Household Chemistry 0600-S2-ChK-SP/W-ChG

Lectures:
During the lecture, the main groups of raw materials included in household chemical preparations will be discussed: surfactants, fillers, acidic and alkaline additives, solvents, bleaches, enzymes, thickeners, agents preventing the redeposition of dirt, etc., and the advisability of their use to obtain a given group of products. Various types of modern household chemicals products will be presented: agents for manual and machine washing dishes, for washing and softening fabrics, disinfecting, cleaning and maintaining various types of surfaces, removing greasy and mineral dirt, cleaning and maintaining floors, for cleaning windows, and car cosmetics. The basic principles of creating recipes for specific types of products will also be discussed. The main directions of development of the household chemicals industry will be presented, with particular emphasis on ecological aspects, both in the production and use of products.

Exercises:
Analysis of groups of household chemicals products available on the market. Familiarization with methods of working on innovative solutions - elements of the Design Thinking and TRIZ methods. Designing a new household chemicals product from "idea to product".

Lab:
Familiarization with methods of testing and assessing the quality of selected household chemicals products.
1. Determination of the content of anionic surfactants by two-phase titration.
2. Determination of emulsification capacity.
3. Determination of active oxygen content in washing agents.
4. Determination of foaming properties.
5. Assessment of the washing capacity of selected commercial preparations.
6. Assessment of the cleaning properties of hand dishwashing agents.
