2. Be able to recognize the function of each excipient of a given cosmetic product and the possible interactions among them. Be capable of formulating the main categories of cosmetic products (solutions, creams, lotions, detergents) (applying knowledge and understanding).
3. Be able to communicate the results of scientific studies also to a non-expert audience. Be able to write a formal document, neat, understandable and appropriate for the professional context. Be able to produce a written document morphologically, syntactically and grammatically correct (communication skills).
4. Be able to evaluate the quality of a cosmetic product as a function of its composition and the instruction for use indicated (making judgements).
Be able to connect the different subject studied among them and with the basic disciplines. Have the capability of continuous education, through the scientific publications in the field of pharmaceutical technology (learning skills).
Module 2
The purpose of this course is to acquire a deep-rooted knowledge of the fundamental principles of the controlled drug delivery and innovative formulations (both marketed and in-development) and to develop the ability to apply these principles to different kind of formulations and administration route. A further aim of the course is to provide the students the tools for the elaboration of the information given so as to integrate them into their knowledge. In particular at the end of the course the student shall:
-have aquired specific knowledge on mechanisms, materials, processes and formulations
-be able to compare the innovative formulations with the traditional ones
-be able to highlight, for every innovative formulation/administration route, potentialities, limits and impact on patient therapy
-be able to present (orally or in writing) the topics studied in a clear way and using a correct technical language
Prerequisites
Pharmaceutical technology is a pre-requisite.

Textbooks for consultation (available in the library of the Dipartimento di Scienze degli Alimenti e del Farmaco):
• G. Proserpio, Le basi della cosmetologia, Ed. SEPEM, Milano. (in Italian)
• I. Bonadeo, Prodotti Cosmetici, cosmetologia e tecnologia cosmetiche, Ed. Librería Cortina (Milano) (in Italian)
Module 2
Textbook: Principi di tecnologie farmaceutiche, P. Colombo, P.L. Catellani, A. Gazzaniga, E. Menegatti, E. Vidale, Casa Editrice Ambrosiana Ed. 2004
Since some topics are not present in the book, specific texts (available at the library of the Department of Pharmacy) will be suggested.
The teachers make available, on a weekly basis, copies of the slides on Elly portal (in Italian)
Teaching methods
The course includes lessons, using slide projections, that will be available online for students on Elly. Slides are complementary didactic material.
The teacher will recall continuously to the use of the appropriate technical language, will use everyday life examples, will underline connections among different parts of the course and will promote active student participation. 4 hours will be dedicated to exercises and mock examinations.
Assessment methods and criteria
The summative evaluation of the knowledge acquired is made through a written exam, made of two partials relative to the two modules. The student should, then, after online enrollment:
a) pass a written exam during the official dates established by the Dipartimento di Scienze degli Alimenti e del Farmaco (Module of cosmetic products, weight 50% of the overall grade);
b) pass a written exam during the official dates established by the Dipartimento di Scienze degli Alimenti e del Farmaco (Module of innovative pharmaceutical formulations, weight 50% of the overall grade);
Each written exam, duration 1 hour, consists of 6 open answer questions and 12 multiple choice questions.
The student should demonstrate to have understood, and to be able to apply, the fundamental concepts of each subject studied. In particular, the evaluation of each module, expressed in thirtieths, will be made on the basis of the following criteria:
1. knowledge and comprehension (theoretical and practical) capability of the subjects studied;
2. Ability to make judgements and to connect the different subject studied among them;
3. communication skills and appropriate use of the technical language;
4. ability to learn and to elaborate the subjects studied.
The results of the exam are published on the portal ESSE3 (https://unipr.esse3.cineca.it/Home.do) within one week of the date of the exam. Students can see the exam, by appointment with the teacher.
A fac-simile of the examen is available to the students on the Elly portal.
