For procurement managers and R&D scientists in the chemical industry, understanding the precise properties of raw materials is fundamental to successful product development and manufacturing. Glyceryl Hydrogenated Rosinate, identified by its CAS number 8050-31-5, is a versatile ester gum with a unique profile of characteristics that make it valuable across various industrial applications. As a dedicated manufacturer and supplier of fine chemicals, we provide detailed insights into the materials we offer, ensuring our clients can make informed purchasing decisions.

Chemical Identity and Composition

Glyceryl Hydrogenated Rosinate is chemically described as the glycerol ester of highly hydrogenated wood rosin. This means that the natural rosin acids, typically derived from pine trees, have undergone a process of hydrogenation to saturate their double bonds. This saturation is key to its enhanced stability. Subsequently, these hydrogenated rosin acids are esterified with glycerol, forming a stable and pale resin. Its molecular weight is approximately 376.54 g/mol, and it is registered under EINECS number 232-482-5. The synonyms listed, such as ENDERE S, ESTAR GUM 8 BG, and STAYBELITE ESTER 10, highlight its common presence in the market under various trade names.

Key Physical and Chemical Properties

  • Appearance: The product is typically described as a slightly yellow solid. The physical form can vary, with pastilles or flakes being common.
  • Solubility: It is generally insoluble in water but exhibits good solubility in many organic solvents, which is crucial for its incorporation into various liquid formulations.
  • Oxidation and Heat Resistance: This is perhaps its most significant advantage. The hydrogenated nature of the rosin ester provides exceptional resistance to oxidation, preventing degradation and discoloration when exposed to air, heat, and light over time. This makes it ideal for applications where long-term stability is required.
  • Color Stability: It is renowned for its pale color and excellent color retention, a critical factor for transparent or light-colored products.
  • Tackiness: It possesses inherent tackiness, making it an excellent tackifier resin for adhesive applications.
  • Softening Point: Typically in the range of 80-88 °C (Pinova drop method), indicating its thermoplastic nature and suitability for hot melt applications.
