Objectives

Students in this course unit will be able to:
• Understand and integrate chemistry concepts in product design by analysis of case studies.
• Assessment of current procedures used in product design, comprising 4 stages: needs identification, ideas, selection and production.

Program

1. Global concepts of product chemistry applied to product engineering.
1.1. Introduction.
1.2. Historical overview – chemical products (commodities), fine chemicals (specialties) and added value products.
1.3. Heuristic approach to product design: needs identification, ideas, selection and production.
1.4. Definition of product functions – case studies.
2. Fine chemistry and technology of inorganic products – alcoholates, inorganic salts, Lewis acids, hydroxylamine and derivatives, sulphur compounds, synthetic pigments.
2.1. Inorganic materials for photovoltaic devices: semiconductors and natural/synthetic dyes
3. Chemistry and technology of cosmetics and hygiene products.
3.1. Raw materials and main reactions of surfactant preparation.
3.2. Functional additives for hygiene products – thickening agents, foam stabilizers, conditioning and sequestering agents.
3.3. Oils and waxes: moistening agents and emulsifiers.
3.4. Hair care products: interaction between chemical structure and hair physiology; dermatologic products: interaction with skin; chemical formulation and chemical and microbiological stability tests; Dyeing products: colour cosmetics; nail chemistry and varnish technology; Dental hygiene products: interaction with dental chemical structure and saliva.
3.5. Global concepts of industrial chemical processes – classification of the production process; block and process flow diagrams, symbology of unit operations and processes in chemical industry. Case studies.
4. Perfumes chemistry and technology – assessment of the perception to fragrances; natural and synthetic fragrances; extraction technology of natural aromas; chemical compounds of perfumes; computer-aided design and combinatorial chemistry.
5. Chemistry and technology of new generation phytosanitary products.
5.1. Classification according to its chemical structure and mode of application.
5.2. Toxicity mechanisms.
5.3. Pesticides versus natural products with similar effect.
5.4. Synthesis of pesticides and agreement with REACH legislation.

Teaching methods and learning activities

Classes will be based on theoretical lectures complemented by case study analysis; Students will be asked to develop an individual project and to present it and discuss it throughout the semester; 2 seminars are also foreseen in the course unit.

Eligibility for exams

To be admitted to exams the student must reach a passing grade (≥10 out of 20) both in the Project and the Report. Additionally, the student must attend the seminars (minimum of 1 presence out of 2).

Calculation formula of final grade

FG = 0.05 AP + 0.30 PR + 0.30 REP + 0.35 EX
where:
AP is set according to the student’s attendance to classes, seminars, as well as punctuality (up to 10 minutes after classes start); (1 absence, AP=20; 2 absences, AP=10; >3 absences, AP=0)
PR is the average grade of 3 presentations given by each group throughout the semester in specific stages of the project development process (50% presentation and answers to specific questions + 50% slides content).
REP is the classification given to the final report of the project developed throughout the semester, within the group, which is due on December 21st, 2012.
EX is the classification of the final written exam, which will focus the topics addressed in classes (30%), and the classification of the individual answers to questions related to the topics addressed in seminars and the content of the presentations given by each working group (5%). Students will be asked to answer these questions and deliver them in the class following the oral presentations/seminars.

Those students not reaching a passing grade will be given the opportunity to make an additional written exam. Students must reach Project (PR) and Report (REP) final classifications over 10 (out of 20) and the final grade of the course unit, FG1, will be estimated according to:

FG1 = 0.05 AS + 0.30 PR + 0.30 REP + 0.35 EX

To complete this course unit, students must meet a minimal final grade, FG1, of 10 (out of 20).

Examinations or Special Assignments

Not applicable.

Special assessment (TE, DA, ...)

According to the current regulation, and if the student meets the Project and Report evaluation criteria, the final grade of the course unit, FG2, will be estimated according to:

FG2 = 0.05 AS + 0.30 PR + 0.30 REP + 0.35 EX

To complete this course unit, students must meet a minimal final grade, FG2, of 10 (out of 20).

Classification improvement

Students wishing to improve their final grades must perform an extra Project (REP), similar to that developed during the semester, which is due at the end of the 1st semester evaluation period. In addition, an extra written exam is required. The final grade of the course unit, FG3, will be estimated according to:

FG3 = FG2 = 0.05 AS + 0.30 PR + 0.30 REP + 0.35 EX

To complete this course unit, students must meet a minimal final grade, FG3, of 10 (out of 20).
