For chemical industry professionals involved in procurement, R&D, and product formulation, a thorough understanding of chemical specifications is non-negotiable. Sucrose Fatty Acid Esters, identified by CAS number 37318-31-3, are a key ingredient with diverse applications, particularly in the cosmetic and food sectors. This article provides a detailed breakdown of the specifications for this compound, guiding B2B buyers in their selection process and highlighting the importance of sourcing from reliable manufacturers and suppliers.

The primary identifier for this particular Sucrose Ester is its CAS number: 37318-31-3. This unique numerical code is essential for accurate identification and procurement in the global chemical market. Beyond the CAS number, key physical and chemical properties define the suitability of this ingredient for specific applications. Typically, Sucrose Esters conforming to these specifications are presented as a white to slightly yellow powder or solid. This form factor is advantageous for handling and incorporation into various formulations.

Solubility is another critical parameter. Sucrose Esters with CAS 37318-31-3 exhibit good water solubility, often cited as 540 g/L at 20°C. This characteristic makes them highly effective as emulsifiers and solubilizers in aqueous systems, a common requirement in cosmetic lotions, creams, and food products like beverages and dressings. The pH of a 50g/L solution in water is typically in the range of 3.5-5.0, indicating a slightly acidic nature, which is important to consider during formulation stability testing.

The density is specified as 1.2 ± 0.1 g/cm³, and a specific gravity of 1.48. While a melting point is not explicitly stated as a low figure, the high boiling point of 756.9 ± 60.0 °C at 760 mmHg suggests a robust compound. Importantly, this material is often available in Food Grade, signifying its suitability and safety for consumption or use in food products, as well as for high-quality cosmetic applications. Understanding these grades is vital for compliance and product integrity.

When looking to purchase Sucrose Fatty Acid Esters (CAS 37318-31-3), B2B buyers should seek out suppliers who can provide comprehensive technical documentation, including Material Safety Data Sheets (MSDS) and Certificates of Analysis (CoA). Sourcing from manufacturers in China can offer competitive pricing, but it is essential to verify the supplier's credentials, export experience, and quality assurance processes. Direct communication with potential suppliers to confirm specifications, discuss bulk pricing, and arrange for samples is a standard and recommended practice for any serious buyer in the chemical industry.
