Preventing Separation in Gel Formulation with High Oil Content
คำถาม
I have a gel formulation containing Fractionated Coconut Oil 10%, shea butter water 5%, and thickened with Pro Polymer. I want to add Lavender Fragrance Oil 1% and LastFix 10%. I am concerned about the formula separating. How can I prevent this separation?
คำตอบ
Regarding mixing fragrance into 100g of face cream base:
Based on your requested percentages:
- Lavender Fragrance Oil: 1% of 100g = 1g
- LastFix: 10% of 100g = 10g
You can add 1g of Lavender Fragrance Oil and 10g of LastFix directly into the 100g cream base and blend thoroughly until fully incorporated.
Regarding your specific gel formula and the concern about separation:
The staff's reply indicates that your formula already contains a significant amount of oil (Fractionated Coconut Oil 10% + Shea Butter Water 5% + potentially others). The thickener you are using, Pro Polymer, can only effectively suspend oils up to a maximum of 10% of the total formula.
Adding 1% Lavender Fragrance Oil and 10% LastFix (which are oil-based) will increase the total oil content well beyond the 10% limit that Pro Polymer can handle on its own. Therefore, there is a high probability of separation occurring in this specific gel formula if you add the fragrance and LastFix at these percentages without further modification.
The staff recommended adding Satin Cream Maker at 1% to your gel formula. Satin Cream Maker is an emulsifier that can help to effectively blend and stabilize a higher oil content, significantly reducing the chance of separation when adding the fragrance and LastFix.
