Kupu Whakataki

He whānuitia te whakamahinga o te matū 4-methyl-2-pentanone (methyl isotetramethicone) hei whakarewa i roto i ngā ahumahi matū me te rongoā, te wehenga me te whakaora i ngā hua wehenga karihi, me ngā whakamātautau rangahau pūtaiao. Ko te ihirangi o te 4-methyl-2-pentanone e hokona ana i te mākete he ≤99%, he iti noa te waipiro me ngā matū matū kei roto. Ka whakamahia te 4-methyl-2-pentanone hei whakarewa mō te nitrocellulose, te peita, me ētahi whakarewa me ngā kapia, ā, ka whakamahia hoki hei matū tauhohe mō te hanga o te 2-(1-toluene-3-methylbutyl starch)-1h-indene-1,3(2H)-dione.
