Solution Approach 1:

The patent changes the chemical composition parameters by introducing a specific polyamine polymer with defined molecular weight (1000-10000 g/mol) and structure (containing amino groups and hydroxyl groups). This parameter change reduces viscosity from conventional high levels to below 5000 cP at 25°C, enabling easier processing and lower energy consumption during manufacturing while maintaining surfactant performance

Inventive Principle:
