There are many reasons why you should consider using potassium thioglycolate as an ingredient in hair formulation:
In mousse product types, 4% to 6% levels provide the best hair removal performances. Their light foam nature demands lower percentages to perform well. The percentages maintain mousses light yet still provide stable performance.
The levels in creams is typically 5% to 8% and is determined by the cream base. Creams can accommodate higher levels since the thicker base minimizes irritation. The level provides stable performance without making the cream harsh and rigid.
When used as a spray ingredient, 5 to 7% levels are sufficient to offer adequate reactivity with good application properties that are safe. The amount dissolves keratin rapidly and maintains the liquid product stable. The range also stabilizes sprays in use.
