Hydrophilic-Lipophilic Difference (HLD)

Improving Innovation for our customers through advanced and effective technical services

HLD (Hydrophilic Lipophilic Difference) is the next generation of surfactant science rapidly increasing in popularity across the industry. The model predicts the best surfactant for your system with little to no lab work required. If you’ve ever wondered why a product works in one system and not another, or been frustrated trying to make or break emulsions, HLD provides both the solutions and understanding.

At BASF we are experts in helping our customers apply this new technology to reduce development time and increase innovative output. Reducing surfactant behavior to the oil, temperature, and salinity of the system a few of the many ways we can help are:

  • Formulate completely stable emulsions
  • Reduce surfactant loading to form microemulsions
  • Predict how additives will effect the stability of your product
  • Separate both water in oil and oil in water emulsions
  • Create products that are completely insensitive to salt and temperature changes
