Cosmetic Cooling Composition with Extended Duration Complex
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cosmetic cooling compositions have limited long-lasting cooling effects, typically lasting up to 90 minutes, whereas the goal is to achieve a cooling effect that lasts for at least 120 minutes and preferably up to 8 hours.
Innovation Solution
A cosmetic composition comprising a cooling complex of 0.05-0.15% Menthyl Lactate, 0.1-0.2% Menthyl PCA, and 0.05-0.2% Ethyl Menthane Carboxamide, combined with silicone oils, alcohols, and other cosmetic auxiliaries, which forms a clear gel or spray, providing a sustained cooling effect.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If conventional cooling compositions (menthol, isopulegol, menthoxypropanediol) are used, then a cooling effect is achieved, but the duration is limited to 30-90 minutes
Solution Approach 1:
The patent combines three different cooling agents (menthyl lactate, menthyl PCA, and ethyl menthane carboxamide) into a single cooling complex. Each component contributes to the cooling effect through different mechanisms and time profiles, creating a synergistic formulation that extends total cooling duration from 30-90 minutes to 120-480 minutes while maintaining consistent relief throughout the extended period.
Solution Approach 2:
The invention uses a composite cooling complex where multiple chemically distinct compounds work together. The complex includes esters of menthol with different carboxylic acids (lactate, PCA) and an amide derivative (ethyl menthane carboxamide), creating a multi-component system that provides prolonged and reliable cooling through complementary mechanisms.
2Duration of action of moving object
If the concentration of cooling agents is increased to extend duration, then cooling effect lasts longer, but the formulation may become less clear or have impaired cosmetic properties
Solution Approach 1:
The patent optimizes the concentration parameters of each cooling agent within specific ranges (menthyl lactate: 0.05-0.15%, menthyl PCA: 0.1-0.2%, ethyl menthane carboxamide: 0.05-0.2%) to achieve extended cooling duration while maintaining gel clarity. The total concentration of cooling agents is kept at 0.2-0.55%, which provides sufficient cooling effect without compromising the aesthetic properties of the clear gel formulation.
