Product: Ethylene Glycol Distearate (EGDS)
Rchem Ethylene Glycol Distearate (EGDS) is a high-purity, pearlescent wax ester, presented as white flakes or beads. This versatile non-ionic opacifier and pearlizing agent is a cornerstone ingredient for creating luxurious, opaque, and visually appealing cosmetic and personal care formulations. When incorporated into emulsions and surfactant systems, EGDS crystallizes upon cooling to produce a brilliant, pearlescent luster and a rich, creamy opacity, significantly enhancing the aesthetic and perceived value of the final product.

Frequently Asked Questions:
How does EGDS create a pearlescent effect?
The pearlescent effect is a physical phenomenon. When added to a hot formulation and then cooled, EGDS crystallizes into tiny, flat, plate-like crystals. These crystals align in parallel layers within the product. Light hitting these plates is reflected and refracted, creating the characteristic shimmer and pearl-like glow.
EGDS must be added to the heated water or surfactant phase (typically between 65-75°C) with good agitation. It must be fully melted and dispersed. The pearl effect develops as the formulation is slowly cooled under continuous, gentle stirring. Rapid cooling or high-shear mixing can disrupt crystal formation and weaken the pearl effect.
What is the correct method to incorporate EGDS into a formulation?
No. EGDS is an opacifier and pearlizer. Its primary function is to make formulations opaque and pearlescent. It should not be used in products where clarity is desired.
Can EGDS be used in clear formulations?
The "distearate" part of the molecule is an ester of stearic acid. A common industrial source of stearic acid is palm oil. If a non-palm derived version is required for your brand's sustainability policy, it is essential to inquire with your supplier about the specific source of the fatty acid or explore alternative pearlizers.
Why is EGDS marked as "Palm-Derived"?
How does EGDS differ from other pearlizing agents like Glycol Distearate? Ethylene Glycol Distearate (EGDS) and Glycol Distearate are often used interchangeably, as "Glycol" typically refers to Ethylene Glycol in this context. They are generally the same compound. It's important to confirm the specific chemical identity with your supplier, but in most cosmetic applications, they refer to the same pearlizing wax.
