Carrageenan Laundry Gel Matrix for Fast Dissolution Delivery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing laundry compositions fail to deliver a variety of benefit agents effectively to diverse fabrics during the laundry process, as they are not sufficiently soluble and do not cater to the varying needs of different fabric types.
Innovation Solution
A laundry composition comprising a hydrocolloid gel matrix with sodium chloride for curing, which enhances dissolution during the laundry process, allowing for the delivery of benefit agents such as perfumes, fabric softeners, and other active ingredients.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a hydrocolloid gel matrix is used to deliver benefit agents, then the delivery effectiveness to diverse fabrics is improved, but the dissolution speed during the laundry process is reduced
Solution Approach 1:
The patent changes the chemical composition parameters of the gel matrix by incorporating specific salts (sodium chloride, calcium chloride, magnesium chloride) at optimized concentrations. This modifies the gel's physical properties to achieve a balance between maintaining structural integrity for effective benefit agent delivery and enabling sufficient dissolution speed during the laundry process.
Solution Approach 2:
The patent creates a composite gel matrix system combining hydrocolloid polymers with multiple salt components. This composite structure allows the gel to exhibit both the stability needed for effective benefit agent delivery and the solubility required for timely dissolution, resolving the contradiction between these two opposing requirements.
2Speed
If the gel matrix is made more soluble to dissolve quickly, then the dissolution speed is improved, but the stability of the benefit agent delivery system is reduced
Solution Approach 1:
The patent optimizes the concentration parameters of salts within the gel matrix to achieve a critical balance point. At these specific concentrations, the gel maintains enough structural stability to preserve benefit agents during storage and handling, while simultaneously possessing sufficient solubility to dissolve at appropriate speeds during the laundry cycle.
Solution Approach 2:
The salt components act as intermediary substances that mediate between the hydrocolloid polymer chains. They modify the intermolecular forces within the gel matrix, creating a structure that is stable enough to maintain delivery system integrity but labile enough to dissolve when exposed to laundry conditions, thus resolving the stability-speed contradiction.
