Definitions

  • This application relates to the technical field of cosmetics.
  • the invention relates to a composition for lipstick comprising a volatile mixture of alkanes.
  • alkane is a saturated hydrocarbon consisting solely of carbon and hydrogen atoms linked together by single covalent bonds, the general formula of which is CnH2n+2.
  • a “linear alkane” is an alkane in which each carbon atom is bonded to a maximum of two carbon atoms.
  • branched alkane is used to denote an alkane in which certain carbon atoms are bonded to three or even four carbon atoms.
  • Cx alkane refers to an alkane consisting of x carbon atoms, said alkane possibly being linear or branched.
  • dodecane is a C12 alkane.
  • volatile mixture of alkanes refers to a mixture of alkanes having a flash point of less than or equal to 95° C. measured according to the ATSM D93 standard.
  • volatile mixture of alkanes means a mixture of alkanes having a flash point of less than or equal to 55° C. measured according to the ATSM D93 standard.
  • flash point The flash point measured according to the ASTM D93 standard is called “flash point”.
  • the unit of the flash point measured according to the ASTM D93 standard is the degree Celsius (°C). It can also be an average of values, each of the values being obtained by means of a measurement according to standard ASTM D93.
  • mass percentage refers to the ratio of the mass of a first compound relative to the total mass of a mixture of compounds or composition, reduced to a percentage. For example, if 10 grams of a compound y are present in a mixture z having a total mass of 100 grams, then the mass percentage of y in z is 10%.
  • a compound or an organic composition in which the organic carbon present in the compound or composition is 100% of plant origin is described as "biobased" by radiocarbon analysis according to one of the following standards. ASTM D6866, EN 16640 or EN 16785-1.
  • naturalness index of an organic composition refers to the percentage of organic carbon of plant origin ( 14 C) determined by an analysis radiocarbon according to one of the following standards ASTM D6866, EN 16640 or EN 16785-1.
  • the OECD 301F method makes it possible to assess the biodegradability of a substance by a manometric respirometry test.
  • isododecane can represent up to 60% by mass percentage of the composition of these cosmetic formulas.
  • isododecane is a key component because it allows obtaining long-lasting performance, absence of transfer and resistance to water, while maintaining optimal comfort. This market was developed from this essential ingredient, isododecane, derived from petrochemicals
  • a first approach consists in developing a method for producing isododecane that does not make use of petroleum raw materials.
  • the isobutene gas obtained is then converted into isododecane by an oligomerization reaction in the solvent phase followed by a hydrogenation step according to patent application WO2021228824.
  • This excipient is a volatile mixture of alkanes as previously defined.
  • this volatile mixture of alkanes is obtained from fatty alcohols by a Guerbet alcohol reaction followed by a dehydration and hydrogenation reaction.
