How to Use AccessQUAT STMS in Your Formulations

Understanding AccessQUAT STMS

If you want to create hair care products that make hair feel incredibly soft and easy to comb, you need a conditioning agent. AccessQUAT STMS is a powerful cationic (positively charged) conditioner that works like a magnet for your hair. Hair, especially when it’s dry or damaged, has a negative charge. The positive charge of AccessQUAT STMS allows it to bond to the hair shaft, smoothing down the cuticles to reduce frizz, eliminate static, and provide amazing slip.

This effect, known as substantivity, is what makes hair feel conditioned even after rinsing. It deposits a very thin, weightless film that detangles, softens, and adds shine. For formulators, this means you can create high‑performance conditioners, masks, and detanglers that rival professional salon products. It also functions as a co‑emulsifier, helping to create stable cream‑based conditioners.

Formulation Tips

Usage guidelines (as supplied): 0.5–2% for lightweight leave‑in conditioners or detangling sprays; 2–4% for daily rinse‑off conditioners; up to 5% for intensive masks or treatments targeting very damaged hair.

Add AccessQUAT STMS flakes or pellets to the water phase and heat to 70–75 °C (158–167 °F) with mixing until fully melted and dispersed. It is commonly paired with fatty alcohols (e.g., Cetyl or Cetearyl Alcohol) to build viscosity, enhance conditioning, and create a rich, stable cream base.

As a cationic ingredient, AccessQUAT STMS works best in conditioning systems or in cleansing conditioners alongside non‑ionic or amphoteric surfactants. Avoid high levels of strong anionic components (e.g., sulfate surfactants) that can reduce its performance.

Key Formulation Benefits:

Superior Detangling & Slip: Dramatically reduces combing force on wet and dry hair to minimize friction and breakage.
Effective Frizz & Static Control: Neutralizes negative charge on the hair surface to reduce flyaways and improve smoothness.
Silky Soft Hair Feel: Deposits a lightweight, conditioning film for exceptional softness without greasy residue or heavy build‑up.
Improves Hair Health & Shine: Smooths and helps seal the cuticle to protect the hair shaft, reduce the look of split ends, and enhance natural shine.
Versatile Co‑Emulsifier: Aids in emulsifying oils and fatty alcohols into water, supporting stable, elegant conditioner textures.

Frequently Asked Questions About AccessQUAT STMS

“Cationic” means it has a positive electrical charge. Hair carries a negative charge, so AccessQUAT STMS is attracted to it like a magnet. This attraction lets it deposit on the hair surface to smooth it down, reduce static, and deliver a soft, conditioned feel.

Use 0.5–2% for light, leave-in products (e.g., detangling sprays). For standard rinse-off conditioners, 2–4% is typical. For rich deep-conditioning masks, use up to 5%.

No. Steartrimonium Methosulfate is a gentle cationic conditioning agent and is not the same as anionic cleansing sulfates like SLS. It conditions; it does not cleanse or strip.

Add flakes/pellets to the water phase and heat to 70–75 °C (158–167 °F) with mixing until fully melted and uniform, then proceed with emulsification and cool-down.

It is most compatible with cationic, non-ionic, and amphoteric materials. High levels of strong anionic ingredients (e.g., sulfate surfactants or un-neutralized carbomer) can reduce performance—use with care or avoid.

Both AccessQUAT STMS and BTMS (Behentrimonium Methosulfate) are excellent cationic conditioners. Sensory feel and conditioning intensity may differ. BTMS is often sold pre-blended with fatty alcohol (e.g., BTMS-50), while AccessQUAT STMS is typically the standalone quat, giving you more control over fatty alcohol levels.
