The present invention is directed to an emulsion base for formulating cosmetic and dermatological compositions. The emulsion base has particular surfactant and/or emulsifier ratios such that a wide range of compositions with varying forms and additional components can be formulated without changing the ratio or amount of the primary and/or co surfactant/emulsifier in the emulsion base or the amount of the emulsion base in the final composition. The emulsion base can be used in a system of formulating cosmetic and dermatological compositions.

Why it's free to use
- Filed May 28, 2004 and granted August 28, 2012. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended May 28, 2024.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by May 28, 2026.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
