This invention relates to processes for making bio-based renewable oils from non-food biomass sources. Such renewable oils are used for cosmetics formulations. More specifically, disclosed are processes of preparation of furan-based compounds of the formula: (R1-A)a-CH(R2)-CH2-CH(R3)(A-R1)bwherein: a and b are independently 1 or 2 and 0 or 1; A is: independently an unsaturated, a partially hydrogenated, or a fully hydrogenated saturated fur an ring; -(CH2)4-; a saturated fur an ring-opened moiety containing a hydroxyl or a ketonic group: -CH2-CH2-CH2-CH2- OH or -CH2-CH2-CH2-CH=O; or a partially saturated furan-ring opened moiety containing a hydroxyl or a ketonic group: -CH2-CH2- CH=CH-OH or -CH2-CH=CH-CH=O where the position of the double bond is anywhere within the chain; R1, R2, and R3are: independently selected from H, a furan ring, a tetrahydrofuran ring and alky1 groups having carbon atoms of 1 to 18; and the total carbon content of the compound is from 10 to 40.
