Ambergris, commonly referred to as whale vomit, is a solid, waxy, flammable substance produced in the digestive system of sperm whales. It is highly valued by perfumers as a fixative, allowing scents to last longer. The substance is rare and expensive, with its collection and sale regulated by varying laws worldwide. While it was historically used in perfumes, it has largely been replaced by synthetic alternatives due to its rarity and legal ambiguity.

Ambergris, a waxy substance produced by sperm whales, is used in perfume
Ambergris is a waxy, flammable substance produced by sperm whales. It is a rare byproduct of the sperm whale's squid-based diet, formed in the bile duct in the intestines of the whale. It is speculated that an ambergris mass too large to pass through the intestines is expelled via the mouth or the other end, although this is debated.
When first expelled by the whale, ambergris is soft, pale white or black in colour, and has a strong fecal odour. Over time, the substance hardens and develops a crusty, waxy texture and a sweet, earthy scent. This scent has been described as a rich and smooth version of isopropanol without its harshness.
Ambergris has been used in perfume for centuries, although it is a rare and expensive ingredient. It is also known as 'floating gold' and 'whale vomit', although it is not technically vomit. Perfumers extract an odourless alcohol called ambrein from the ambergris, which is used as a base note to make the scent of the perfume last longer. The finest perfumes are made from pure white varieties of ambergris, which have the highest levels of ambrein.
Whaling was once a widespread industry, with sperm whales hunted for their oil, whalebone, and ambergris. However, whales are now protected worldwide, and the trade of ambergris is banned in many countries. Today, most perfumes use synthetic alternatives to ambergris, such as ambroxide, due to the difficulty and expense of sourcing the natural substance.

Ambergris is passed like faecal matter, but some believe it is vomited
Ambergris is a substance produced by sperm whales that has been used in perfumes for centuries. It is sometimes referred to as "whale vomit", but this is a misnomer. While some people believe that ambergris is regurgitated by whales, most sources indicate that it is passed like faecal matter.
Richard Sabin, Principal Curator of Mammals at the Natural History Museum, holds the latter view. He believes that ambergris forms in the intestines and passes along with faecal matter, forming an obstruction in the rectum. Some think the whale will eventually pass the mass, while others believe that the obstruction grows so large that it ruptures the whale's rectum, leading to the whale's death.
The confusion about the nature of ambergris may stem from the fact that sperm whales do regurgitate the beaks and pens of the squid they eat. These indigestible parts are vomited out before digestion. However, ambergris itself is now understood to be a secretion of the bile duct in the intestines of the sperm whale. It can be found floating on the sea or washed up on coastlines, and only a small percentage of sperm whales produce it.
The colour of ambergris indicates its quality for use in perfumes. The finest perfumes are made from pure white varieties, which have the highest concentration of ambrein, an odourless alcohol that is extracted from ambergris and used to make a perfume's scent last longer. Black ambergris, on the other hand, has the lowest concentration of ambrein and is therefore the least valuable.
In summary, while ambergris has been colloquially referred to as "whale vomit", it is now understood to be passed like faecal matter by sperm whales. The debate surrounding the expulsion of ambergris highlights the ongoing scientific inquiry into the mysterious nature of this valuable substance.

Ambergris is rare and expensive, and only around 1% of sperm whales produce it
Ambergris is a rare and expensive substance, produced by only around 1% of sperm whales. It is formed in the bile duct in the intestines of the sperm whale and is passed like faecal matter. It is sometimes found in the abdomens of dead sperm whales.
The origin of ambergris was a mystery for many years, with several theories proposed, including that it was hardened sea foam or the droppings of large birds. It was only when large-scale whaling began in the 1800s that the sperm whale was identified as the producer of this substance.
There are conflicting opinions as to how ambergris is expelled from the whale. Some believe that it is regurgitated, earning it the nickname 'whale vomit'. However, others, including the Natural History Museum's Principal Curator of Mammals, Richard Sabin, believe that it is formed in the intestines and passed along with faecal matter.
Ambergris is highly valued by perfume makers as a fixative that allows the scent to last much longer. It has been used in perfumes for centuries, although today, it is mostly replaced by synthetic alternatives due to its rarity, expense, and legal ambiguity.
The quality of ambergris is determined by its colour, with the finest perfumes made from pure white varieties, which have the highest concentration of ambrein, an odourless alcohol extracted from ambergris. Black ambergris, on the other hand, has the lowest concentration of ambrein and is therefore the least valuable.

Ambergris is processed to extract odourless alcohol (ambrein) which acts as a base note
Ambergris is a highly valued, rare, and expensive substance produced by sperm whales. It is sometimes referred to as "whale vomit", although this is a misnomer. It is believed to be formed in the intestines of the whale, possibly as a means of protecting the whale's internal organs from the sharp beaks of squids, which are a staple part of the sperm whale's diet.
The colour of ambergris indicates its quality, with the finest perfumes using pure white varieties, which have the highest concentration of ambrein. Black ambergris is the least valuable as it contains the least amount of ambrein.
Before ambergris can be used in perfumes, it must be processed to extract an odourless alcohol called ambrein. Ambrein is one of the base notes of the perfume and helps to make the scent last longer. Ambrein breaks down into the valuable aromatic components of ambergris, ambrinol and ambroxide, which can now be inexpensively synthesized. This has led many perfume makers to move away from using ambergris due to the slim chances of finding it and the legal ambiguity involved in its collection and sale.

Whale hunting for ambergris and other products was common, but whales are now protected
Whale hunting was once a common practice, with nearly 50,000 whales, including sperm whales, killed each year during the peak of the whaling industry in the 18th and 19th centuries. Sperm whales were specifically targeted for their valuable products, including whale oil, whalebone, and ambergris. Whale oil was used for lighting lamps and making soap, while ambergris, a waxy substance produced in the whale's digestive system, was highly prized in the perfume industry for its ability to make scents last longer.
However, the negative impacts of whaling became increasingly evident, with whale populations declining to concerning levels. Whaling not only threatened the survival of whales but also disrupted the health of marine ecosystems, as whales play a crucial role in maintaining the ecological balance. In response, a global effort to protect and conserve whales emerged, led by organisations such as the American Cetacean Society, Ocean Alliance, the Whale Center, and the Connecticut Cetacean Society. Their campaigns highlighted the intelligence and endangered status of whales, as well as the inhumane methods used in whaling.
As a result of these conservation efforts, whales are now protected worldwide. The International Whaling Commission (IWC) instituted a moratorium on commercial whaling in 1982, which came into force in 1986. This ban on hunting has saved hundreds of thousands of whale lives and is considered a significant achievement in species conservation. While most countries abide by this moratorium, a few nations, including Japan, Norway, and Iceland, continue to defy the ban for economic reasons.
Today, whales face various threats beyond hunting. Climate change, plastic ingestion, fishing gear entanglement, marine pollution, and shipping collisions all pose significant dangers to whale populations. Whale conservation organisations continue to advocate for the protection of critical habitats, the reduction of human-generated noise, and the establishment of whale sanctuaries to ensure the long-term survival of these majestic creatures.
While whale hunting may have once been common, the recognition of the importance of whales in our ecosystems and the ethical considerations surrounding their exploitation have led to their protected status today.
