Bio-Concordant Personal Lubricant

Applied chemistry for intimate care.

Bio-Concordant Personal Lubricant is a patent-pending program in development at Soluda Labs. An aqueous lubricant designed to last, rinse away easily, and leave a dry finish.

The problem

Most personal lubricants rely on one of three chemistries, and each has a trade-off.

Many glycerin- and glycol-based gels have far higher osmolality than the body’s own fluids: often above 1,000 mOsm/kg (Cunha 2014), against about 370 for healthy vaginal fluid (Tyssen 2022).

Simple water-based gels dry quickly and turn tacky.

Silicone lasts, but it is not water-soluble, is hard to clean up, and should not be used with silicone wellness devices.

Our approach

An aqueous hydrogel lubricant designed to behave like the body’s natural fluids: to stay in place at rest, glide under motion, and last. It rinses away with water.

The formulation and its method of manufacture are the invention, both covered by our U.S. provisional application, with bench testing under way. We license it to intimate-care and sexual-wellness brands and provide optional consulting support.

Design goals

  • Designed to last like silicone and rinse like water.
  • Designed to stay put at rest and glide in motion.
  • Designed to match the body's own fluids.
  • Designed to stay smooth, never tacky or stringy.
  • Designed to be tuned to different textures and pH levels.
  • Designed to wash off easily with water.
  • Made without glycerin, silicone, or animal-derived ingredients.
  • Designed to be compatible with silicone wellness devices.

Potential applications

Every batch is made and tested in-house, for flow, texture, consistency, and compatibility with the body's own fluids.
