Overview
Totarol (CAS 511-15-9 ) is a naturally derived diterpenoid phenol extracted primarily from the heartwood of Podocarpus totara. It functions as a potent antimicrobial and antioxidant active.
This compound is used in preservation systems and bioactive formulations across personal care and pharmaceutical development. In cosmetic formulations, it is incorporated as a natural preservative booster.
It is effective against gram-positive bacteria and offers an alternative to synthetic biocides in clean-label product lines. Skincare brands use it in creams, serums, and deodorant formulations.
It is ideal where broad-spectrum antimicrobial activity is required alongside antioxidant protection. Pharmaceutical researchers apply it in topical and oral care preparations targeting bacterial biofilm disruption.
It is particularly useful in anti-acne and anti-plaque product development. Its antioxidant capacity also supports stability in lipid-rich formulations, helping extend shelf life in oil-based personal care products.
The product is typically supplied as a fine powder or resinous solid, with purity grades commonly ranging from 95% upward for cosmetic and research applications. Standardized botanical extracts are also available.
These extracts contain defined concentrations for formulators seeking a diluted, easier-to-handle format. Buyers should confirm specification documentation, including HPLC-verified purity and botanical sourcing details.
This is essential when evaluating suppliers for regulated end-use applications. Quality control ensures the material meets the rigorous demands of the global chemical and pharmaceutical industries.
