphanediol,bicyclic diol antimicrobial,camphor-derived preservation booster
CAS Number: N/a
DESCRIPTION
What It Does: Provides mild antimicrobial preservation boosting through the camphor bicyclic diol's membrane-partitioning activity, enabling reduced loading of primary preservatives in natural preservation systems.
Why It's Used: Camphor-derived diols provide antimicrobial activity with aromatic character from the terpene skeleton โ the bicyclic geometry creating a more effective membrane-interaction geometry than linear aliphatic diols for preservation boosting.
How It Works: Camphanediol's bridged bicyclic ring (bornane skeleton) positions the two hydroxyl groups in a constrained geometry that maximises membrane bilayer insertion versus flexible linear diols. the ring's conformational rigidity provides optimal amphiphilicity for microbial membrane disruption at low concentrations.
