Solid Cosmetic Composition for Bath Dispersion and Fragrance Release
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing therapeutic bathing products face issues with environmental waste from packaging, delayed release of active ingredients, and the need for separate fragranced products, while also experiencing separation of components during fragrance delivery.
Innovation Solution
A solid cosmetic composition comprising vegetable butter, specific emulsifiers with HLB values of 2 to 9 and 10 to 20, inert powders, and fragrances, which allows for dispersion in bathing water and fragrance release upon heating, preventing separation and facilitating easy removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If encapsulated compositions with gelatinous or membrane-bound shells are used to deliver therapeutic ingredients, then the active ingredients are protected and can be delivered into water, but the shell does not readily dissipate in water delaying release, and the shell is prone to rupturing resulting in wasted product
Solution Approach 1:
The invention extracts and eliminates the problematic shell/encapsulation layer from the system. Instead of using gelatinous or membrane-bound shells that delay dissolution and are prone to rupturing, the patent uses a solid composition that directly dissolves in water without requiring an outer protective layer, thereby eliminating the release delay and rupture issues while still protecting active ingredients through the solid matrix structure
Solution Approach 2:
The invention changes the physical state parameter of the cosmetic composition from encapsulated/liquid form to solid form. This parameter change enables the composition to maintain structural integrity without a shell while still controlling the release of active ingredients through the solid matrix, resolving the contradiction between stability and release speed
2Adaptability or versatility
If separate fragranced products like reed diffusers are purchased to enjoy fragrance without bathing, then fragrance can be delivered independently, but this results in further cost to the user and potential for further unnecessary packaging and transport waste
Solution Approach 1:
The invention makes the solid cosmetic composition multi-functional by enabling it to serve both as a therapeutic bathing product and as a fragrance delivery system. The composition can be used directly in bathwater for therapeutic effects, or placed in fragrance diffusers or burners to deliver fragrance without water, thereby eliminating the need for separate fragranced products and reducing packaging waste
Solution Approach 2:
The invention merges the functions of therapeutic bathing products and fragranced products into a single unified composition. By incorporating both therapeutic active ingredients and fragrance components in the same solid matrix, the product combines multiple functions that previously required separate products, reducing overall packaging and transport requirements
3Productivity
If solid cosmetic composition is heated for fragrance release, then fragrance can be delivered effectively, but components may separate during heating
Solution Approach 1:
The invention uses a composite material structure consisting of vegetable butter as the continuous phase and inert powders dispersed within it. This composite structure provides thermal stability during heating, preventing component separation while allowing effective fragrance delivery. The inert powders act as a stable matrix that maintains homogeneity even when the vegetable butter melts and becomes more fluid
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 composition provides a dual-use product for bathing and fragrance delivery without packaging waste, ensuring effective ingredient dispersion and easy handling.
Implementation Method 1
the solid product holds its form and does not readily melt prior to use... the melting point of a soft vegetable butter would allow the composition to readily melt and dissipate
Implementation Method 2
a first emulsifier having a HLB value of from 2 to 9; (c) a second emulsifier having a HLB value of from 10 to 20
