Night Cream Formulation: Liquid Texture due to Electrolyte Incompatibility

Hello,

Regarding the night cream formula you inquired about, the team has reviewed it and would like to provide the following recommendations:

Reason for the formula being liquid instead of a cream:

As the staff explained in the thread, the main reason your formula turned out liquid is due to the incompatibility between Sodium Lactate Plus, which is an electrolyte, and Satin Cream Maker, which you used, as it cannot tolerate electrolytes well. This prevents the formation of the desired cream texture.

Other factors you noted, such as mixing time or the order of adding ingredients, can generally affect emulsion stability, but in this case, the primary issue stems from the incompatibility of the two main ingredients mentioned.

Solutions:

1. For making a new batch:

   • For beginners: It is recommended to remove Sodium Lactate Plus from the formula.
   • If you have experience: You can switch from using Satin Cream Maker to another Cream Maker or Gel Maker that can tolerate electrolytes. Examples include Butter Cream Maker (which requires heat for mixing) or an electrolyte-tolerant Gel Maker like AnyGel.

2. For the batch that is already liquid:

   • You can fix it by adding an electrolyte-tolerant Cream Maker or Gel Maker (as exemplified above) to the liquid formula and re-emulsifying it by blending or stirring (heat may be required depending on the chosen Cream Maker).

Can the liquid formula still be used?

A formula that has become liquid and separated can still be used. You should shake it to combine the ingredients before each application (the formula will stay combined for a short time after shaking, so apply it immediately).

We hope this information is helpful in improving your formula. If you have any further questions, please feel free to ask.
