Selenium sulfide is a chemical compound used in some dandruff shampoos and antifungal treatments because it helps control flaking and fungal growth. It is also found in certain industrial processes, such as glass manufacturing and rubber production. California's Proposition 65 program lists selenium sulfide as a substance known to cause cancer, based on scientific evidence from animal studies. The listing, effective since 1988, means products containing it must carry a warning label in California if exposure levels are significant. This does not mean you will get cancer from occasional use—it simply reflects regulatory caution. The source for this information is the California Office of Environmental Health Hazard Assessment (OEHHA) Proposition 65 list.

Selenium is a naturally occurring element that, in certain forms, can be toxic. In cosmetics, selenium and most of its compounds are banned under EU regulations because of potential health risks. The exception is selenium disulphide, which is allowed only under strict conditions, such as in anti-dandruff shampoos at low concentrations. Selenium is sometimes used in industrial settings or as a dietary supplement, but in personal care products, it is restricted to prevent skin irritation or more serious effects. The EU Cosmetics Regulation (EC) No 1223/2009 lists selenium and its compounds in Annex II as prohibited substances, meaning they cannot be added to cosmetic products sold in the EU. This rule helps protect consumers from unnecessary exposure. For more details, see the EU CosIng database at https://ec.europa.eu/growth/tools-databases/cosing/.

2-(4-tert-butylbenzyl)propionaldehyde is a chemical used as a fragrance ingredient in products like perfumes, cosmetics, and cleaning agents. It is also known by the alias "2-propionaldehyde" and belongs to a group of substances called stereoisomers. The European Chemicals Agency (ECHA) lists this substance on the Candidate List of Substances of Very High Concern (SVHC) under the EU REACH regulation because it is classified as a potential endocrine disruptor, meaning it may interfere with hormone systems in humans and wildlife. This classification does not mean it causes harm in every product, but it triggers a legal duty for companies to inform consumers and regulators about its presence. The regulation aims to encourage safer alternatives and reduce long-term exposure. For more details, see the ECHA Candidate List at https://echa.europa.eu/candidate-list-table.
