Detergent Opacifying Agents for Stable Cloudy Appearance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge lies in creating a detergent portion unit that is visually appealing, ecologically acceptable, and efficiently produced, particularly in achieving a stable cloudy-white appearance for white liquid detergents without using opacifying agents that are environmentally questionable.
Innovation Solution
A flowable detergent preparation containing 0.1-10% opacifying agents, 0.00001-1% colorants from red, blue, or violet groups, with a preferred use of inorganic divalent cation salts like magnesium and calcium salts, along with surfactants, fatty acids, and solvents, to maintain a stable cloudy-white appearance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If traditional organic opacifying agents are used to achieve a cloudy-white appearance, then the aesthetic quality is improved, but the ecological acceptability deteriorates
Solution Approach 1:
The patent changes the chemical composition parameters by replacing organic opacifying agents with inorganic divalent cation salts (calcium, magnesium). This parameter substitution maintains the desired cloudy-white appearance while eliminating the ecological harmfulness of organic additives, directly resolving the contradiction between aesthetic quality and ecological acceptability.
Solution Approach 2:
The patent employs inexpensive inorganic salts that are naturally occurring and biodegradable. These divalent cation salts serve as temporary, non-persistent additives that provide the required optical properties without long-term environmental harm, replacing the more problematic organic opacifying agents.
2Object-affected harmful factors
If inorganic divalent cation salts are used as opacifying agents, then the ecological acceptability is improved, but the stability of appearance over time may deteriorate
Solution Approach 1:
The patent creates a composite detergent system combining inorganic divalent cation salts with specific anionic and nonionic surfactants. This composite formulation ensures that the inorganic salts remain stable and effective over time, maintaining both ecological acceptability and appearance stability through the synergistic interaction of multiple components.
Solution Approach 2:
The patent optimizes the concentration parameters of divalent cation salts within specific ranges (0.1-10% by weight) and combines them with controlled amounts of surfactants. This parameter optimization ensures that the inorganic salts maintain stable appearance properties over time while remaining ecologically acceptable, resolving the stability concern.
3Productivity
If highly concentrated detergent is used to reduce packaging volume, then the productivity is improved, but the ease of operation deteriorates
Solution Approach 1:
The patent adjusts the rheological parameters of the detergent formulation by selecting specific surfactant types and their concentrations. This parameter adjustment ensures that even highly concentrated detergent maintains optimal flow properties and handling characteristics, resolving the contradiction between concentration and ease of operation.
Solution Approach 2:
The patent uses surfactants as intermediary substances that mediate between the high concentration requirement and the ease of operation requirement. The surfactants modify the physical properties of the concentrated detergent, enabling it to flow and handle easily despite the high concentration of active ingredients.
4Manufacturing precision
If energy input is increased during mixing to achieve homogeneous distribution, then the manufacturing precision is improved, but the loss of energy increases
Solution Approach 1:
The patent formulates a detergent system where the surfactants continuously stabilize the homogeneous distribution of ingredients during mixing. This continuous stabilization reduces the total energy input required, as the formulation maintains uniformity without requiring excessive mechanical energy, thus resolving the contradiction between manufacturing precision and energy loss.
