Understanding the fundamental chemical profile of an ingredient is crucial for formulators and procurement specialists. Ammonium Sulfobituminate, also known as Ichthammol, is a unique compound with a rich history and diverse applications. From a manufacturer's perspective, ensuring the consistent quality and precise chemical characteristics of this substance is our top priority. This article delves into the chemical aspects of Ammonium Sulfobituminate (CAS 8029-68-3) and its importance in various industrial sectors.

Chemical Composition and Structure

Ammonium Sulfobituminate is not a single, pure chemical compound but rather a complex mixture derived from the sulfonation of sulfonated shale oil, followed by neutralization with ammonia. While its exact composition can vary, it is primarily composed of:

  • Sulfonated Hydrocarbons: These organic compounds, bearing sulfonic acid groups (-SO3H) attached to hydrocarbon chains, form the backbone of Ichthammol.
  • Ammonium Salts: The neutralization process results in ammonium salts of these sulfonated organic compounds, contributing to its solubility and chemical reactivity.
  • Organically Bound Sulfur: A significant portion of its therapeutic efficacy is attributed to the high percentage of organically bound sulfur, which is believed to be responsible for its anti-inflammatory and antimicrobial actions.

The molecular formula is often cited as C28H36S5O6(NH4)2, but this is an approximation reflecting the average composition rather than a discrete molecular structure. The presence of these sulfur-containing functional groups is key to its multifaceted activity.

Physicochemical Properties and Their Implications

The physical and chemical properties of Ammonium Sulfobituminate dictate its handling, formulation, and application:

  • Appearance: The characteristic dark brown to black, viscous liquid is due to the complex organic nature and the presence of sulfur compounds.
  • Odor: Its strong, bituminous odor is unmistakable and stems from its shale oil origin and sulfur content.
  • Solubility: Its solubility in water and glycerol makes it well-suited for aqueous or glycerol-based topical formulations. Its insolubility in oils limits its use in purely oil-based systems.
  • Stability: Ichthammol can be incompatible with strong acids, bases, and certain metal salts (e.g., iron salts), which can lead to decomposition or precipitation. Therefore, careful pH control and excipient selection are crucial during formulation.

As a manufacturer, we ensure our production processes yield Ammonium Sulfobituminate that consistently meets established standards for these properties. This reliability is critical for our clients in the pharmaceutical and cosmetic industries who depend on predictable ingredient performance.
