Kostol TMC-25 is a plant based, cationic oil-in-water emulsifier designed for both hair and skin care formulation. Developing emulsions with cationic systems offers better adhesion to hair and skin. In hair care, it will also provide conditioning, detangling, static control and frizz reduction. In skin care, this emulsifier offers skin conditioning with a silky, non-greasy after-feel. In each case, Kostol TMC-25 will emulsify and thicken your system. This is a 25% active quaternary ammonium compound that forms mild cationic emulsions.

Kostol TMC-25 is unique as it has been created without volatile materials like other behentrimonium chloride emulsifiers you may find on the market. The removal of flammable and volatile content ensures safety in the lab, production, and reduces regulatory issues for markets that prohibit these additives.

Kostol TMC-25 is a versatile emulsifier that can be used in both hair and skin care for leave-on and wash-off applications including the following:

There are some key points to remember when formulating with cationic emulsifiers. Cationic chemistry is typically incompatible with anionic products. They are characteristically not compatible with certain acrylate copolymers, xanthan gums and CMC thickeners as well as other anionic products. Keep in mind the active content as you formulate both leave-on and wash-off products and coordinate with your regulatory team for the rules based on the country of distribution.

Suggested Use Levels
Wash-Off Systems: 2.0 – 10.0%
Leave-On Systems: 0.5 – 8.0%

Formula: #2/20-10013/358-4

• Intense, sulfate-free conditioning mask
• With Orange Wax for emolliency and shine
• Leaves hair soft, supple and shiny

Procedure

• Begin heating water to 80 °C and add Phase A ingredients one by one, mixing each until uniform.
• Combine Phase B ingredients, and heat to 80 – 85 °C until melted.
• Add Phase B to Phase A under agitation and mix at high speed until emulsion is uniform.
• Check pH and adjust to 4-5 as necessary.
• Cool to 45 °C or under and pour into containers.

Stability information: Three months at 45 °C, three months at room temperature, three freeze/thaw cycles.

Formulators who need to replace a cationic conditioner for an approved INCI nomenclature can count on Koster Keunen. Using Kostol TMC-25 supports marketing requirements on the INCI declaration, without substantial changes to your formulation or its performance. Our laboratory results show that 1:1 replacement in all tested formulas, were equivalent in rheology profiles and performance.

Laboratory evaluations show that in multiple formulations, Kostol TMC-25 (Behentrimonium Chloride) is equivalent when replacing Behentrimonium Methosulfate in formulas at a 1:1 ratio.

Koster Keunen’s’ research team evaluated other cationic systems to compare them with Kostol TMC-25. A laboratory study done on TMC-25 vs other cationic emulsifiers show Kostol TMC-25 does not contain IPA or other volatile materials that are found in other similarly manufactured industry options. The proprietary process to remove volatiles materials allows for better safety in the laboratory and production. Laboratory evaluations also show in multiple formulations, Kostol TMC-25 is functionally equivalent without the volatile to other products with the same INCI name.
