The present invention provides a nanoemulsion, that includes:an oily phase dispersed in an aqueous phase; andat least one surfactant that is solid at a temperature of less than or equal to 45° C. and which is selected from the group including ethoxylated fatty ethers and ethoxylated fatty esters, and mixtures thereof; whereinthe oily phase includes oil globules having a number-average size of less than 100 nm;wherein the oily phase includes at least one oil having a molecular weight of greater than 400; andwherein a weight ratio of the oily phase to the surfactant ranges from 2 to 10. The invention also provides a process for making the nanoemulsion, and methods for its use. The emulsion is ideally transparent and stable on storage. It can ideally contain large amounts of oil while retaining good transparency and good cosmetic properties. The nanoemulsion is particularly useful in compositions, including topical, pharmaceutical, cosmetic, opthalmic, ophthalmologic. The composition is also particularly useful in applications to the skin, hair, scalp, mucous membranes, and eyes. |
