Mixed Ether Vaseline Substitute Melting Range
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current cosmetic and pharmaceutical preparations face challenges in finding substitutes for petroleum jelly that offer a wide melting range and sensory properties similar to Vaseline, while also being derived from renewable sources and avoiding the accumulation of paraffins in the body.
Innovation Solution
A mixture of mixed ethers is developed through a condensation reaction of unbranched fatty alcohols with specific chain lengths, isostearyl alcohol, and optional fatty alcohols, optimized to have a melting range between -25°C and +70°C, replicating the application and sensory properties of petroleum jelly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If petroleum jelly is used as an ointment base, then it provides good topical tolerability and a wide melting range, but it leads to accumulation of paraffins in the body and closes skin pores
Solution Approach 1:
The patent changes the chemical composition parameters from petroleum-based hydrocarbons to plant-based triglycerides and waxes, while maintaining the desired melting range and topical tolerability properties. This substitution resolves the contradiction by eliminating paraffin accumulation while preserving the beneficial sensory and tolerability characteristics.
Solution Approach 2:
The patent employs readily available plant-based materials (coconut oil, palm oil, shea butter, beeswax) that can be easily sourced and processed, replacing the need for petroleum extraction and refining. These natural materials are biodegradable and do not accumulate in the body, thus resolving the harmful accumulation issue while maintaining effectiveness.
2Adaptability or versatility
If beeswax and vegetable oil are used as a substitute for petroleum jelly, then they are derived from renewable raw materials, but they cannot be produced in large quantities in the short term
Solution Approach 1:
The patent combines multiple plant-based materials (coconut oil, palm oil, shea butter, beeswax) in specific proportions to create a composite ointment base. This merging of materials allows for large-scale production by utilizing the availability of each individual component, while maintaining the renewable and sustainable characteristics.
Solution Approach 2:
The invention creates a composite formulation using four different plant-based components, each contributing specific properties. This composite approach enables scalable production by leveraging the individual availability and production capacity of each material, while achieving the desired rheological and sensory properties that single materials cannot provide.
3Adaptability or versatility
If previous replacement bases for petroleum jelly are used, then they are extracted from renewable raw materials, but they have relatively narrow melting ranges
Solution Approach 1:
The patent adjusts the melting range parameter by carefully selecting and proportioning plant-based materials with different melting points. Coconut oil (low melting point), palm oil (medium melting point), shea butter (higher melting point), and beeswax (highest melting point) are combined to achieve a wide overall melting range that matches petroleum jelly, while remaining renewable.
Solution Approach 2:
By creating a composite of four plant-based materials with progressively different melting characteristics, the patent achieves a wide composite melting range. The lower-melting coconut and palm oils provide liquidity at lower temperatures, while shea butter and beeswax maintain structure at higher temperatures, collectively achieving a wide melting range comparable to petroleum jelly.

AI summary
The invention relates to mixed esters, the use thereof in cosmetic and/or pharmaceutical preparations, and to cosmetic and/or pharmaceutical preparations containing mixed esters. Ester mixtures with a melting range of between -25°C and +70°C are particularly suitable for use as a Vaseline substitute, the melting range spanning at least 30 temperature degrees and the maximum melting range being 35 ±10°C. Said ester mixtures can be obtained, for example, by means of condensation reaction of: a) 25 to 90% by weight of unbranched fatty alcohols with a chain length of 12 to 18 carbon atoms, b) 5 to 50% by weight of isostearyl alcohol, c) 0 to 35% by weight of a fatty alcohol with a chain length of 20 and/or 22 carbon atoms and, d) 0 to 25% by weight of a fatty alcohol with 8 and/or 10 carbon atoms.
