The present disclosure relates to a method of preparing a fatty acid ethyl ester, comprising: preparing a vegetable lipid; performing transesterification by mixing the vegetable lipid, a first fatty acid ethyl ester, and lipase in a reactor; removing the triglycerides and diglycerides present in the reactor; and separating a second fatty acid ethyl ester via rectification from the reactor.
According to the present invention there is provided a container comprising a flexible wall and a dispensing head, wherein the dispensing head is not detachable from the rest of the container during normal use; wherein the dispensing head comprises a dispensing orifice; wherein the smallest cross-sectional area of passage through the dispensing orifice is between 0.2 mm2 and 2.0 mm2 and wherein the container contains a fluid skin colour cosmetic composition having a viscosity of at least 10,000 cps measured at 23 °C and comprises at least 20% of one or more pigments.
The present invention also provides a method of converting a skincare composition into a colour cosmetic composition comprising dispensing one to five drop(s) from the container as defined above onto an amount of skincare composition suitable for application to one or more of the skin regions selected from the list consisting of (a) one or more specific parts of the face; (b) the face as a whole; (c) the neck; and (d) the décolletage.
The present invention also provides a method of altering the colour of a colour cosmetic composition comprising dispensing one to five drop(s) from the container defined above onto an amount of colour cosmetic composition suitable for application to one or more of the skin regions selected from the list consisting of (a) one or more specific parts of the face; (b) the face as a whole; (c) the neck; and (d) the décolletage.

[EN] Methods and apparatus for analyzing a sample, such as a biodiesel fuel sample, are disclosed. The method comprises the steps of determining individual amounts (i) mono-, (ii) di- and (iii) tri-acylglycerols in the biodiesel fuel sample using a liquid chromatography device in combination with a detector and, based on the individual amounts of respective acylglcycerols in the sample, providing value for one or more sample parameters. [FR] L'invention concerne des procédés et un appareil pour l'analyse d'un échantillon, tel qu'un échantillon de carburant biodiesel. Le procédé comprend les étapes consistant à déterminer des quantités individuelles de (i) mono, (ii) di et (iii) tri-acylglycérols dans l'échantillon de carburant biodiesel en utilisant un dispositif de chromatographie en phase liquide en combinaison avec un détecteur et, à partir des quantités individuelles des acylglycérols respectifs de l'échantillon, fournir une valeur pour un ou plusieurs paramètres d'échantillon.
