Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing solid cosmetic compositions for skin and lips, such as sticks and powders, suffer from issues of homogeneity, comfort, hydration, hygiene, and sensoriality, with sticks causing repeated contact and wastage, and powders being difficult to disperse correctly, and both lacking a fatty phase and lipophilic active ingredients.
Innovation Solution
A solid cosmetic composition with a porosity greater than 20% by volume, featuring cavities that allow for a fatty phase and lipophilic active agents, providing good grip, comfortable application, and customizable packaging.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If solid cosmetic compositions are made anhydrous to improve stability and shelf life, then storage reliability is improved, but deposition homogeneity and sensoriality deteriorate due to greasy and sticky deposits
Solution Approach 1:
The patent introduces a porous solid support with controlled porosity (20-80% volume) that can absorb and release aqueous phases, enabling the composition to transition from solid to liquid state during application. This porous structure allows homogeneous distribution of active ingredients while maintaining solid form for stable storage, resolving the contradiction between storage stability and deposition homogeneity.
Solution Approach 2:
The patent changes the physical state parameters of the cosmetic composition by incorporating a porous support that can absorb water to transform the solid composition into a liquid emulsion during application. This parameter change allows the product to maintain solid form for storage stability while becoming liquid for homogeneous deposition, simultaneously improving both reliability and manufacturing precision.
2Ease of operation
If stick format is used to provide solid composition, then ease of application is improved, but hygiene deteriorates due to repeated contact between solid composition and treated keratin material
Solution Approach 1:
The patent employs single-dose packaging where the porous solid composition is sealed in individual packets. Each packet is used once and then discarded, eliminating repeated contact between the composition and the treated material. This disposable approach maintains ease of application while completely preventing hygiene contamination.
3Device complexity
If powder format is used to provide solid composition, then packaging simplicity is improved, but ease of operation deteriorates due to difficulty in adding the right amount of water and achieving proper dispersion
Solution Approach 1:
The patent pre-prepares the porous solid support with the exact amount of aqueous phase needed for optimal emulsion formation during application. The porous structure is designed to absorb and release water in controlled amounts, eliminating the need for users to manually add water and achieve proper dispersion. This preliminary preparation maintains packaging simplicity while dramatically improving ease of operation.
4Reliability
If traditional solid compositions are used without fatty phase, then stability is improved, but sensoriality and effectiveness deteriorate due to absence of lipophilic active ingredients
Solution Approach 1:
The patent creates a composite material system consisting of a porous solid support combined with a fatty phase containing lipophilic active ingredients. The porous structure provides stability and solid form, while the fatty phase delivers sensoriality and effectiveness. This composite approach combines the advantages of both stable anhydrous formulations and effective fatty phase-containing products.
Solution Approach 2:
The porous solid support acts as a carrier that can incorporate and release fatty phase components during application. The porous structure maintains composition stability while enabling the inclusion of lipophilic active ingredients that improve sensoriality and effectiveness, resolving the contradiction between stability and quality.
