Preferred Fragrance Families / Combinations
Because BHT is low-odor and nonreactive (within recommended use levels), it pairs especially well with fragrance types that are vulnerable to oxidation:
-
Citrus / Fresh notes (e.g. lemon, bergamot, orange) — helps prevent “off sour” odors
-
Aldehydic / ozonic accords — maintains crispness
-
Delicate florals (rose, jasmine, lily) — preserves brightness & prevents discoloration
-
Green / herbal notes (e.g. galbanum, leaves) — helps retain their fresh green character
-
Woody / resins / oud blends — protects against gradual rancid or stale transitions
Comparison Table: Sarochem™ BHT vs. Other Brands
Feature Sarochem™ BHT Generic/Other Brands Purity 99.9% 95–98% Appearance White crystalline Yellowish / impure Odor Impact Neutral Slight chemical note Solubility Excellent in oils & alcohols Moderate Shelf Life Extension Long-lasting Medium Application Range Perfumes, cosmetics, oils, candles Limited
In practice, BHT should be used at low concentration levels (typically 0.01% – 0.1 % w/w, depending on the system) so that it does not interfere with scent or stability.
