Question

Regarding the use of SepGEL 305:

If the formula contains Oil 5% and SepGEL 305 is used as the primary emulsifier and is the only one used, what percentage is recommended?

Are there any other ingredients recommended to add to help stabilize the formula?

Answer

Regarding the use of SepGEL 305 with 5% oil in your formula:

SepGEL 305 acts as both a primary emulsifier and thickener and can effectively emulsify up to 5% oil.

For a formula containing 5% oil, the recommended usage rate for SepGEL 305 is typically 1-2%. You can adjust the percentage up to 5% depending on the desired viscosity of your final product.

To ensure formula stability when using SepGEL 305, it is important to note that it does not tolerate electrolytes. Also, avoid over-blending (keep speed below 2500 rpm) as this can weaken the formula.

While SepGEL 305 can function as the sole emulsifier for 5% oil, the overall stability of the formula can also be influenced by other ingredients and the manufacturing process.
