87836 - Cosmetics Technology And Industrial Production

Learning outcomes

At the end of the course the student has achieved theoretical knowledge on the industrial preparative technologies, laboratory controls and stability of the different cosmetic forms, in compliance with current European regulations and according to the Good Manufacturing Practices. The student has the theoretical and practical knowledge necessary to address formulation issues related to the main cosmetic forms.

- Notes and slides from lectures

Teaching methods

The course is based both on classroom lectures and on laboratory practice.

Classroom teaching will address systematic learning of the procedures and industrial implants needed for the production of raw materials and semifinished or finished cosmetic formulations. The teacher will stimulate critical discussion and active participation of students. Lab work will be both individual and based on collaborative work by small groups of students, under the supervision of the teacher.

The course also includes guided visits to industrial production pants.

Assessment methods

Learning will be assessed by a final oral examination on the course content. The final mark will also take into account the attendance and active participation of students in laboratory work. Learning from laboratory experience will be assessed through a written final report that each student will be asked to prepare at the end of the course.

Teaching tools

Copy of the slides used during the lectures and of lab manuals will be provided via the portal Insegnamenti On Line (https://iol.unibo.it/). The students will be illustrated professional free-access databases available on-line for individual complementary learning.
