There is suppposed to be a substitute for whale blubber in perfume what it?

You're likely thinking of ambergris, a waxy substance produced by sperm whales. It was historically used in high-quality perfumes for its unique, sweet, and earthy scent.

However, ambergris is no longer commonly used in perfumes. It's now considered ethically problematic due to its origin from endangered species and its unsustainable harvesting practices.

Instead, perfumers now use synthetic ambers, which are lab-created compounds that mimic the scent profile of ambregris without harming whales. These synthetics are just as effective and often even more versatile, allowing for a broader range of olfactory possibilities.

So, while there isn't a specific "substitute" for whale blubber (which is not used in perfume), the synthetic ambers are a sustainable and ethical replacement for ambergris.
