Perfume Composition with Hydroxy Esters for Malodor Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current perfumes are often ineffective at low concentrations and unstable in various detergent and personal care products, particularly failing to effectively counteract malodors such as smoke and kitchen smells, while also being difficult to incorporate into consumer products without affecting storage stability.
Innovation Solution
A perfume composition comprising 0.1 to 40% Petit grain oil and 99.9 to 60% hydroxy carboxylic acid esters, optionally with terpenes and essential oils, which exhibits synergistic behavior to combat multiple malodors simultaneously, including cigarette smoke, kitchen, and bathroom smells, at low concentrations and maintains stability in various consumer products.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If perfume intensity is increased to achieve effective odour masking, then malodour counteraction improves, but dosage levels exceed preferred limits and customer acceptance decreases
Solution Approach 1:
The invention changes the chemical composition parameters of the perfume by incorporating specific esters (citrate, malate, tartrate) with hydroxy groups that have high malodour counteraction activity. This allows achieving effective malodour control at lower concentration levels (0.01-5% in the final product) compared to conventional perfumes, thus resolving the contradiction between effectiveness and dosage level
Solution Approach 2:
The invention creates a composite perfume formulation combining multiple ester components (citrate, malate, tartrate esters) with specific hydroxy groups. This composite approach synergistically enhances malodour counteraction activity, allowing effective performance at reduced dosage levels that are both formulation-friendly and customer-acceptable
2Ease of manufacture
If perfume composition is simplified for ease of incorporation, then manufacturing ease improves, but stability in various detergent and personal care products deteriorates
Solution Approach 1:
The invention modifies the chemical parameters of the perfume components by selecting esters with specific hydroxy groups that provide inherent stability. These modified ester structures resist degradation in various detergent and personal care product formulations, achieving both ease of incorporation and storage stability simultaneously
3Quantity of substance
If perfume concentration is reduced to meet customer preferences, then customer acceptance improves, but effectiveness against multiple malodours deteriorates
Solution Approach 1:
The invention changes the quality parameters of the perfume molecules by incorporating esters with hydroxy groups that possess high intrinsic malodour counteraction activity. This quality enhancement allows the perfume to be effective at lower concentrations, resolving the contradiction between concentration and effectiveness
Solution Approach 2:
The invention formulates a composite perfume system using multiple ester types (citrate, malate, tartrate) that work synergistically to provide broad-spectrum malodour counteraction. This composite structure maintains effectiveness against various malodours (body odour, sweat, smoke, kitchen, bathroom) at reduced concentration levels that meet customer preferences
