Students are expected to
The list of most common ingredients of home-made cosmetics, their purpose, properties, where to obtain them from, where they are used.
Materials and equipment
We offer the following list of the ingredients easily found from trade:
Oils and fats: Cocoa butter/cocoa oleum, coconut oil, olive oil, almond oil, ricinus oil (castor oil), shea butter, grape seed oil, liquid parafine, avocado oil, apricot kernel oil,
Vitamines: E-vitamine, A-vitamine.
Emulsifiers: stearic acid, bees wax.
Essential oils, rose water.
Some essential ingredients can also be found from home, eg. honey, vitamins, essential oils to add the odour, herbs that can be used to make water-based extracts and be used in the recipes instead of (rose) water etc.
Supplies that are needed include electronic weights, (wand) mixer or hand whisk, a cooker or at least hot water that can be used as a waterbath to melt the ingredients. It is convenient to use small bowls made of stain (stainless/enamel-coated). These small bowls can be put into a pot or into a bigger stain bowl to be used in the waterbath to melt the ingredients together and mix them. Empty jars for the cream are also needed.
|Suggestions for use:|
In this part, students will choose, based on their Internet searches, the recipe of a favourite cream (preferrably it should be an emulsion cream), and start to develop their own product. Before the next activity it would be useful four groups to read through the Internet article „How to Market Your Own Cosmetics” (http://www.makingcosmetics.com/How-to-Market-Your-Own-Cosmetics-149.html) getting the necessary knowledge for the following activities.
As a result of this activity, students have to present the list of necessary ingredients and the plan and rationale of the following activities to the teacher.
