Hair Conditioner Formulation: Addressing Separation, Texture, and Bubbles

Based on the feedback regarding your hair conditioner formulation issues:

• Separation: The separation after about a week, accompanied by bubble formation, suggests a potential issue with the stability or emulsification of the formula. The staff recommends adding Butter Cream Maker (2%) to improve stability. It should be heated to 70°C and mixed with the oil phase ingredients (CTAC, BTAC, Cetyl Alcohol).
• Desired Texture (Thick but not sticky/viscous): To achieve a texture that is thick but still easy to bottle, the staff advises replacing Cetyl Alcohol with Shea Butter. Shea Butter has a minimal effect on viscosity. Adding Glyceryl Steearate SE is not recommended as it will increase thickness.
• Reducing Bubbles: If you are not using a vacuum mixer, incorporating an oil (like Shea Butter) or a Silicone (such as Dimethicone Light, Low-Odor at 5%) can help reduce the formation of small bubbles.
• Mixing Speed: The staff clarified that mixing speed does not control the final viscosity; this is determined by the ingredients in your formula. Adjusting the formula composition is the correct way to achieve the desired thickness.
• Adding CTAC Later: You can add CTAC later in the process (around 40°C) instead of heating it initially. This can help achieve your preferred texture, but ensure thorough mixing to ensure it dissolves completely.
• Willow Bark Extract: Adding Willow Bark Extract is compatible with this type of formula. Add it to the water phase, avoiding high heat, ideally during the cooling phase (around 40°C) while mixing.
