What it is
A proprietary fragrance blend identified by the F.I.L. (Fragrance Ingredient List) code b49725/1, used to provide a specific scent profile in cosmetics.
How it works
It works by releasing volatile aroma molecules that interact with olfactory receptors, creating a pleasant scent. In a product, it masks any base odors and enhances the user experience.
Pros
Consistent scent
Manufacturers can rely on this pre-blended mix to deliver the same fragrance every batch, so you get a predictable product experience.
Low comedogenic risk
Fragrance blends like this are unlikely to clog pores, making them suitable for acne-prone skin as long as no irritation occurs.
Cons and cautions
Potential irritant
Fragrance is one of the most common causes of contact dermatitis. Even at low concentrations, this blend may cause redness, itching, or stinging on sensitive skin.
Undisclosed allergens
The exact composition is proprietary, so you cannot know which specific aroma chemicals are inside. This makes it harder to avoid known allergens like limonene or linalool.

Usage tips
