High peak exposures do not occur during the manufacturing or use. This distribution suggests that the study population were towards the more sensitive end of the overall population in terms of their response to respiratory irritants and, as such, could be regarded as an adequate representation of the general population in terms of their response to sodium hydroxide. irritating effects observed in humans after accidental exposure were fully reversible. Safety Information. Also . endstream endobj startxref Additional Information: Potassium carbonate will dissolve in water forming liquid potassium carbonate, which is an irritating and corrosive material. 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. irritating effects observed in humans after accidental exposure were fully reversible. ��4 �(�4;�{��iې�o��;dw�!�c���?����۾�h���������2�g�䡫�~���s �����>ۭ>?O31bv6l�!�W)���tm�^�է�R�o0�q˕o0� �%Cm|{�.$�:�C���IZ�?�X�M,�`�v��L�h2�ͪ������ 7��� endstream endobj 166 0 obj <>/Metadata 4 0 R/Outlines 8 0 R/PageLayout/OneColumn/Pages 163 0 R/StructTreeRoot 11 0 R/Type/Catalog>> endobj 167 0 obj <>/ExtGState<>/Font<>/XObject<>>>/Rotate 0/StructParents 0/Type/Page>> endobj 168 0 obj <>stream Me -#��n›���>��HA|G��pܮc���M����8�5��遹�8C��2�>�?�~$�]�G� ��m�22� �1'd��N�E�w�i�2H

Liquid potassium carbonate is corrosive to aluminum. Further on, it is highly unlikely that the general population will be exposed to potassium carbonate by inhalation. Based upon these considerations, it is concluded that the dose of 80 mg/cm, Exposure to sodium hydroxide mist had been assessed on a semi-quantitative basis and the exposed subjects had been assigned to one of three exposure groups: low (<0.05 mg/m, This data suggests that the NOEL for respiratory irritation due to exposure to sodium hydroxide mist in a large sample of subjects from three factories was 1.0 mg/m, In addition, it is noted that in many EU countries, the OEL (8-hour TWA) for sodium hydroxide is 2.0 mg/m. ��5�00$�0�� ��v�^��`f��Y�����k��\V��E��;!2ri&f�C`��Sn5s�R�*&� k�� Potassium carbonate will dissociate into its constituent ions and will not be systemically available in the body. Symbol GHS07. Potassium carbonate is found mostly in glass and various types of soap, including hand soap or dishwasher detergent. The solution crystallizes to form potash hydrate, which can further be heated above 200°C to produce the anhydrous salt. It is industrially prepared by reacting potassium hydroxide and carbon dioxide. 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.

CONTACT WITH SKIN When in contact with skin, potassium carbonate causes irritation, particularly after prolonged exposure.
