Students in this course unit will be able to:
• Understand and integrate chemistry concepts in product design by analysis of case studies (goods for human consumption).
• Assessment of current procedures used in product design, comprising 4 stages: needs identification, ideas, selection and production.
At the end of this course students should be able to:
• Identify the main principles of Product Engineering
• Establish relationships between chemical composition and specifications of a product;
• Suggest the chemical composition of a product, according to the specifications and the surface where it acts
• Propose a technological process for the production of a specified product
1. INTRODUCTION TO PRODUCT ENGINEERING - Historical evolution. Commodities versus Specialties. Product design - Needs identification, Ideas, Selection of ideas, Production. Protection of intellectual property - patents. General concepts of industrial chemical processes - classification of production processes, types of flow diagrams, symbolism of process and unit operations in the chemical industry.
2. SPECIALTIES – Chemicals commonly used in industry and most relevant specialties. The importance of the inorganic chemicals. Particular case of chemical colour (pigments and dyes). The perception of colour. Dyes vs. pigments – definition, classification, nomenclature and examples.
3. PAINTS AND VARNISHES - Basic concepts. Paint and varnishes definition. Main constituents of a paint. Colour formulation in the industry. General characteristics of a paint. Manufacture process.
4. PESTICIDES - Definitions. Global market. Risks of use and toxicology. History of pesticides. Classification of pesticides. Design of new pesticides. Pesticide formulations and application. Labelling and legislation.
5. COSMETICS AND HYGIENE PRODUCTS - chemistry and technology. Raw materials and functional additives for hygiene products: surfactants/emulsifiers, conditioning agents, thickening agents, foam stabilizers, chelating agents, humectants, antioxidants, pH regulators, fragrances, etc.
Dermatological, hair care, make-up and dental hygiene products.
6. PERFUMES - chemistry and technology. Assessment of the perception to fragrances. Natural and synthetic fragrances. Extraction technology of natural aromas. Chemical compounds of perfumes.
Classes will be based on theoretical lectures complemented by case study analysis; Students will be asked to develop a group project on “Chemistry and Technology of…” and to present it in 2 oral presentations and discuss it throughout the semester; Seminars, mini-lectures or field trips are also foreseen in the course unit.

To be admitted to exams the student must reach a passing grade (≥10 out of 20) in the Mini-Tests, Project presentation and in the Report. Additionally, the student must attend 2/3 external activities - the seminars, mini-lectures or field trips.
FG = 0.40 REP + 0.60 MT
where:
FG is the final grade
REP is the average classification given to the 2 presentations (15%) and to the final report of the project developed throughout the semester (25%).
MT is the weighted average classification of the 3 mini-tests with 45 min of duration and performed throughout the semester, which will focus on the topics addressed in classes and seminars/mini-lectures/field trips (7/20):
MT = 0.30 MT1 + 0.30 MT2 + 0.40 MT3
Those students who do not achieve a passing grade or do not have the minimum grade in the mini-tests will have the opportunity to make an additional written exam. The final grade, FG1, will be estimated according to:
FG1 = 0.40 REP + 0.60 EX
where:
EX is the classification of the new written exam.
To complete this course unit, students must obtain a minimum final grade, FG of 10 (out of 20).
Not applicable.
Not applicable.
Students wishing to improve their final grades must perform an extra Project (PRO), similar to that developed during the semester, which must be delivered at the end of the 1st semester evaluation period. In addition, an extra written exam is required. The final grade of the course unit, FG2, will be estimated according to:
FG2 = 0.40 PRO + 0.60 EX
To complete this course unit, students must meet a minimum final grade, FG2, of 10 (out of 20).
