Carrier oils/ butters are a very important consideration when embarking on a formulation project, especially when you are making Natural Skincare products. Butters can be defined as solid oils, therefore for the purpose of this post, wherever I mention carrier oils , it would be with the understanding that I am also referring to the butters as well.
These oils are what constitute the emollient components of a Natural skincare formulation and will go a long way to determine how greasy or otherwise a product will be. There are several other factors including the choice of emulsifier, etc.
Therefore the percentage and nature of the oil to be used is important and has to be carefully chosen in order to reach certain defined objectives that a formulator desires.
Certain oils have the ability to clog the pores and lead to breakouts on the skin contrary to the common belief that All oils are bad for the skin.
In some extreme cases, it might become necessary to steer clear of oils completely, however, most times a careful selection of oils is all that might be needed to prevent a break out.
Below is the comedogenic rating of some oils that I have been able to glean from the web.
Comedogenic ratings of 0-1 is suggestive of a non clogging oil which can be used on the face by most people without causing any problems.
Comedogenic ratings of 2-3 might be ideal for facial used for people with dry to very dry skin types
Comedogenic ratings of 3 and above might be best used for other parts of the body except the facial area.
