Transparent Liquid Composition Using Specific Surfactant Ratios
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current non-alcohol fragrance products with water as the main solvent face challenges in achieving a high perfume concentration while maintaining transparency, due to difficulties in solubilizing and emulsifying perfumes, often resulting in a cloudy appearance and limited usage.
Innovation Solution
A transparent liquid composition is achieved by using PEG-40 Hydrogenated Castor Oil and PPG-26-Buteth-26 as main solubilizers, along with a surfactant having an IOB value of 0.70-1.20 as an auxiliary solubilizer, at specific blending ratios, to stabilize a high concentration of perfumes in water without substantial ethyl alcohol content.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If water is used as the main solvent to avoid oiliness and meet safety concerns, then consumer safety and comfort are improved, but the ability to stably dissolve high concentration of perfume deteriorates
Solution Approach 1:
The patent introduces a specific surfactant system (main solubilizer and auxiliary solubilizer) as an intermediary between water and perfume. This surfactant system enables high concentration of perfume to be stably dissolved in water without ethyl alcohol, resolving the contradiction between safety (no ethyl alcohol) and perfume concentration capability.
Solution Approach 2:
The patent changes the chemical parameters of the solubilizer system by specifying precise IOB values (0.70-1.20 for auxiliary solubilizer, 2000-5000 for main solubilizer) and blending ratios (0.03-0.60 for auxiliary to main solubilizer). These parameter optimizations enable stable high-concentration perfume dissolution in water-based formulations.
2Quantity of substance
If surfactants are increased to improve perfume solubilization in water, then perfume concentration is improved, but stickiness and cloudiness worsen
Solution Approach 1:
The patent applies local quality by differentiating the functions of two surfactant components: the main solubilizer (PEG-40 Hydrogenated Castor Oil with specific IOB value) handles bulk solubilization, while the auxiliary solubilizer (with IOB value 0.70-1.20) provides targeted assistance. This division of labor achieves high perfume concentration without excessive stickiness or cloudiness.
Solution Approach 2:
The patent uses a composite surfactant system combining PEG-40 Hydrogenated Castor Oil with specific auxiliary surfactants (IOB value 0.70-1.20) in controlled ratios. This composite approach provides synergistic effects that enable high perfume solubilization while maintaining transparency and reducing stickiness compared to single surfactant systems.
3Quantity of substance
If perfume concentration is increased to meet consumer demand for fragrance intensity, then fragrance performance is improved, but appearance transparency deteriorates
Solution Approach 1:
The patent optimizes the IOB values and blending ratios of the surfactant system to achieve a critical balance point where high perfume concentration (3-20% by mass) can be maintained while preserving transparency. The specific parameter ranges (auxiliary solubilizer IOB: 0.70-1.20, main solubilizer IOB: 2000-5000, blending ratio: 0.03-0.60) ensure both fragrance intensity and appearance quality.
