To derive a DNEL long-term exposure - local effects inhalation for the general population for potassium carbonate, a read-across to sodium hydroxide, which also solely acts via its alkalinity is made. Potassium carbonate . LOW HAZARD. Based upon these considerations, no DNEL for local dermal effects in workers is derived. Slight. It is industrially prepared by reacting potassium hydroxide and carbon dioxide.

Liquid potassium carbonate is corrosive to aluminum. Based on the previous discussion, the OEL of potassium carbonate should be higher than 5 mg/m. Potassium carbonate is found mostly in glass and various types of soap, including hand soap or dishwasher detergent. In conclusion, the DNEL for potassium carbonate for long-term inhalation, consumers is 10.0 mg/m³. Potassium carbonate will dissociate into its constituent ions and will not be systemically available in the body. POTASSIUM CARBONATE (ANHYDROUS ALL GRADES) SDS No. 0 the case for potassium carbonate.

Please upgrade your Internet Explorer to a newer version. calcium hydroxide is expected to be distinct higher than the activity of potassium carbonate. Additional Information: Potassium carbonate will dissolve in water forming liquid potassium carbonate, which is an irritating and corrosive material. 165 0 obj <> endobj endstream endobj startxref |�ɀs���*�'��슠�5� Target Organs: Respiratory system, eyes, skin. Potassium carbonate may be used as a base in the synthesis of phytochemical-based oryzanol modified polystyrene from 4-chloromethylstyrene and γ-oryzanol in order to study their liquid crystal (LC) orientation property. The data on sodium hydroxide have been evaluated within an EU Risk Assessment carried out in accordance with Council Regulation (EEC) 793/93. the DNEL is dispensable due to exposure considerations. There is no indication that this chemical may be carcinogenic or mutagenic, but it can be toxic if in contact with skin and eyes, swallowed or inhaled. �T��.�K�B�+�d#?

The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). ��إ'^��6Z��uL2�Ͻ�3�=�7�*_�[.$q�B��T�c��)�(T��J��I�Z�(YG�����}\ �'�F�k�#T�o�IJ^Eo�7�. Also . No further modification is therefore required to the NOAEL to take account of potential differences in the duration of exposure of the general population. Sodium sesquicarbonate . Further on, it is highly unlikely that the general population will be dermally exposed to potassium carbonate. They liberate carbon dioxide on gentle heating (or with acids). Potassium carbonate is found mostly in glass and various types of soap, including hand soap or dishwasher detergent. h��[[o۸�+zlQ����8�ݴ�:=�6胛h[�$v`��Ϳ?3#��d��h� �!9���|�,�(X!�,��D�A�.��Km!���Z ���Xx�0�C���E��� �y��U���H��� �ۂ 8p���P��I�Bq�!�%=T�P���LC�BZi�S�B������u\�P!����X.� U%�*Qi�Ç�s`�n����4��\A�B���P�r�8���Oz 99�R��HJb�vY�ǣyu]p� V���`9b��[yt:,��̫���|3�ݎn��Q���ʷ�B��wg/�G�b��*�g�����*�����?����hQ�W#j7������{��m�og��l��i~��1]NO���)��W���,1+O����L��f�u^���t�8>��sɈ�E���g*z1���?��~��9oF�U�������guͳs*.f���[�)d]��(��t1�_M��T+��������4aU�w6�[Lg��0��1��c��^q�� �t�ה^I��ӓ���ӓ��]g���b �J,u+/.��/�a�?^�Lp�j��_�`�xN~;z>��^Ú'�^�α?V�O?L�P��Y��&��P��'�q�e4F���HfV��@��"t\�5�f �e6nڍl�ͧ���g�����ӛ�-�c�����x�M���e@��o@\�f@��K�]m@\�P�z+F{#RF�܈r���&7L���P,�� #8��G7ś�l6���r݉]s��l,���� ��M��'�!6���ߡA�Ƌ��h2����|1�6��];��G���z9����E?�^|�_�~�+���B${�V��vi+�$�� The solution crystallizes to form potash hydrate, which can further be heated above 200°C to produce the anhydrous salt. irritating effects observed in humans after accidental exposure were fully reversible.

This read-across is a conservative approach, since the activity of sodium hydroxide is expected to be higher than the activity of potassium carbonate because of the distinct higher alkalinity of sodium hydroxide.
