SECTION 7: PEARLESCENT EFFECT MECHANISM
| Parameter | Description |
|---|---|
| Mechanism | Glycol distearate crystallizes upon cooling to form platelet crystals |
| Light Reflection | Platelet crystals reflect light, creating a pearlescent sheen |
| Crystal Formation | Slow cooling produces larger crystals and more intense pearlescence |
| Temperature Effect | Heating above melting point dissolves crystals; cooling reforms them |
| Surfactant Interaction | Surfactants help stabilize the crystal suspension |
| pH Effect | Stable in pH 6.0 – 8.0 range |
Pearlescence Formation Process:
-
Pearlizer is incorporated into the formulation
-
Upon cooling, glycol distearate crystallizes
-
Platelet crystals form a layered structure
-
Light is reflected and refracted by the crystals
-
Pearlescent shimmer is created
