Kostol IBT is a plant-based, cationic emulsifier designed for both hair and skincare formulations. Developing emulsions with cationic systems offer better adhesion to hair and skin. In haircare, Kostol IBT will also provide significant conditioning, detangling, static control, and frizz reduction. In skin care, you will find skin conditioning with a silky, non-greasy after-feel. The chemistry of this emulsifier is a blend of behentrimonium methosulfate and Cetearyl alcohol with a 25% active level. This mainstream emulsifier is manufactured at our facility in Watertown Connecticut. This is a cationic oil-in-water emulsifier that is PEG-Free. It can emulsify in systems with a pH range of 2-11 and the typical usage level is 2-8% however more can be used. The recommended ratio of emulsifier to oil is one to four (1:4) to ensure the proper proportions and balance of the system. The sensory profile of an emulsion made with Kostol IBT is a medium emulsion break with medium absorption. These lotions have a typical dry and powdery after-feel that is common with cationic emulsifiers. Bouncy emulsions can also be made, and formulas using Kostol IBT are flexible in texture and viscosity with the right coordinating ingredients. Application options are versatile and include hair conditioners, shampoos, detanglers, bleaches, colorants, styling, masks, and treatments. In skincare, all emulsions, shave products, and skincare products can be made. 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. The Koster Keunen formulation team has created many personal care formulas including a range of hair conditioners, masks, and treatments along with skincare and shave products.
This chemistry along with sister products are used in a wide range of hair care products already in the market due to the ease of formulation and high conditioning factors. A simple conditioner can be made with 3% of Kostol IBT, additional additives of the formulator’s choice, fragrance, and preservative for a ready-to-go hair conditioner product. The higher the percentage of the cationic emulsifier, the more conditioning results.
