Glycolipid and Triethyl Citrate Composition for Acidic pH Foaming
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Rhamnolipids exhibit decreased foaming ability at pH levels commonly used in cosmetic formulations (below pH 7), and existing additives like non-ionic surfactants and alkoxylated carboxylic acid esters have drawbacks such as nitrosamine traces and 1,4-dioxane formation.
Innovation Solution
A composition comprising glycolipids, specifically rhamnolipids, glucolipids, and sophorolipids, combined with triethyl citrate, at a weight ratio of 5:1 to 20:1, and a pH of 4.5 to 7.0, enhances foaming properties and stability, particularly at acidic pH levels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional methods (heating, stirring, ultrasonic treatment, use of catalysts or solvents) are used to incorporate phospholipids into lipid particles, then phospholipid incorporation can be achieved, but the process becomes complex, requires additional equipment, and may cause phospholipid degradation
Solution Approach 1:
The invention extracts and eliminates the need for complex conventional methods (heating, stirring, ultrasonic treatment, catalysts, solvents) by using a novel spray drying approach that incorporates phospholipids into lipid particles without these additional processes, thereby simplifying the overall manufacturing process while maintaining reliable phospholipid incorporation
Solution Approach 2:
The invention uses spray drying as an intermediary process that enables phospholipid incorporation into lipid particles through a controlled atomization and rapid drying mechanism, avoiding the need for direct thermal or mechanical treatment that would require complex equipment and could degrade the phospholipids
2Reliability
If conventional methods are used to incorporate phospholipids into lipid particles, then phospholipid incorporation can be achieved, but phospholipid degradation occurs due to heat, mechanical stress, catalysts, or solvents
Solution Approach 1:
The invention converts the potential harm of heat and mechanical stress into a benefit by using controlled spray drying conditions where rapid atomization and immediate drying prevent degradation, while the brief exposure to heat actually facilitates efficient solvent removal and particle formation without damaging the phospholipids
Solution Approach 2:
The invention rushes through the phospholipid incorporation process in a single rapid spray drying step, minimizing the time phospholipids are exposed to potentially degrading conditions such as heat, mechanical stress, or chemical agents, thereby achieving incorporation while preventing degradation
3Reliability
If phospholipids are incorporated into lipid particles using conventional methods, then lipid particles can be formed, but the process is time-consuming and requires multiple steps
Solution Approach 1:
The invention merges multiple conventional steps (phospholipid dissolution, lipid particle formation, and phospholipid incorporation) into a single integrated spray drying process, where all components are mixed and processed together in one continuous operation, significantly reducing process time while ensuring reliable lipid particle formation with incorporated phospholipids
Solution Approach 2:
The invention performs preliminary mixing of phospholipids with the lipid mixture before spray drying, ensuring uniform distribution and readiness for immediate incorporation during the rapid drying process, which eliminates the need for subsequent incorporation steps and reduces overall process time
