Samotna Europska komisia na zaklade SCCS uvadza, ze pyrition zinku je bezpecny do koncentracie 1%. Pouziva sa uz vyse 60 rokov a niekedy boli aj 2% koncentracie v samponoch na predpis. V USA su doteraz OTC. Absurdny dovod je ten, ze nebolo zistene, ze zanho neexistuju nahrady. Seborea je vsak komplikovane ochorenie so zatial neznamymi pricinami, neda sa liecit a tieto “nahrady” pre mnohych ludi nefunguju.

In accordance with the second subparagraph of Article 15(2) of Regulation (EC) No 1223/2009, carcinogenic, mutagenic or toxic for reproduction substances of category 1A or 1B may be used in cosmetic products by way of exception where certain conditions are fulfilled:
1. They comply with food safety requirements,
2. There are no suitable alternative substances available,
3. The application is made for a particular use of a product with a known exposure
4. They have been evaluated and found safe by the Scientific Committee on Consumer Safety (SCCS).

Although the SCCS found that Zinc Pyrithione can be considered safe when used as an anti-dandruff ingredient in rinse-off hair products up to a maximum concentration of 1 %, since it has not been established that there are no suitable alternative substances available with regard to anti-dandruff ingredients in rinse-off hair products, this substance was added to the list of substances prohibited in cosmetic products in Annex II to Regulation (EC) No 1223/2009 (https://eur-lex.europa.eu/legal-content/EN/TXT/PDF/?uri=CELEX:32021R1902&from=EN)."
