James Robinson Speciality Ingredients (JRSI) has launched Jarocare R25, a natural bond repair solution derived from red lentil protein.
Developed by the company's Biotome division, this innovative ingredient represents a shift in how damaged hair can be repaired.
The science behind R25 centres on its distinctive solvent-free enzymatic extraction process that preserves essential amino acids – lysine, arginine, and histidine.
This gentle approach stands apart from conventional harsh hydrolysis methods common in the industry, which often compromise the very elements responsible for restoration.
These preserved amino acids are what effectively repair broken bonds within the hair structure. Comprehensive testing confirms R25's effectiveness in repairing damaged hair.
Tensile strength (Dia-Stron) and Differential Scanning Calorimetry analysis reveals significant improvement in hair strength – up to 25%, surpassing the consumer gold standard in the category.
Advanced fluorescent tagging techniques provide visual confirmation that R25 penetrates deep into the hair fibre, reaching areas where repair is most needed.
As a COSMOS-approved ingredient, Jarocare R25 meets the highest standards for natural and organic cosmetics, while its readily biodegradable profile ensures minimal environmental impact.
These credentials, combined with its performance benefits, make R25 an ideal solution for brands committed to both efficacy and sustainability.
“Jarocare R25 represents years of research into plant protein chemistry and hair science,” said Dr. Daniel Brown, Research & Technology Manager at JRSI's Biotome division. “Our main goal was to create something that worked and delivered performance.
“The breakthrough came when we developed our own enzymatic method that maintains the functional integrity of key amino acids. This precision approach not only delivers superior bond repair but aligns perfectly with our commitment to sustainable chemistry.”
