Formulating Clear, Smooth Deodorant Stick with Sodium Stearate
Question
Seeking advice on formulating a clear, smooth deodorant stick using Sodium Stearate as the gelling agent. The formula contains water, humectants, approximately 8% fragrance, and 5.5% other oils. What emulsifiers or dispersing agents can be used to effectively incorporate the oil and fragrance phases to achieve clarity and a smooth texture?
Answer
Deodorant Stick Formulation with Sodium Stearate
To create a clear, smooth deodorant stick using Sodium Stearate with water, humectants, 8% fragrance, and 5.5% other oils, Sodium Stearate acts as the primary gelling agent.
Achieving clarity and smoothness in a system containing both water and oil/fragrance phases requires careful formulation. While Sodium Stearate forms the gel structure, incorporating the oil and fragrance phases smoothly is crucial for clarity and preventing cloudiness or separation.
Ingredients that can help emulsify or disperse the oil and fragrance uniformly throughout the water-based gel matrix are beneficial. Emulsifiers like Sorbitan Stearate or Sucrose Stearate could potentially aid in blending the oil and fragrance components into the Sodium Stearate gel base, contributing to a more homogeneous and potentially clearer stick.
Ultimately, the clarity and smoothness will depend on the precise ratio of Sodium Stearate to the water and humectant phases, the effective incorporation of the oil and fragrance (possibly with the help of emulsifiers), and the manufacturing process, including heating and cooling rates.
