Croda Beauty has published fresh data about the efficacy of its Crodabond CSN hair repair active ingredient.
This new data highlights that 1% Crodabond CSN achieves an optimal balance between effective split end repair and a desirable, natural sensory feel.
Launched last year, Crodabond CSN (INCI name: Hydrogenated Castor Oil/Sebacic Acid Copolymer) has gained recognition for its wash-resistant cuticle sealing and split end repair, as well as its ability to enhance smoothness and shine.
Building on its proven track record, Croda Beauty conducted Scanning Electron Microscopy (SEM) imaging studies to investigate the performance of 2% Crodabond CSN in a leave-on serum.
The test formulation was compared to a placebo formulation and a leading commercial benchmark containing another natural split end repair active, and these were tested on type 1 (European) hair.
The results were compelling – Crodabond CSN sealed more split ends than the placebo and demonstrated superior wash-out resistance compared to the benchmark.
Further testing on type 1 (Asian) hair delivered equally impressive results. Dan Chan, hair care scientist based in Croda Singapore, shared her observations:
“The results for Asian hair aligned with the positive trends observed previously, with Crodabond CSN outperforming the placebo in split-end sealing. The benchmark in this study—a leading commercial split end repair formulation from the Asian market featuring a synthetic active—demonstrated effective sealing but lacked natural credentials,” the company said.
“Crodabond CSN, while slightly less long-lasting than the benchmark, provides split end repair alongside the added benefit of naturalness.
“Also, a study at a lower concentration of 1%, compared to the previous 2%, confirmed the ingredient’s efficacy at reduced use levels. To achieve the optimal balance of performance and natural sensory appeal, we recommend incorporating 1% Crodabond CSN in leave-on systems”.
