Product: Ethylene Glycol Monostearate (EGMS)
Rchem Ethylene Glycol Monostearate (EGMS) is a high-purity, non-ionic pearlizing and opacifying wax, presented as white flakes or beads. This versatile ester is a fundamental ingredient for imparting a luxurious, pearlescent shine and rich, opaque appearance to a wide range of cosmetic and personal care formulations. Beyond its aesthetic role, EGMS also functions as an effective emulsion stabilizer and viscosity modifier, contributing to the texture and stability of creams, lotions, and surfactant-based products.

Frequently Asked Questions:
What is the difference between EGMS and EGDS (Ethylene Glycol Distearate)?
The primary difference is the number of stearic acid chains attached to the ethylene glycol molecule. EGMS (Monostearate) has one stearic acid chain, while EGDS (Distearate) has two. EGDS generally provides a more intense pearlescent effect and is more commonly used as a primary pearlizer. EGMS offers a softer pearl and can function more effectively as a co-emulsifier and stabilizer.
EGMS 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.
How should EGMS be incorporated into a formulation?
No. EGMS 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 EGMS be used in clear products?
The "stearate" 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.
Why is EGMS marked as "Palm-Derived"?
Yes, EGMS is considered safe for use in rinse-off and leave-on cosmetic products as a pearlizing and opacifying agent. It is widely used globally and complies with major international cosmetic regulations.
