The visual and tactile properties of personal care products are critical for consumer engagement. Behind the shimmering appearance of many shampoos and lotions lies a fascinating ingredient: Ethylene Glycol Distearate (EGDS). For professionals seeking to understand and procure this compound, knowing its chemical basis and sourcing options is essential. If you're looking to buy EGDS, consulting with a specialized manufacturer in China, such as NINGBO INNO PHARMCHEM CO.,LTD., can provide valuable insights and a reliable supply.

Understanding the Chemical Structure and Function of EGDS

Ethylene Glycol Distearate (EGDS), with its CAS number 627-83-8, is chemically classified as a diester. It is formed through the esterification reaction between one molecule of ethylene glycol and two molecules of stearic acid. This molecular structure is key to its performance. The ester linkages and the long fatty acid chains (from stearic acid) contribute to its waxy solid form and its insolubility in water but solubility in oil and surfactant systems. In formulations, EGDS crystallizes upon cooling, forming platelet-like structures that reflect light, thus creating the desirable pearlescent and opacifying effects. Its ability to function as a thickener and emollient further adds to its value in cosmetic and detergent applications.

Key Properties and Benefits:

  • Chemical Nature: Diester of ethylene glycol and stearic acid.
  • Functional Roles: Pearlescent agent, opacifier, thickening agent, emollient.
  • Appearance Enhancement: Creates a milky, shimmering visual effect.
  • Textural Improvement: Provides a smooth feel and contributes to product body.
  • Supplier Advantage: Purchasing from experienced manufacturers ensures quality.

When you are seeking to buy EGDS, understanding its specifications, such as acid value, saponification value, and diester content, is important. A high diester content (typically 93% or more) indicates greater efficiency as a pearling agent. For procurement managers, identifying a supplier in China that can consistently deliver these specifications is crucial for product development and manufacturing continuity.

Sourcing EGDS: What You Need to Know

The process of incorporating EGDS into finished products usually involves heating the ingredient to melt it and then dispersing it within the formulation, typically during the cooling phase to achieve optimal crystallization for pearlescence. The optimal temperature range for addition is usually below 50°C. For companies asking how to buy EGDS, considering the technical support offered by the manufacturer is also beneficial.
