How to Use AccessQUAT STAC80(I) in Your Formulations

Understanding AccessQUAT STAC80(I)

If you’ve ever struggled with tangled, frizzy, or static-prone hair, a cationic conditioning agent like AccessQUAT STAC80(I) is the solution. Think of it like a magnet for damaged hair. Hair, especially when damaged, carries a negative electrical charge. AccessQUAT STAC80(I) has a positive charge (which is what “cationic” means), so it’s naturally drawn to the hair fiber. It forms a very fine, conditioning film on the surface of the hair, smoothing down the rough, lifted cuticles.

This action is what provides the amazing slip that allows you to effortlessly detangle knots, and it’s what makes hair feel so soft and smooth after conditioning. For the more technical formulator, this ingredient, Steartrimonium Chloride, is a quaternary ammonium compound (“quat”) prized for its high substantivity to hair, leading to reduced inter-fiber friction and a significant decrease in combing force. It effectively neutralizes static charges, which is essential for preventing flyaways, especially in dry weather.

Formulation Tips

For best results, use AccessQUAT STAC80(I) at a concentration of 0.2% to 2.5%. For lightweight leave-in conditioners or detangling sprays, stay in the 0.2–1% range. For daily rinse-off conditioners, 1–2% is a great starting point. For intensive deep conditioning masks or repair treatments, you can use up to 2.5%.

Here’s how to incorporate it into your formula: AccessQUAT STAC80(I) should be added to your water phase. Heat the water to around 75°C (167°F) and add the ingredient, stirring until it is completely dissolved and the liquid is clear. It works wonderfully when combined with fatty alcohols like Cetyl Alcohol or Cetearyl Alcohol, which act as thickeners and co-emulsifiers to create a rich, creamy final product.

A critical tip for formulators: as a cationic ingredient, AccessQUAT STAC80(I) can be incompatible with strong anionic (negatively charged) ingredients. Avoid mixing directly with high concentrations of anionic surfactants like Sodium Lauryl Sulfate (SLS). It works best in conditioner formulas or with non-ionic, amphoteric, or other cationic ingredients. It is most effective and stable in formulations with a slightly acidic pH (typically between 4.0 and 6.0), which is ideal for hair care.
