Solution Overview

Problem

Conventional methods for obtaining jojoba esters require extracting oil from jojoba seeds, processing it through transesterification, which is costly and limited in supply, while synthetic alternatives lack equivalent physical and sensory attributes.

Innovation Solution

Synthesizing wax ester compositions through transesterifying specific ratios of fatty acids and fatty alcohols using chemical, enzyme, or bio-based catalysts, replicating the physical and sensory attributes of jojoba esters by achieving equivalent iodine values, dropping points, and molecular weights.

Solution Approach 1:

The patent creates a synthetic copy of jojoba esters by combining specific esters (C36 and C44 chain length esters) in defined ratios to replicate the physical and chemical properties of natural jojoba esters. This synthetic approach copies the functional characteristics without requiring extraction from natural sources, thereby reducing cost and supply limitations while maintaining reliability of properties

Inventive Principle:
Principle #26Copying

Solution Approach 2:

The patent specifies precise parameter ranges for the synthetic esters, including carbon chain lengths (C36: 32-38 carbons, C44: 40-48 carbons) and their ratios (65-85% C36, 15-35% C44), to match the molecular characteristics of natural jojoba esters. By controlling these parameters, the synthetic composition achieves equivalent physical and chemical properties while avoiding the limitations of natural extraction

2Ease of manufacture

If synthetic wax esters are produced to reduce cost, then manufacturing cost decreases, but physical and sensory attributes are not equivalent to jojoba esters

Engineering Contradiction:
Improvemanufacturing costVSAvoidphysical and sensory attributes
Core Design Contradiction:
Ease of manufactureVSReliability

Solution Approach 1:

The patent focuses on achieving the specific local quality of jojoba esters by selecting esters with precise carbon chain lengths (C36 and C44) that correspond to the molecular structure of natural jojoba esters. This targeted selection of specific molecular characteristics ensures that the synthetic product replicates the local physical and sensory properties where they matter most for cosmetic applications

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The patent creates a composite synthetic wax ester composition by combining two different ester types (C36 and C44 chain length esters) in specific ratios. This composite approach allows the synthetic material to achieve the complex physical and sensory attributes of natural jojoba esters through the synergistic combination of components, rather than using a single ester type

Inventive Principle:
Principle #40Composite materials

AI summary

Implementations of wax ester compositions may include: a product of transesterifying oleyl oleate, stearyl stearate, and behenyl behenate using one of a chemical or an enzyme catalyst. The ratio of the oleyl oleate to stearyl stearate to behenyl behenate in the mixture prior to transesterification is one of 65%/23%/12%, 56%/29%/15%, or 36%/34%/30%, respectively, measured by weight. The product may demonstrate a substantially equivalent physical property to a physical property of a transesterified wax ester composition including a jojoba ester.
