Abstract: Guar hydroxypropyltrimonium chloride (GHPTC) is one of the most widely used cationic polymers in the personal care industry, employed primarily as a conditioning agent in shampoos and body washes. In many of these rinse-off products, it is also a critical deposition aid for the delivery of active ingredients and hydrophobic conditioning agents, e.g., silicones, to the skin and hair.

Market Data

  • Consumers are looking toward hair for anti-aging benefits.
  • Anti-aging hair care products address concerns such as thinning, coloring, breakage and drying, with emphasis on particular ingredients that target specific hair issues.
  • Although trends in anti-aging hair care are currently focused primarily in North America and Europe, hair care brands are seeing opportunities globally, including emerging markets.

Guar hydroxypropyltrimonium chloride (GHPTC) is one of the most widely used cationic polymers in the personal care industry. According to the US Food and Drug Administration’s Voluntary Cosmetic Registration Program (VCRP), the use of GHPTC has been documented in 751 products, ranking it third behind polyquaternium-10 (1,446 reported uses) and polyquaternium-7 (1,041 reported uses).1, 2 GHTPC is employed primarily as a conditioning agent in shampoos and body washes. In many of these rinse-off products, it is also a critical deposition aid for the delivery of active ingredients and hydrophobic conditioning agents, e.g., silicones, to the skin and hair.
