Product Description
What Is Ethylene Glycol Distearate?
Ethylene glycol and stearic acid are esterified to produce ethylene glycol distearate (EGDS), a waxy substance. It is frequently utilized as a surfactant and emulsifier in industrial, personal care, and cosmetic goods. EGDS plays a key role in stabilizing emulsions, improving texture, and enhancing the spreadability of formulations like creams, lotions, shampoos, and body washes. In order to maintain product consistency and avoid phase separation, it aids in the mixing of water-based and oil-based constituents.
Preparation of EGDS involves the esterification of two molecules of stearic acid with one molecule of ethylene glycol, typically in the presence of a catalyst. In order to promote the ester’s synthesis and eliminate water as a byproduct, the reaction is conducted at high temperatures (160°C to 200°C). The resulting product is purified by neutralization and filtration. Because of its superior emulsifying and stabilizing qualities, EGDS is typically utilized in formulations at low doses.

Ethylene Glycol Distearate Has Wide Range of Uses:
- Cosmetics & Skincare: EGDS is primarily used as an emulsifier in creams, lotions, and body washes to stabilize oil-water mixtures. It helps improve texture and spreadability, ensuring smooth application. It also acts as a stabilizer, maintaining consistency in emulsions.
- Hair Care: In shampoos and conditioners, EGDS functions as both an emulsifier and stabilizer, ensuring even distribution of ingredients and preventing separation.
- Pharmaceuticals: EGDS is used in topical creams and ointments, where it provides improved texture and stability, helping to maintain a uniform formulation.
- Personal Care: It is incorporated in deodorants and shaving creams, enhancing texture and improving the product’s spreadability.
- Food & Textiles: In the food industry, EGDS acts as a dispersing agent, and in textiles, it serves as a lubricant to improve processing efficiency.
User Asked Question:
Q: How does EGDS differ from Glyceryl Stearate?
A: Both EGDS and Glyceryl Stearate are emulsifiers, but they are derived from different alcohols. Glycerin is the source of Glyceryl Stearate, whereas ethylene glycol is the source of EGDS. EGDS is often more effective as a stabilizer in emulsions, whereas Glyceryl Stearate is milder and commonly used in more gentle formulations.
