Using Sucrose Palmitate (HLB 16) as Main Emulsifier for O/W Emulsion: Temperature and Ratio

Sucrose Palmitate (HLB 16) can indeed be used as a main emulsifier for an oil-in-water (O/W) emulsion. Its HLB value of approximately 16 is well-suited for this type of emulsion, and the product description confirms its role as an emulsifier.

Regarding the heating temperature for both the water and oil phases, the product description indicates that Sucrose Palmitate "can tolerate heat well" and that "high heat is required" for it to be dispersed in oil. While a precise temperature isn't specified, it is generally recommended to heat both the oil and water phases to a temperature between 70-80°C. This range ensures proper melting and dispersion of the emulsifier in the oil phase and facilitates stable emulsification.

For the optimal starting ratio of emulsifier to oil, the product description provides a general usage rate of 0.1-3.0% for the overall formulation. However, achieving a stable O/W emulsion requires calculating the Required HLB (RHLB) of your specific oil phase. Therefore, the exact ratio of emulsifier to oil will depend on your formulation. You can start with a concentration within the recommended usage rate and adjust based on the stability and characteristics of your emulsion.
