Abstract
Disclosed herein are bio-based compositions comprising branched aromatic compounds and/or branched cycloaliphatic compounds, and methods of their preparation from lignin-derived monomers, and their use as base oils in lubricant compositions, personal care compositions, and pharmaceutical compositions.
Claims23
A bio-based composition comprising a branched aromatic compound having one of the following structures:
- wherein R is an alkyl group having 1 to 20 carbon atoms, wherein the alkyl group is a linear, a branched, or a cycloalkyl group, and wherein R1 and R2 are independently selected from hydrogen and a methoxy group.
A bio-based composition comprising a branched cycloaliphatic compound having one of the following structures:
- and isomers thereof, and
- wherein R is an alkyl group having 1 to 20 carbon atoms, and wherein the alkyl group is a linear, a branched, or a cycloalkyl group.
A bio-based lubricant composition comprising:
- (i) a branched aromatic compound having one of the following structures:
- and optionally an aliphatic enal compound having the following structure:
- or
- (ii) a branched cycloaliphatic compound having one of the following structures:
- and isomers thereof, and
- and optionally a branched aliphatic compound having the following structure:
- and isomers thereof,
- wherein R is an alkyl group having 1 to 20 carbon atoms, wherein the alkyl group is a linear, a branched, or a cycloalkyl group, wherein R1 and R2 are independently selected from hydrogen and methoxy group, and wherein each R3 is an alkyl group having 0 to 19 carbon atoms;
- and
- (ii) an effective amount of one or more additives.
(canceled)
A method comprising carrying out hydroxyalkylation/alkylation of a lignin-derived monomer containing a phenolic hydroxyl group and an aldehyde (RCHO) in the presence of a hyrdoxyalkylation/alkylation acidic catalyst to form a bio-based branched aromatic compound having one of the following structures:
- and optionally a branched aliphatic enal compound having the following structure:
- wherein R is an alkyl group having 1 to 20 carbon atoms, wherein the alkyl group is a linear, a branched, or a cycloalkyl group, wherein R1 and R2 are independently selected from hydrogen and a methoxy group, and wherein each R3 is an alkyl group having 0 to 19 carbon atoms.
(canceled)
A personal care composition comprising:
- a) a base oil comprising one or more of the following:
- (i) a branched aromatic compound having one of the following structures:
- and optionally an aliphatic enal compound having the following structure:
- or
- (ii) a branched cycloaliphatic compound having one of the following structures:
- and isomers thereof, and
- and optionally a branched aliphatic compound having the following structure:
- and isomers thereof,
- wherein R is an alkyl group having 1 to 20 carbon atoms, wherein the alkyl group is a linear, a branched, or a cycloalkyl group, wherein R1 and R2 are independently selected from hydrogen and a methoxy group, and wherein each R3 is an alkyl group having 0 to 19 carbon atoms;
- b) an effective amount of one or more additives selected from the group consisting of pigment, fragrance, emulsifier, wetting agent, thickener, emollient, rheology modifier, viscosity modifier, gelling agent, antiperspirant agent, deodorant active, fatty acid salt, film former, anti-oxidant, humectant, opacifier, monohydric alcohol, polyhydric alcohol, fatty alcohol, preservative, pH modifier, a moisturizer, skin conditioner, stabilizing agent, proteins, skin lightening agents, topical exfoliants, antioxidants, retinoids, refractive index enhancer, photo-stability enhancer, SPF improver, UV blocker, and water;
- and
- c) optionally, an active ingredient selected from the group consisting of antibiotic, antiseptic, antifungal, corticosteroid, and anti-acne agent.
A pharmaceutical composition comprising:
- (a) a base oil comprising one or more of the following:
- (i) a branched aromatic compound having one of the following structures:
- and optionally an aliphatic enal compound having the following structure:
- or
- (ii) a branched cycloaliphatic compound having one of the following structures:
- and isomers thereof, and
- and optionally a branched aliphatic compound having the following structure:
- and isomers thereof,
- wherein R is an alkyl group having 1 to 20 carbon atoms, wherein the alkyl group is a linear, a branched, or a cycloalkyl group, wherein R1 and R2 are independently selected from hydrogen and a methoxy group, and wherein each R3 is an alkyl group having 0 to 19 carbon atoms;
- (b) an effective amount of one or more pharmaceutically active ingredients;
- and
- (c) optionally, one or more pharmaceutically acceptable excipients.
