Abstract

MUJICA, Viky et al. FORMULATION OF A COSMETIC PRODUCT WITH ANTI-WRINKLE PROPERTIES BASED ON CASHEW SEED OIL (Anacardium Occidentale L). Rev. Fac. Ing. UCV [online]. 2010, vol.25, n.2, pp.119-131. ISSN 0798-4065.

This study focuses on the pilot scale extraction, characterization and purification of cashew oil by using Sohxlet equipment. An experimental design is used in the extraction in order to set better operative conditions. Variable interaction and its influence on the process are analyzed. From oil proximal analysis, the following results are obtained: moisture 6.744%, ash 2.842%, calcium 0.0267%, fiber 1.768%, protein 19.2996%, free fat 43.5335%; these results are adjusted to the expected. A 38.02% yield was obtained by using 1.5 kg of seeds and 8.0 L of solvent (n-hexane). Seed batch and solvent volume are important variables in the extraction process, there being no interaction between them. From oil characterization properties were defined: saponification index 181.8 mg KOH/g, iodine 71.4 cg I/g, acidity 1.23 mg NaOH/g, peroxide 1.8 meq O2/g, refraction index 1.4721, pH 5.5, relative density 0.89844, dynamic viscosity 71.6 cP, color 2.5 red/25 yellow. Fatty acid profile allows us to define this oil as linoleic. The values obtained for the cosmetic product with regards to pH, relative density, dynamic viscosity a 40ºC and 10 rpm, acidity index are: 7,50; 1,2468 g/mL; 21.000 cP y 1,85 mg NaOH/g respectively. The study of the market indicates acceptance of the cosmetic product in aspect, smell and adsorption as good and very good. A 78,4% attenuation in the wrinkles was obtained
