Team Sirius wishes very much strength to all those who fight in her or his way against the Covid-19 virus and its consequences.

–      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.

Well known emulsifiers on natural basis are stearates, palmitates, glutamates. The same surfactants as in our Cocobrite and Britens APG products.

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.

The Sirius Effect
Back to science; in our Britecream series you find many kinds of oil bases for cosmetics. All Britecream types are readily bio-degradable according to OECD.

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:

  • after 4 hours at 50 °C such emulsions loose their viscosity; also after cooling down again they will not obtain their original thickness 50 °C is a temperature not uncommon in trucks during summer time, so not unusual during transport of cosmetics
  • at min10 °C such emulsions do not remain spreadible; they become sticky.


In short, you need the Britecream bases of Sirius International.
Because you’re worth it.
