KESMILD®-BTMS90 is a behentrimonium methosulfate conditioning ingredient for professional hair care manufacturing, supplied to cosmetic brands and manufacturers in bulk with customized packaging available. Formulators working on Hair Moisture goals and Damaged Hair Care briefs use it for deposition on negatively charged hair fibers, combability, static reduction and frizz control without a greasy residue. This guide covers the mechanism, selection criteria, granule handling and the specification path to a sample.
Before choosing an ingredient, it helps to know what damaged hair actually presents at the fiber surface. Four changes drive most moisture and combability complaints.
Repeated washing, heat styling and chemical services lift the overlapping cuticle scales, roughening the fiber surface and exposing the cortex underneath.
A lifted, worn cuticle leaves more negatively charged sites on the surface, increasing friction between fibers and making wet and dry combing harder.
Porous fibers take up and release water unevenly, so hair feels dry soon after washing and is more prone to breakage and roughness.
Dry, charged fibers repel one another, which shows up as flyaway, static and surface frizz — especially in low humidity or after towel drying.
The product page documents a five-step performance story for KESMILD®-BTMS90. Each step below is a decision point you can test in your own base.
As a cationic conditioning agent, KESMILD®-BTMS90 carries a positive charge that is drawn to the negatively charged surface of damaged hair.
The supplier states the ingredient promotes excellent deposition on negatively charged hair fibers, forming a conditioning layer along the fiber surface.
That deposited layer is linked to measurable improvements in wet and dry combability — the performance point most consumers notice first.
The page also cites a significant reduction of static electricity on hair surfaces, which supports anti-static claims and reduces flyaway.
Documented benefits include hair moisture retention and effective frizz control without leaving a greasy residue on the fiber.
Both chemistries appear in conditioning systems, and the product page confirms KESMILD®-BTMS90 is compatible with other conditioning agents, including behentrimonium chloride, allowing tailored product development. Use the table to run a fair comparison on your own base rather than on generic assumptions.
| Selection factor | How KESMILD®-BTMS90 is positioned | What to confirm before you decide |
|---|---|---|
| Conditioning character | Described as a mild cationic conditioning agent that improves hair softness, smoothness, detangling and combability. | Ask the supplier for the current positioning and documentation of the chloride grade you are evaluating. |
| Blend compatibility | Stated as compatible with other conditioning agents, including behentrimonium chloride, for tailored development. | Verify blend ratios and stability in your own base rather than assuming a fixed exchange rate between the two. |
| Supply form | Supplied as light yellow to white granules, which the page links to ease of handling and dosing accuracy. | Confirm the supply form and handling requirements of the grade you are quoted, and whether it suits your plant. |
| Damaged and dry hair briefs | Positioned for dry, rough or damaged-looking hair, with hair moisture retention and frizz control without residue. | Run head-to-head combability and sensory panels at equal conditioning load to see which reads better on your target hair type. |
| Process and scale-up | Page states physical and chemical stability under different processing conditions, supporting consistent batch-to-batch performance. | Confirm stability data against your process temperature, pH window and hold times before committing to a scale-up trial. |
| Documentation for claims | Request Product Details and download the available documents from the product page. | Request equivalent documentation for any alternative grade so your compliance file is complete either way. |
The granular supply form is one of the practical reasons formulators choose this grade for production-scale conditioning systems.
Pick the product format you are developing, then confirm the points in the right-hand column with the supplier before you lock a formula.
| Product format | What the formulation needs | How BTMS90 is positioned | What to confirm |
|---|---|---|---|
| Rinse-off conditioner | Everyday detangling, softness on damp hair and a light after-feel without buildup. | Listed for conditioners, with detangling, combability and static reduction claims. | Request a starting formula and the recommended addition level for your base. |
| Hair mask / intensive treatment | Stronger conditioning for dry or damaged-looking hair without a heavy or coated feel. | Listed for hair masks focused on hair softness and damaged hair care; effect described as perceptible without excessive buildup. | Check compatibility with the other conditioning agents and actives already in your base. |
| Leave-in treatment | Combability and frizz control that holds through the day, with no greasy residue. | Listed for leave-in treatments, contributing to hair moisture retention and frizz control without a greasy residue. | Assess sensory profile at your intended dose, especially on fine hair. |
| Shampoo / cleansing formulation | Conditioning performance inside a cleansing base without buildup over repeat use. | Used in shampoos and other haircare formulations where conditioning performance is required. | Confirm surfactant compatibility and stability in your cleansing system. |

A single conditioning agent rarely carries a whole product. These are the practical compatibility checks to run before you commit to a base.
The page confirms compatibility with other conditioning agents, including behentrimonium chloride, so a blend can be tuned to your sensory target.
Concentration can be optimized while maintaining product stability and sensory attributes — treat the level as a variable, not a fixed number.
Described as perceptible conditioning without excessive buildup, which suits products used several times a week on dry or damaged-looking hair.
Send your product format and target hair type, and the ingredient specialist can come back with recommended addition levels, a starting formula and the documentation you need for your compliance file.
Bulk supply and customized packaging are available, so state your intended batch volume and packing format in the first message.
