General Description:
Ethylene Glycol Distearate (EGDS) is an organic compound derived from the esterification of ethylene glycol with stearic acid, a long-chain fatty acid. It typically appears as a waxy solid or flakes at room temperature and is insoluble in water but soluble in oils and organic solvents.
Uses in the Cosmetic Industry:
In the cosmetic industry, Ethylene Glycol Distearate serves several essential functions in formulations, including:
- Emollient: EGDS acts as an emollient, imparting a smooth and soft feel to the skin by forming a protective barrier on its surface. It helps to lock in moisture and prevent dehydration.
- Surfactant: It functions as a surfactant in cosmetic products, facilitating the dispersion of oil and water-based ingredients. This property is particularly useful in cleansers, shampoos, and body washes.
- Opacifying Agent: EGDS is used as an opacifying agent in cosmetic formulations, providing a pearlescent or opaque appearance to products like shampoos, shower gels, and lotions.
- Thickener: It can act as a thickening agent in creams, lotions, and conditioners, improving the viscosity and texture of the product.
- Stabilizer: EGDS helps to stabilize emulsions by preventing the separation of oil and water phases in formulations like creams and lotions.
- Cleansing Agent: In cleansers and shampoos, EGDS helps to cleanse the skin and hair by removing dirt, oil, and impurities.
Hazard:
While Ethylene Glycol Distearate is generally considered safe for use in cosmetics, there are some potential hazards and considerations:
- Skin Irritation: Direct contact with concentrated EGDS may cause skin irritation or sensitization in individuals with sensitive skin. It is advisable to use products containing EGDS as directed and discontinue use if irritation occurs.
- Eye Irritation: Contact with the eyes can cause irritation. Care should be taken to avoid eye exposure, and immediate rinsing is recommended if contact occurs.
- Environmental Impact: Ethylene Glycol Distearate is not readily biodegradable and can persist in the environment. Proper disposal practices and wastewater treatment are essential to minimize environmental impact.
CAS Number: 627-83-8
INCI: Ethylene Glycol Distearate
Composition: Ethylene Glycol Distearate is composed of two stearic acid molecules esterified with ethylene glycol. Its chemical formula is C38H74O4.
Purity Grade: No purity grade applicable
Appearance: Ethylene Glycol Distearate typically appears as a white to slightly yellowish, waxy solid or flakes at room temperature.
Solubility: Ethylene Glycol Distearate is practically insoluble in water but soluble in organic solvents such as ethanol, ether, and chloroform. It disperses in water to some extent, forming opaque or pearlescent suspensions.
Preservation: Ethylene Glycol Distearate itself does not possess preservative properties. However, it is typically used in formulations alongside other preservatives to prevent microbial growth and ensure product stability.
Storage: Store in a closed container at a dry place at room temperature
Raw Material Source: The raw materials for Ethylene Glycol Distearate synthesis include stearic acid and ethylene glycol, both of which can be derived from natural sources such as vegetable oils or petroleum.
Manufacture: Ethylene Glycol Distearate is synthesized through the esterification reaction between stearic acid and ethylene glycol in the presence of a catalyst. The reaction produces Ethylene Glycol Distearate along with water as a byproduct. The resulting product is then purified and processed into the desired form, such as flakes or pellets.

Proposition: E.G.D.S complies with relevant regulations and guidelines.
Warning: Avoid contact with eyes and skin. Use appropriate protective equipment when handling.
THE STORY OF ETHYLENE GLYCOL DISTEARATE (EGDS)
EGDS: The Pearlizing Agent that Adds Shine, Smoothness & Luxury
EGDS (Ethylene Glycol Distearate) is a pearlizing and opacifying agent used in shampoos, body washes, and cleansers to create a creamy, luxurious, pearlescent appearance.
It also acts as a skin-conditioning emollient, improving texture, smoothness, and viscosity in surfactant-based systems.
A Stearic Acid Ester Crafted for Aesthetic Enhancement
EGDS is produced through the esterification of:
• Ethylene glycol
• Stearic acid (vegetable-derived fatty acid)
The result is a waxy, white crystalline solid known for creating shimmering pearl effects in liquid cleansers.
TRCkem supplies high-purity cosmetic-grade EGDS with excellent dispersibility in surfactant systems.
Pearlize. Condition. Beautify.
EGDS delivers multiple formulation benefits:
✅ Creates creamy pearlescent shine in surfactant formulas
✅ Improves texture, thickness, and visual appeal
✅ Adds light emolliency for smoother skin feel
✅ Enhances long-term stability of cleanser systems
Used in: shampoos, body washes, face cleansers, moisturizing shower gels, and baby bath products.
Easy-to-Use, Stable & Ideal for Surfactant Systems
• Typical use level: 0.5–3%
• Melt EGDS into the heated surfactant phase (60–70°C)
• Pearl effect fully develops when the formula cools
• Compatible with SLES, SLS, Betaine, Glucosides & most surfactants
• Safe, non-irritating, and biodegradable fatty ester
• Store in cool, dry conditions away from moisture
• Approved globally for cosmetic applications
