Overview
Ichthammol (CAS 8029-68-3 ), also known as ammonium bituminosulfonate, is a sulfonated shale oil derivative used across pharmaceutical and personal care manufacturing. It functions primarily as an antimicrobial and anti-inflammatory active in topical formulations.
The drawing and preservative action of this compound drives its commercial demand. In pharmaceutical manufacturing, it is the active ingredient in drawing ointments and salves used to treat skin infections, boils, and folliculitis.
Personal care formulators incorporate it into medicated creams and scalp treatments targeting seborrheic conditions and chronic skin irritation. Veterinary product manufacturers use it in hoof care preparations and topical treatments for livestock.
Its antimicrobial action supports wound management in various animal species. Agricultural and feed-adjacent applications include use in animal husbandry topicals, where it functions as a biocide in formulations applied to working animals.
The product is supplied as a dark, viscous liquid or semi-solid paste, typically standardized to 10% or 20% active concentrations for pharmaceutical compounding. It is available in pharmaceutical-grade specifications.
The material meets BP and Ph.Eur. standards to ensure high purity for medical applications. Bulk supply is offered in drums or pails, with smaller quantities available for compounding pharmacies and specialty formulators.
