Formulation Tips:
-
EGDS is typically melted and added to the oil phase of formulations
-
For pearlescent effect, EGDS must be crystallized upon cooling
-
Uniform cooling is essential for consistent pearlescence
-
Compatible with most anionic, cationic, and nonionic surfactants
-
Works synergistically with surfactants to create pearl luster
-
Typically used at 1-5% concentration
SECTION 7: PEARLESCENT EFFECT FORMATION
| Parameter | Description |
|---|---|
| Formation Process | EGDS is melted and dispersed in the formulation |
| Crystallization | Upon cooling, EGDS forms platelet crystals |
| Light Reflection | Platelet crystals reflect light, creating a pearlescent effect |
| Cooling Rate | Slow cooling produces larger crystals and more intense pearlescence |
| Surfactant Interaction | Surfactants help stabilize the crystal suspension |
| Temperature | Optimal pearlescence obtained between 35-45°C |
Pearlescence Mechanism:
-
EGDS is heated to melting temperature (>75°C)
-
Incorporated into formulation with surfactants
-
Slowly cooled to ambient temperature
-
EGDS crystallizes into microscopic platelets
-
Platelets reflect light, creating pearl-like luster
