Isosorbide Caprylates/Caprates in Deodorants
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing antiperspirants and deodorants often rely on complex, synthetic ingredients and aluminum-based compounds, which are toxicologically concerning and require high concentrations for effective long-lasting body odor reduction, with a need for alternatives that are based on renewable materials and provide prolonged efficacy exceeding 24 hours.
Innovation Solution
The use of isosorbide caprylates/caprates, specifically in mixtures with sorbitan caprylates/caprates, in compositions that are at least 50% by weight, which are derived from renewable sources and are toxicologically harmless, improving the duration of body odor reduction in antiperspirants and deodorants.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If aluminum-containing substances are used in antiperspirants and deodorants, then the effectiveness in reducing body odor is improved, but toxicological safety deteriorates
Solution Approach 1:
The patent changes the chemical composition parameters by replacing aluminum-containing compounds with isosorbide caprylate/caprate esters. This substitution maintains the functional effectiveness of body odor reduction while eliminating the toxicological concerns associated with aluminum substances, thus resolving the contradiction between reliability and harmful factors.
Solution Approach 2:
The patent employs renewable raw materials (isosorbide derived from sugars) combined with fatty acid esters to create a biodegradable, non-toxic alternative to persistent aluminum compounds. This approach uses naturally derived, environmentally friendly substances that are safe for skin contact while maintaining deodorant functionality.
2Reliability
If high concentrations of active ingredients are used to achieve sufficient efficacy, then the effectiveness in reducing body odor is improved, but the complexity of the composition and potential toxicity increase
Solution Approach 1:
The patent modifies the concentration parameters by achieving effective body odor reduction with lower concentrations of active ingredients. The isosorbide caprylate/caprate esters demonstrate high efficacy at reduced levels, simplifying the overall composition and reducing the need for complex formulations with multiple high-concentration components.
3Reliability
If conventional synthetic ingredients are used, then the availability and consistency of the product are improved, but the renewability and environmental sustainability deteriorate
Solution Approach 1:
The patent creates a composite material system combining isosorbide (a renewable polyol derived from sugar) with caprylate/caprate fatty acid esters. This composite approach maintains product consistency and availability while incorporating renewable, sustainably sourced ingredients, thus resolving the contradiction between reliability and environmental sustainability.
Solution Approach 2:
The patent changes the sourcing parameters of the raw materials from synthetic petroleum-based chemicals to renewable biomass-derived ingredients. Isosorbide is produced from fermented sugars, and the fatty acid esters can be derived from plant oils, ensuring both product consistency and environmental sustainability.
