8. Amphoteric surfactants (amino acids, betaines, sulpho-betaines).

9. Nonionics surfactants (oxyethylenates and polyhydroxycompounds).

10. Raw materials for production of detergents (zeolites, silicates, peroxo-compounds, enzymes, etc).

11. Powder detergents (washing powders, production technology, evaluation).

12. Liquid detergents (washing detergents, conditioning agents, evaluation).

13. Analytics and biological decomposability surfactants and detergents.

14. Correct production practice. Legislation. Datasheet and safety of product.
