For the dedicated R&D scientist, understanding the fundamental chemistry of the ingredients they use is key to unlocking new product potentials. Today, we offer a chemical deep dive into Pentaerythityl Tetraisostearate (CAS 62125-22-8), a complex ester with a unique structure and valuable properties. As a specialized chemical manufacturer, we provide this high-quality ingredient, enabling scientific exploration and product innovation. For those seeking to purchase this compound, understanding its synthesis and properties is essential.

Pentaerythityl Tetraisostearate is formed through the esterification of pentaerythritol, a tetrahydric alcohol, with four molecules of isostearic acid. The resulting molecule is a large, branched ester with a molecular weight of approximately 1201.99 g/mol. This tetraesterification results in a highly stable compound with a characteristic transparent liquid appearance and a high LogP value (estimated at 32.456), indicating its lipophilic nature.

The synthesis process involves reacting pentaerythritol with isostearic acid under controlled conditions, typically with an acid catalyst. Achieving a high degree of esterification is crucial for the final product's performance. As a manufacturer, we employ rigorous quality control measures throughout the synthesis and purification stages to ensure that our Pentaerythityl Tetraisostearate meets the highest purity standards. This is vital for R&D scientists who require precise chemical inputs for their experiments.

The inherent properties of Pentaerythityl Tetraisostearate – its excellent emolliency, solvency, and emulsifying capabilities – stem directly from its molecular architecture. The long, branched isostearate chains contribute to its low melting point, resulting in its liquid state at room temperature and providing a smooth, non-greasy feel upon application. This makes it an attractive emollient for cosmetic formulations where sensory experience is paramount.

Beyond cosmetics, its structure makes it a useful monomer or intermediate in the synthesis of functional polymers, lubricants, and other specialty chemicals. The ester linkages can potentially be cleaved or modified in further reactions, allowing for the creation of diverse chemical entities. For any researcher or procurement manager looking to buy Pentaerythityl Tetraisostearate for such advanced applications, engaging with a knowledgeable supplier is key. We offer competitive pricing and technical support for our manufactured products, encouraging you to reach out for detailed specifications and purchase inquiries.
