Cosmetic Gel Transparency and Hardness via Glycerol Ester
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional transparent cosmetic preparations face issues with low hardness and poor usability due to the need for high-temperature heating, which can damage the oil-based components, and existing gelling agents fail to achieve both high transparency and hardness simultaneously.
Innovation Solution
A cosmetic transparent gel preparation combining 12-hydroxystearic acid with an esterification reaction product, such as those obtained from reacting glycerol with behenic acid, isostearic acid, or eicosanedioic acid, along with an oil component, to achieve a balanced ratio that enhances transparency and hardness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If cellulose derivative or dextrin fatty acid ester is added to 12-hydroxystearic acid to improve transparency, then transparency is improved, but high-temperature heating (95°C or higher) is required which damages the oil-based component quality
Solution Approach 1:
The invention changes the temperature parameter from 95°C or higher to 60-90°C by introducing a new gelling agent composition containing glycerol ester and polyethylene glycol, which has a lower melting point and dissolves at milder temperatures, thereby preventing damage to the oil-based component while maintaining transparency
Solution Approach 2:
The invention uses a composite gelling agent system combining glycerol ester (specifically glycerol monostearate or glycerol distearate) with polyethylene glycol in a specific ratio (glycerol ester 30-70 wt%, polyethylene glycol 30-70 wt%), where the two components work synergistically to achieve both transparency and gentle processing conditions
2Illumination intensity
If conventional gelling agents are used to achieve transparency, then transparency is improved, but hardness level becomes low
Solution Approach 1:
The invention creates a composite gelling agent system where glycerol ester provides the gel structure for hardness while polyethylene glycol ensures transparency, with the specific weight ratio (both 30-70 wt%) optimizing the balance between these two properties
Solution Approach 2:
The invention optimizes the molecular weight parameter of polyethylene glycol (400-20,000) to achieve the right balance between transparency and gel strength, where lower molecular weights improve transparency while higher molecular weights enhance hardness
3Stability of the object's composition
If high-temperature heating is applied to dissolve cellulose derivative or dextrin fatty acid ester, then dissolution is achieved, but localized heating occurs which increases adverse effects on quality
Solution Approach 1:
The invention changes the temperature parameter from 95°C or higher to 60-90°C by using glycerol ester and polyethylene glycol as gelling agents, which dissolve at lower temperatures, thereby eliminating localized heating damage while achieving complete dissolution and homogeneity
