Layered Solid Personal Care Product for Low-Water Ingredient Compatibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional personal care products face issues such as messiness, inefficiency in customization, high water content leading to increased carbon footprint, and incompatibility of beneficial cosmetic ingredients due to the use of anionic surfactants.
Innovation Solution
A method of forming personal care products with multiple layers, each with independent compositions, using a binder to adhere them, allowing for the inclusion of incompatible ingredients and reducing water content.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If liquid based cleansing products are used, then effective cleansing is achieved, but the products become messy, difficult to dose, and prone to leakage
Solution Approach 1:
The patent changes the physical state parameter of the cleansing product from liquid to solid form. The solid personal care product maintains cleansing effectiveness through surfactant inclusion while eliminating the messiness, dosage control issues, and leakage problems associated with liquid products.
Solution Approach 2:
The patent creates a composite solid structure combining surfactants, fillers, and binding agents. This composite material achieves the desired solid form with effective cleansing properties, merging the benefits of solid stability with liquid cleansing capability.
2Reliability
If liquid based cleansing products are used, then cleansing function is provided, but water content increases weight and carbon footprint
Solution Approach 1:
The patent reduces the water content parameter from high (liquid based) to low (solid based). This parameter change significantly decreases product weight and carbon footprint while maintaining cleansing function through the surfactant system in solid form.
3Quantity of substance
If high water content is used in cleansing products, then ingredient stability is compromised, but ingredient incorporation is limited
Solution Approach 1:
The patent changes the water content parameter from high to low, creating a stable environment for water-sensitive ingredients like vitamin C. This parameter change prevents hydrolysis and degradation, significantly improving ingredient stability.
4Reliability
If anionic surfactants are used for cleansing, then effective cleaning is achieved, but incompatible cosmetic ingredients cannot be incorporated
Solution Approach 1:
The patent segments the product into multiple layers, with each layer containing specific ingredients. This segmentation allows incompatible ingredients to be separated into different layers, enabling the incorporation of both anionic surfactants and previously incompatible cosmetic ingredients like cationic surfactants, oils, and antibacterial agents.
Solution Approach 2:
The patent creates a multi-layer composite structure where each layer is formulated with compatible ingredients. This composite approach allows the overall product to contain both anionic surfactants for cleansing and various cosmetic ingredients that would be incompatible in a single-phase system.
5Weight of moving object
If solid based cleansing products are used, then water content is reduced, but products are perceived as harsh and provide insufficient foam
Solution Approach 1:
The patent formulates the solid product as a composite containing surfactants, fillers, and binding agents in specific ratios. This composite formulation maintains low water content while ensuring adequate foam generation and gentle performance through proper ingredient selection and concentration.
Solution Approach 2:
The patent optimizes the concentration and type of surfactants in the solid formulation to achieve sufficient foam generation. By adjusting surfactant parameters (type, concentration, combination), the product overcomes the traditional limitation of solid-based low-foam performance.
