For a professional who develops products, whether perfumes, handmade candles, or cosmetics, the biggest frustration is creating a formula that, after a few months on the shelf, develops an altered odor.
At Olfacta Labs, our focus is not just on the immediate impact of a fragrance, but on its long-term chemical integrity. Understanding olfactory stability is what separates an amateur product from a product of international standard.
What is olfactory stability in formulation?
Stability refers to the resistance of an olfactory composition to external agents. When a fragrance "changes," it means that the molecules that compose it have collapsed or reacted in an undesirable way with the environment.
Why do fragrances lose quality?
1. Oxidation and Chemical Interaction
The components of a fragrance are chemically active. If the raw material is not purified in a laboratory, it reacts with oxygen as soon as the bottle is opened. The result? Top notes that lose their brightness and base notes that take on a metallic or rancid aspect. At Olfacta Labs, we test oxidation resistance to ensure that the material maintains its sensory profile.
2. Degradation by Light (Photosensitivity)
Many aromatic compounds are sensitive to UV radiation. If the substance does not have a stable molecular structure, exposure to light alters the liquid's color and aroma balance. This is critical for those who market products in transparent packaging.
3. The Purity of Fixatives and Solvents
The solvent is the vehicle for the aroma. Low-quality solvents evaporate unevenly, "sequestering" certain notes and leaving others behind. Stability requires fixatives that ensure the olfactory pyramid remains intact from the moment of production until final consumption by the customer.
Consistency: The Challenge of the Professional Batch
The biggest challenge for a flavor specialist is repeatability. A professional product requires that batch number 1 be chemically identical to batch number 100. Without rigorous laboratory control (chromatography), natural variations in raw materials can alter the final result of your product.
Olfacta Labs Standard
We don't just sell fragrances; we deliver technically stable formulas. Our rigorous laboratory testing ensures that professionals can be confident their creations will not undergo unwanted alterations, maintaining the trust of the end consumer.
