– emulsions of oil in water
– emulsions of water in oil
– gels on water basis
Naturally, oil and water do not mix. Therefore emulsifiers are added. Emulsifiers act like surfactants; their tails dissolve in the oil-part and their charged heads in the water-part. This way micelles are formed which do dissolve in oil resp. water.
One of the oldest and known oils, applied in skin care products, is vaseline. Not to make it too easy the INCI name for vaseline is ‘petrolatum’. Vaseline does not absorb into skin but stays on top to form a protective layer. Around 1870 it was discovered that burn- and other skin wounds healed faster when covered by a layer of vaseline. By this coverage vaseline thus also helps to avoid dehydration of the skin. Vaseline becomes liquid between 40 and 60 °C. As our body temperature lies around 37,5 °C, the vaseline on our skin remains firm but smooth enough to keep forming a closed, continuous layer.
Except water, oil and emulsifiers all kinds of active ingredients are added to cosmetics, such as Aloë Vera, Jojoba, Tee-tree, even snail slime, you name it. The most important criteria for these additives is the fashionable trend of the moment.
Normally the formation of a stable emulsion requires time, several process steps and heat. Mixtures of oil, water and emulsifiers are slowly heated for on average 5 hours. Britecream one-step processable oils at room temperature do not show these disadvantages. The producer of Britecream has developed types which create an emulsion in one step without heating. Emulsions which can be processed at room temperature were already on the market. They make us of mineral powders which are added as thickeners. The disadvantages are:
In short, you need the Britecream bases of Sirius International.
Because you’re worth it.
