TLDR Optimal hair heat protectant spreadability is achieved with 4% shea butter and coconut oil, and 0.64% cetostearyl alcohol.
This study investigates the impact of lipid components on the spreadability of hair heat protectants, which is crucial for effective thermal protection. Using a central composite rotational design, the research analyzed the spreadability of formulations containing cetostearyl alcohol, shea butter, and coconut oil, with concentrations ranging from 0.64% to 7.36%. The results showed that spreadability was significantly influenced by the concentration of these components (p < 0.05). Optimal spreadability was achieved with 4% concentrations of shea butter and coconut oil and a low concentration of cetostearyl alcohol (0.64%). These findings suggest that the formulation of heat protectants can be optimized to ensure adequate coverage and protection of the hair shaft.
