Jasmol and BHT Composition for Laundry Malodor Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current laundry care products face challenges in preventing musty, mouldy odors on clothes and in washing machines, particularly at lower washing temperatures and without the use of strong antimicrobial agents like Triclosan, cationic surfactants, or silver salts, which can lead to multi-resistant microorganism formation and stability issues at high temperatures.
Innovation Solution
A composition comprising 2-benzylheptanol (Jasmol) and 3,5-di-tert-butyl-4-hydroxytoluene (BHT) is used, along with optional solvents and natural extracts, to reduce malodor at lower concentrations, effectively targeting both clothes and washing machines without the need for high antimicrobial agents.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If strong antimicrobial active compounds like Triclosan, cationic surfactants or silver salts are used at high concentrations, then malodor prevention is improved, but multi-resistant microorganism formation is triggered and biodegradability problems occur
Solution Approach 1:
The patent changes the concentration parameter of antimicrobial agents from high to low (0.01-5 wt%), and introduces a synergistic combination of Jasmol and BHT that achieves effective malodor prevention at these reduced concentrations while minimizing harmful effects of antimicrobial resistance
Solution Approach 2:
The patent creates a composite composition combining Jasmol (2-benzylheptanol) and BHT (3,5-di-tert-butyl-4-hydroxytoluene) in specific ratios, where the synergistic interaction between these two compounds provides enhanced malodor prevention effectiveness at low concentrations without triggering multi-resistant microorganism formation
2Reliability
If washing temperatures are raised above 60°C to prevent malodor, then odor control is improved, but damage to clothes and energy consumption increase
Solution Approach 1:
The patent changes the temperature parameter from high (>60°C) to low (20-40°C), and compensates for the reduced thermal effect by introducing a synergistic chemical composition of Jasmol and BHT that remains effective at lower temperatures while preventing malodor formation
3Reliability
If high concentrations of antimicrobial agents are used to ensure effectiveness, then malodor reduction is improved, but stability at high temperatures deteriorates
Solution Approach 1:
The patent creates a composite system where BHT (a known antioxidant and stabilizer) protects Jasmol from degradation at high temperatures, while the synergistic interaction between both compounds ensures effective malodor reduction. This composite structure provides both effectiveness and thermal stability
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 significantly reduces musty, mouldy malodor intensity, demonstrating a synergistic effect with Jasmol and BHT, providing effective odor control in laundry care products at lower concentrations and lower washing temperatures, thus minimizing the risks associated with high antimicrobial agent use.
Implementation Method 1
Jasmol (2-benzylheptanol) is used as antimicrobial active substance in cosmetic products
Implementation Method 2
BHT (3,5-Di-tert-butyl-4-hydroxytoluol) is used as antioxidant in cosmetic products or products for household, perfumery, food etc.
