EPA is providing a 90-day comment period during which interested persons may provide comments on the proposed designations for the following: 1. 1-Butanol, 3-methoxy-, 1-acetate; 2. D-gluco-Heptonic acid, sodium salt (1:1), (2.xi.); 3. D-Gluconic acid; 4. D-Gluconic acid, calcium salt (2:1); 5. D-Gluconic acid, .delta.-lactone; 6. D-Gluconic acid, potassium salt (1:1); 7. D-Gluconic acid, sodium salt (1:1); 8. Decanedioic acid, 1,10-dibutyl ester; 9. 1-Docosanol; 10. 1-Eicosanol; 11. 1,2-Hexanediol; 12. 1-Octadecanol; 13. Propanol, [2-(2-butoxymethylethoxy)methylethoxy]-; 14. Propanedioic acid, 1,3-diethyl ester; 15. Propanedioic acid, 1,3-dimethyl ester; 16. Propanol, 1(or 2)-(2-methoxymethylethoxy)-, acetate; 17. Propanol, [(1-methyl-1,2-ethanediyl)bis(oxy)]bis-; 18. 2-Propanol, 1,1’-oxybis-; 19. Propanol, oxybis-; and 20. Tetracosane, 2,6,10,15,19,23-hexamethyl-.
