Adenosine Phosphate O/W Emulsion Composition for High Viscosity Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing O/W emulsion compositions containing adenosine phosphate and acrylic acid-alkyl methacrylate copolymer struggle with achieving high viscosity (≥10,000 mPa·s) while maintaining good emulsification stability.
Innovation Solution
Incorporating specific water-soluble polymers, such as urethane associative thickeners, and pH adjusters, along with uncrystallized high melting point oils and oil-based gelling agents, to enhance emulsification stability and improve the feel during use.

1Force
If adenosine phosphate and acrylic acid-alkyl methacrylate copolymer are used to create high viscosity O/W emulsion, then viscosity increases to ≥10,000 mPa·s, but emulsification stability deteriorates
Solution Approach 1:
The patent introduces a specific intermediary substance (polyglyceryl-3 distearate) as a mediator between the adenosine phosphate/acrylic acid-alkyl methacrylate copolymer system and the emulsion droplets. This intermediary substance acts as a bridge that maintains emulsification stability while allowing the high viscosity characteristics to be preserved, directly resolving the contradiction between viscosity and emulsification stability
Solution Approach 2:
The patent creates a composite emulsion system by combining multiple ingredients with complementary functions: adenosine phosphate for moisturizing, acrylic acid-alkyl methacrylate copolymer for viscosity and emulsion formation, and polyglyceryl-3 distearate for stabilizing the emulsion interface. This composite approach allows the system to achieve high viscosity while maintaining emulsification stability through the synergistic interaction of components
