Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The cosmetic and pharmaceutical industries face challenges in finding alternative hydrocarbon mixtures that are ecologically and toxicologically harmless, easily usable without complex purification, and provide improved sensory properties and skin compatibility, while also serving as stable formulations for antiperspirant/deodorant products and UV light protection.
Innovation Solution
A hydrocarbon mixture comprising 50-90% saturated linear C-11 hydrocarbons and 10-50% saturated linear C-13 hydrocarbons, which can be directly used in cosmetic and pharmaceutical preparations, offering improved stability, skin compatibility, and sensory properties, and is suitable for use with antiperspirant/deodorant active ingredients and UV light protection filters.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If traditional hydrocarbon mixtures from petrochemical processes are used, then formulation technology and sensory properties are achieved, but ecological and toxicological harm increases
Solution Approach 1:
The patent changes the chemical composition parameters by specifying precise proportions of linear C11 (50-90%) and C13 (10-50%) hydrocarbons, replacing traditional petrochemical mixtures with a defined composition that reduces harmful effects while maintaining formulation properties
Solution Approach 2:
The patent employs a simple, easily producible hydrocarbon mixture with straightforward purification that can be readily implemented in cosmetic formulations, replacing complex purification processes with a more economical and eco-friendly approach
2Object-affected harmful factors
If existing hydrocarbon mixtures are used in cosmetic preparations, then sensory properties are achieved, but skin compatibility is insufficient
Solution Approach 1:
The patent optimizes the molecular weight distribution and composition parameters of the hydrocarbon mixture, specifying C11-C13 linear hydrocarbons in defined proportions to achieve both improved skin compatibility and reliable formulation stability simultaneously
3Illumination intensity
If volatile hydrocarbons are used for decorative cosmetics, then light sensory impression is achieved, but stability during storage deteriorates
Solution Approach 1:
The patent selects specific carbon chain lengths (C11 and C13) and their proportions to optimize the balance between volatility for sensory light impression and stability for storage, achieving both desirable properties simultaneously
Solution Approach 2:
The patent creates a composite hydrocarbon mixture combining C11 and C13 linear hydrocarbons in specific ratios, where the combination provides both the desired sensory properties and storage stability that neither component alone could achieve
4Ease of manufacture
If mineral oil distillation products are used, then formulation base is provided, but purification complexity increases
Solution Approach 1:
The patent uses a hydrocarbon mixture that requires minimal purification and processing, eliminating complex purification steps and reducing overall processing complexity while maintaining formulation suitability
Solution Approach 2:
The patent extracts and isolates specific linear hydrocarbon components (C11 and C13) from more complex mixtures, removing unnecessary components and simplifying the purification process while retaining the essential formulation properties
