Preserving skincare products

Preserving skincare products

 

If skincare products have water in them, then they need to be preserved.

Moisturisers, lotions, creams and body butters are all made with differing combinations of water and carrier oils, along with emulsifiers to blend the oil and water.

The above products must be preserved or they will go mouldy within days.

Preservatives are used in differing percentages, which the manufacturer will have given guidance with.

If you are making 100g of cream and the preservative is to be used at 1%, then you need 1g of preservative.

Balms use no water. They are made with some kind of wax, usually beeswax, and carrier oils.
Therefore, balms don’t need a preservative.

They won’t last forever though. All oils eventually go rancid.

If you want your balms to last a few months, especially over hot months, add Vitamin E at 0.5%. This will delay rancidity.

100g of balm = a few drops of Vitamin E.
