Solid Textile Care Composition with Bentonite Carrier
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional fabric softeners cannot be used simultaneously with washing detergents due to interactions with anionic surfactants, requiring an additional rinse cycle, and often leave unattractive deposits in washing machines, including the bleach dispenser.
Innovation Solution
A solid textile- and/or skin-care composition comprising a water-soluble particle and a water-insoluble particle with a textile- and/or skin-care compound, allowing for use in the main washing cycle without the need for an additional rinse, using a water-insoluble carrier like bentonite and incorporating perfume and polysiloxanes for enhanced softening and scent.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If conventional fabric softeners are used, then textile softness is improved, but an additional rinse cycle is required due to interaction with anionic surfactants
Solution Approach 1:
The invention extracts the cationic textile-softening compound from the aqueous fabric softener formulation and applies it directly to the solid washing detergent or cleaning agent. This extraction allows the softening agent to be present during the main washing cycle without interfering with anionic surfactants, as it is delivered through a different vehicle (solid composition rather than aqueous fabric softener), thereby eliminating the need for an additional rinse cycle while maintaining textile softness.
2Stability of the object's composition
If conventional fabric softeners are used, then textile softness is improved, but lime deposits are formed in the washing machine
Solution Approach 1:
The invention merges the textile-softening function with the washing detergent or cleaning agent by incorporating the cationic textile-softening compound into the solid composition. This combination allows simultaneous delivery of both cleaning agents and softening agents during the main washing cycle, ensuring that the softening compound is applied at the appropriate time and in the appropriate form, thereby preventing lime deposit formation while maintaining textile softness.
3Stability of the object's composition
If conventional fabric softeners are used, then textile softness is improved, but unattractive deposits are left in the bleach dispenser
Solution Approach 1:
The invention extracts the textile-softening function from the separate aqueous fabric softener product and integrates it into the solid washing detergent or cleaning agent formulation. This extraction and integration eliminate the need for a separate fabric softener bottle in the bleach dispenser, thereby preventing unattractive deposits while maintaining the ability to soften textiles effectively.
