  • Sources/Uses: Occupational exposures occur during mining, milling and processing of some zeolites as well as during agricultural work in areas in which soils are contaminated with erionite. [IARC] Zeolites are used in water softeners, detergents, cracking catalysts, adsorbents, desiccants, and solar collectors; [Hawley] Zeolites are used for pet litter, soil conditioners, animal feed, waste-water treatment, gas absorbents, etc. Erionite deposits exist in Arizona, Nevada, Oregon, and Utah. [NTP] Workers may be exposed in waste treatment, agricultural waste, air pollution control systems, cement aggregates, and building materials; [Siemiatycki, p. 326] Source: Haz-Map, Information on Hazardous Chemicals and Occupational Diseases
  • Restricted Notes: Erionite is no longer commercially mined; [NTP] Source: Haz-Map, Information on Hazardous Chemicals and Occupational Diseases
  • Industrial Processes with risk of exposure: Farming (Respiratory Hazards) [Category: Industry] Source: Haz-Map, Information on Hazardous Chemicals and Occupational Diseases
  • Uses: Erionite is no longer mined or marketed for commercial purposes. Although other natural zeolites have many commercial uses (pet litter, soil conditioners, animal feed, waste-water treatment, gas absorbents, etc.) because of their unique properties, very few data are available specifically for erionite. It reportedly was used in the past as a noble metal-impregnated catalyst in a hydrocarbon-cracking process and was studied for use in fertilizers and to control odors in livestock production. Erionite-rich blocks have been used to build houses in parts of the western U.S., but this was a minor and unintentional use of the mineral. Source: Hazardous Substances Data Bank (HSDB)

How CAS 12510-42-8 is used on this site

CAS 12510-42-8 is the Chemical Abstracts Service identifier used to pin this page to a specific substance. In the current dataset, 1 EU annex record shares this identifier, which helps you cross-check whether the same substance appears under one regulatory context or several.

Use this page when a supplier specification, SDS or raw-material dossier gives you CAS 12510-42-8 and you need to see every linked Annex II–VI record in one place. The entry cards above are the quickest route to concentration limits, warnings, annex placement and product-type conditions.

Frequently asked questions

A substance identified by CAS 12510-42-8 may appear in multiple EU cosmetic regulation annexes when it is subject to different conditions in different contexts. For example, a substance might be restricted under Annex III with specific conditions, and the same CAS might also appear in Annex IV as an approved colorant under separate entry conditions. Each entry must be reviewed individually.

Cross-reference the CAS number against your raw material specification sheets and CoA documents. When a CAS appears in Annex II, verify absence. When it appears in Annex III, verify that concentration limits and product type conditions are met in your formulation. All annex entries sharing this CAS number are listed above.

A CAS number is assigned by the Chemical Abstracts Service (USA) and is globally recognised. An EC number is a European Commission identifier from inventories such as EINECS, ELINCS or the NLP list. Both identifiers may appear in EU cosmetic annex entries. Some substances have both, some have only one, and some older entries may have neither.

The INCI Checker accepts ingredient names, CAS numbers and EC numbers. Check this CAS number directly, then verify the result against supplier specification sheets and every linked annex condition.
