    Abstract: The wax product for treating or setting up a hairstyle or hairdo includes a composition containing at least one wax or wax-like substance, at least one non-volatile liquid hydrophobic oil and at least one volatile or easily volatilized hydrophobic substance that is a liquid or gas at room temperature. Because of the presence of the volatile substance in the composition a soft wax easily worked in the hair is obtained when the composition is applied to the hair. This soft wax hardens on the hair when the volatile ingredients evaporate. When the composition includes a propellant gas a wax with a larger surface area (wax snow) is produced, which is likewise easily worked into the hair and very effectively fixes or sets the hair.

  • Patent number: 6541018
    Abstract: The present invention provides a nanoemulsion, that includes: an oily phase dispersed in an aqueous phase; and at least one glycerol fatty ester surfactant which is solid at a temperature of less than or equal to 45° C.; wherein the 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; and wherein 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. Ideally, the emulsion is 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 the cosmetics and dermatological fields, in particular for moisturizing the skin and/or mucous membranes, as well as for treating the hair, and, in the ophthalmological field, as an eye lotion for treating the eyes.
