Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fragrance premix compositions face challenges in achieving efficient perfume deposition on target surfaces due to limited loading capacity and interactions between aminosilicones and perfume raw materials, leading to suboptimal performance and potential discoloration issues.
Innovation Solution
A fragrance premix composition comprising a silicone polymer, an aminofunctional material, and a fragrance material with specific characteristics, including a 9.9:0.1:0.1 weight ratio, ensuring miscibility and improved perfume deposition by decoupling amine groups from the silicone polymer, thereby enhancing loading efficiency and color stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the amine content of the aminosilicone is increased to improve loading capacity and interactions with perfume raw materials, then the solubility of the aminosilicone increases, but this reduces its tendency to be easily emulsified in water and deposit onto fabric
Solution Approach 1:
The invention separates the amine-containing compound from the silicone polymer into two distinct components: a silicone polymer and a separate amine-containing compound. This segmentation allows each component to maintain its optimal properties independently - the silicone remains hydrophobic and emulsifiable, while the amine compound provides sufficient amine groups for perfume loading without compromising the silicone's water interaction properties.
Solution Approach 2:
The amine-containing compound acts as an intermediary substance that mediates between the hydrophobic silicone polymer and the perfume raw materials. It provides the necessary amine groups for interactions and loading capacity while not being part of the silicone structure itself, thus allowing the silicone to maintain its emulsification and deposition capabilities.
2Productivity
If other amine-containing (non-silicone) compounds are used to improve perfume deposition, then deposition efficiency increases, but undesirable discoloration of perfume premixes and final products occurs
Solution Approach 1:
The invention changes the chemical parameters of the amine-containing compound by specifying particular structural characteristics (such as using specific types of amine groups and molecular structures) that provide sufficient reactivity for perfume deposition while avoiding the discoloration issues associated with other amine compounds. The compound is selected to have appropriate molecular weight and functional group characteristics.
3Quantity of substance
If the aminosilicone is made too hydrophilic to improve solubility, then certain hydrophobic perfume raw materials will not partition into the silicone droplets, but this results in suboptimal perfume deposition upon usage
Solution Approach 1:
The system is segmented into distinct hydrophobic (silicone polymer) and hydrophilic (amine-containing compound) components that work together. The hydrophobic silicone maintains its ability to partition hydrophobic perfume raw materials into droplets, while the separate amine compound provides solubility and deposition enhancement without compromising the hydrophobic nature of the silicone phase.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution results in increased perfume loading and efficient deposition on surfaces, maintaining color stability and improving perfume performance in consumer products.
Implementation Method 1
deposition efficiency may further increase due to interactions between the amine groups of the aminosilicone and the PRMs
Implementation Method 2
if the aminosilicone is too hydrophilic, it is believed that certain PRMs, many of which are relatively hydrophobic, will not partition into the silicone droplets
