Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Taurine re-crystallization in soap bars leads to an undesirable rough surface, which is not effectively addressed by existing methods when incorporated as a solid additive.
Innovation Solution
Incorporating taurine as an aqueous solution or taurine salt into the soap bar formulation to prevent re-crystallization, using a specific method that involves combining fatty acid soap with the taurine solution or salt to form an amalgamate and then preparing the soap bar, with the taurine or taurine salt represented by a specific formula, thereby maintaining a smooth surface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If taurine is incorporated as a solid additive into soap bar precursor formulations, then the manufacturing process is simple, but re-crystallization of taurine occurs during aging producing a rough surface
Solution Approach 1:
The patent changes the physical state parameter of taurine from solid to dissolved form in water or alcohol. By dissolving taurine in a liquid carrier before incorporation into the soap base, the formulation prevents re-crystallization during aging while maintaining ease of manufacture. The liquid carrier ensures uniform distribution and suppresses crystal formation.
Solution Approach 2:
The patent introduces water or alcohol as an intermediary carrier substance. This intermediary medium dissolves taurine and prevents direct contact between taurine molecules that would lead to crystallization. The carrier acts as a barrier that maintains taurine in solution throughout the aging process.
2Device complexity
If taurine is incorporated as a solid additive, then the formulation is straightforward, but the soap bar surface becomes rough after aging
Solution Approach 1:
The patent modifies the formulation by changing taurine from solid particles to dissolved state in liquid carrier. This parameter change increases initial formulation complexity slightly but eliminates the surface roughening problem during aging, achieving long-term formulation stability.
3Reliability
If taurine is used in soap bar, then functional benefits are provided, but re-crystallization produces undesirable rough surface
Solution Approach 1:
The patent uses water or alcohol as an intermediary carrier to dissolve taurine, preventing the harmful re-crystallization effect while preserving the functional benefits of taurine in the soap bar. The intermediary maintains taurine in a stable dissolved state throughout the product lifecycle.
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 method effectively inhibits taurine re-crystallization, resulting in a smooth soap bar surface even after aging, enhancing the product's desirability for skin application.
Implementation Method 1
when taurine is incorporated into soap bar precursor formulations (amalgamates) as a solid additive, after manufacturing of the soap bar and on aging of the soap bar, re-crystallization of taurine occurs. Re-crystallization of taurine produces a rough surface which is undesirable for the consumer.
