C-Glycoside Cosmetic Viscosity Stabilization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Cosmetic compositions containing C-glycoside derivatives often experience a significant reduction in viscosity when introduced into aqueous formulations, leading to fluidification and difficulties in application on keratin materials, and conventional thickening agents are affected, resulting in unattractive and uncomfortable application experiences.
Innovation Solution
Incorporating an associative polymer into the cosmetic composition with a C-glycoside derivative maintains the viscosity, allowing for a suitable texture for application and providing a comfortable, pleasant experience, using specific types of anionic and non-ionic associative polymers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If C-glycoside derivatives are introduced into aqueous cosmetic formulation, then biological properties for combating epidermal aging and skin dryness are improved, but viscosity decreases significantly making application difficult
Solution Approach 1:
The patent uses associative polymers as intermediary substances that mediate between the C-glycoside derivative and the aqueous formulation. These polymers have dual affinity (hydrophilic and hydrophobic regions) that allow them to interact with both the glycoside molecules and water, forming a network structure that maintains viscosity while permitting the biological activity of the C-glycoside to function effectively
2Ease of operation
If conventional gelling agents are used to compensate for viscosity decrease, then viscosity is maintained, but the composition becomes too thick and leaves a white cast
Solution Approach 1:
The patent changes the fundamental parameters of the thickening mechanism by using associative polymers instead of conventional gelling agents. These polymers operate through different physical-chemical parameters (micelle formation, hydrophobic interactions) rather than the traditional hydrogen bonding networks of conventional thickeners, resulting in viscosity enhancement without the formation of opaque, heavy gels that cause white cast
Solution Approach 2:
The formulation creates a composite system combining C-glycoside derivatives with associative polymers in an aqueous medium. This composite structure allows the polymer network to provide thickening while the glycoside molecules remain dispersed and active, avoiding the phase separation or crystallization that causes white cast with conventional thickeners
3Ease of operation
If wax and fatty alcohol are added to compensate for viscosity loss, then viscosity increases, but the composition becomes difficult to spread and penetrate
Solution Approach 1:
The patent replaces heavy, persistent waxy structures with lightweight, dynamic associative polymer networks that provide temporary viscosity enhancement during application. These polymers are designed to be less substantial than waxes, allowing the formulation to be applied easily and penetrate quickly without the heavy, occlusive feel of wax-based thickeners

Function Achieved in This Case
The combination of C-glycoside derivatives with associative polymers ensures stable viscosity, enabling easy and precise application of cosmetic compositions on keratin materials while maintaining comfort and aesthetic appeal.
Implementation Method 1
Associative polymers are water-soluble polymers capable, in an aqueous environment, of reversibly associating with each other or with other molecules
