Phenols love sweets and often make their own treats to enjoy. However, some of these have unusual effects, some are not edible for humans, some are not even considered as food. To facilitate smooth human-phenol relations in the future, Phenol Institute has classified them as "S³ (Special Sweet-like Substance)" and is documenting them accordingly.
Each substance is named in this format: S³-{found date} "{identification name}". If more than one is found in the same day, a numbering is added after the date.
Currently, there are five classes:
1. Sweet (probably safe) – affects only Phenols. Humans can eat it as ordinary food.
2. Mild (active on humans) – affects humans when ingested, but causes no harm through mere exposure.
3. Spicy (dangerous) – affects humans even through non-ingestive contact (e.g. sight, touch, or proximity). May also possess minor behavioral intent.
4. Naraka (highly dangerous) – has the potential to cause planetary-scale disasters, or possesses advanced intelligence.
5. Samvarta (oh no) – actively seeks to destroy Earth, the cosmos, or human civilization.
As of March 2025, there are no class-5 Special Sweet-like Substances.
