Course Description:
The course will begin with an introduction to skin, its physiology, primary function and major
constituents. Following the introduction the course will consider the fundamental characteristics,
performance, ingredients and technologies used in cosmetic formulations such as: emulsifiers,
rheology modifiers and thickeners, moisturizers, humectants, emollients, preservatives, vitamins,
antioxidants, AHA and BHA, skin protectants, skin lighteners, sunscreens. Topics covered in the
course will also include emulsion technology, types of emulsions, stabilization of emulsions and
preparation methods for emulsions. Fundamental categories of skin care and OTC products
currently on the market will also be discussed; these will include body & facial moisturizers, anti-
aging technologies, anti-acne products, skin lighteners, skin protectants, sunscreens, self-
tanners, bath and shower products, shaving products, spa products. Each class will also
address formulation approaches and functional methods of developing specific cosmetic skin
care products.
Objective:
Upon successful completion of this course, students will be familiar with the basic types of skin
care raw materials used in the cosmetic industry, emulsion technologies, categories of cosmetic
and OTC skin care products as well as understand how to formulate cosmetic skin care
products.

Oral Presentations Requirements
Oral presentations - Due on April 28 and May 5, 2009
Each student has to prepare an oral presentation (hard-copy included) due to me on April 28 and May 5,
2009. The presentation has to be 10 minutes in length and in PowerPoint format.
Topic
Select one of your preferred ingredients that is used in the skincare industry (e.g. a moisturizer, an

and prepare a presentation (in PowerPoint) covering the selected topic.
Points to be covered/ included in presentation:
Title of the presentation
Introduction with outline
INCI name of the ingredient
Chemical classification
Molecular weight
Chemical structure
Physical chemical properties
Specifications: purity, solids, pH (if applicable)
Role in skincare applications
Scientifically justify the reason(s) of selecting your ingredient
With your preferred ingredient develop a formulation including:
Product name
Product type (gel, emulsion)
Weight percentages
Phase sequencing
Ingredients trade name and INCI names with suppliers (if available)
Functions of all other ingredients used in your formula
Manufacturing procedure
Ingredient list
Estimate product's appearance and rheology
Targeted skin type
