CAS Number: N/a
DESCRIPTION
What It Does: Provides authentic nacre iridescence and mineral conditioning from genuine pearl powder.
Why It's Used: Ultimate luxury pearlescent ingredient โ authentic pearl nacre providing genuine pearl optical effect with luxury chinese and japanese beauty heritage.
How It Works: Aragonite calcium carbonate platelets in organic matrix provide nacre's iridescence from thin-film light interference (same mechanism as mica-tio2 pearlescent pigments but from biological structure). calcium from aragonite provides mineral conditioning.

SCIENTIFIC NOTE
Pearl nacre's iridescent colour arises from the same thin-film interference as mica-tio2 pearlescent pigments, but the nacre's biological self-assembly creates a perfectly ordered aragonite platelet stack with nanometre-precise thickness control exceeding any industrial coating process. this biological precision provides an optical perfection in natural pearl that synthetic pearlescent pigments approximate but cannot exactly replicate.
