Porous Dissolvable Substrate Perfume Complex
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional personal care products, especially perfumed ones, face limitations in delivering perfumes efficiently due to water content, which traps perfume molecules in aqueous assemblies, reducing their delivery to the nostrils and skin/hair, and restricts the use of water-activated perfumes, offering only a single scent experience.
Innovation Solution
A personal care article comprising a porous dissolvable solid substrate with a surface resident inorganic particulate perfume complex, allowing for efficient water-activated perfume release, providing both primary and secondary perfume experiences through a unique delivery mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If perfume is solubilized or emulsified in aqueous personal care products, then the product can be formulated with water, but a significant portion of perfume molecules are trapped in aqueous assemblies, limiting efficient delivery to nostrils and skin
Solution Approach 1:
The patent extracts perfume molecules from aqueous assemblies by using supercritical carbon dioxide to directly deposit perfume onto the solid substrate surface. This eliminates the water-based solubilization/emulsification step that traps perfume molecules, allowing direct application of free perfume molecules to the substrate without being confined in micelles or liquid crystals.
Solution Approach 2:
The patent changes the physical state and delivery mechanism of perfume by depositing it as a surface coating on a solid substrate rather than dissolving it in water. This parameter change from aqueous solution to solid surface deposition enables controlled release of perfume molecules without trapping them in water-based assemblies, improving both delivery efficiency and perfume bloom.
2Adaptability or versatility
If traditional liquid personal care products are used, then perfumes can be included, but only a single scent experience is delivered and water-activated perfumes cannot be used
Solution Approach 1:
The patent segments the perfume delivery into two distinct components: a primary perfume incorporated into the solid substrate and a secondary water-activated perfume applied as a surface coating. This segmentation allows both perfumes to be delivered in sequence - the primary perfume provides the packaged scent and the secondary perfume activates upon water contact, creating a multi-stage scent experience without complicating the overall product formulation.
3Quantity of substance
If more perfume is included in personal care products, then higher perfume levels can be achieved, but water content traps perfume molecules in assemblies, reducing effective delivery
Solution Approach 1:
The patent uses a solid substrate as an intermediary carrier that holds the perfume on its surface rather than in an aqueous solution. This intermediary solid matrix allows high perfume concentration to be maintained without the trapping effect of water, as the perfume molecules remain accessible on the substrate surface and can be reliably delivered to the skin and hair during product application.
