Effervescent Powder Cosmetic Composition Hydration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cosmetic compositions in solid and liquid forms face issues such as deformation, waste generation, difficulty in use, especially for children, and leakage, which affect their effectiveness and hygiene in skin and hair care.
Innovation Solution
A powder cosmetic composition comprising 60-95% of an effervescent system with carbonate or bicarbonate salts, 1-35% of solid surfactants, and 0.05-5% of crosslinked organosiloxane polymer particles supporting silica, which forms a self-supporting compact form and hydrates into a creamy foam for easy application and rinsing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If solid soap is used for skin cleansing, then it provides effective cleaning, but it deforms and breaks up after repeated use, becoming difficult to handle
Solution Approach 1:
The patent changes the physical state parameter of the cosmetic composition from solid to powder form. The powder composition maintains cleaning effectiveness while eliminating the deformation and breaking issues of solid soap. The powder can be easily handled, stored, and transported without the geometrical form degradation that plagues solid soaps after repeated use.
2Ease of operation
If liquid soap is used to overcome solid soap disadvantages, then it improves ease of use, but it becomes difficult to dose and tends to leak from containers
Solution Approach 1:
The patent uses powder form instead of liquid form, changing the physical state parameter. The powder composition can be easily dosed by controlling the amount dispensed, and it does not leak from containers. The powder maintains ease of use through simple dispensing mechanisms while eliminating the leakage and dosing difficulties associated with liquid soaps.
3Reliability
If solid soap is used, then it provides cleansing function, but it generates high quantities of unused residues that must be discarded
Solution Approach 1:
The patent adopts a disposable powder cartridge system where each cartridge contains a predetermined amount of powder composition sufficient for a specific number of applications. After use, the entire cartridge is discarded. This eliminates waste from partially used solid soaps and broken pieces, as the powder is contained in a sealed cartridge that prevents contamination and ensures complete utilization of the product.
4Loss of substance
If powder composition is used, then it eliminates waste and improves hygiene, but it requires transformation into foam form for application
Solution Approach 1:
The patent employs a hydration mechanism where water is introduced to the powder composition in the cartridge, transforming it into a foam or paste form suitable for application. This pneumatic/hydraulic transformation simplifies the application process while maintaining the waste-reduction benefits of the powder format. The water activation creates an easily applicable foam that can be spread and rinsed off conveniently.
