Sustainable Multipurpose Hydrotrope Surfactant

Performant, 100% bio-based & readily biodegradable

In different applications such as detergency or oilfield that often involve high ionic media or extreme pH conditions, there is a need of boosting the surfactants efficacy with hydrotrope molecules while respecting the environmental concerns. The main hydrotrope offer is of petrochemical origin.
Pooling Formulation and Sugar-based chemical expertise, SEPPIC designed a 100% bio-based hydrotrope.

What is the function of a hydrotrope?

Hydrotropes are ingredients that improve the solubility of organic compounds in aqueous solutions. They are used to formulate concentrated combinations of surfactants with salts and diverse additives that durably stay homogeneous.

From sourcing to end of life

What makes SIMULSOL™ SL 7G innovative as a hydrotope surfactant:

  • 100% Bio-based. From a non ionic glucolipid structure, the surfactant is produced using glucose from starch origin and heptanol from non GMO Castor oil source
  • Manufacturing process fully compliant with the principles of green chemistry
  • Compatible with cold processes formulations
  • Readily biodegradability and no ecotoxicity (that limit the environmental impact)

This innovative Heptylglucoside surfactant received the Pierre Potier Award in 2013, by the Ministry of Economics, Industry and Employment in the presence of Arnaud Montebourg, the Minister of Industrial Renewal. Each year, the Pierre Potier Award singles out the best innovations in the chemical industry that promote sustainable development.

High hydrotropic performance

Thanks to its liquid appearance and high surfactant concentration, the Heptylglucoside hydrotrope surfactant combines performance and ease of use, even at cold temperature.


  • Soluble in cold water
  • Solubility not affected by temperature, no cloud point

Broad hydrotropic performance

  • Efficient with acids, alkalines and builders at lower dosage than benchmarks
  • Efficient even in extreme pH conditions, from 1 to 14, structure resistant to hydrolysis
  • Low foam properties, does not affect the formulation’s foaming properties
  • Compatible with all types of surfactants: anionics, amphoterics or cationics
