Modified Hybrid Sunscreen Formula and Mixing Method
Question
How to formulate a modified hybrid sunscreen with Matte Silica? I have adjusted a hybrid sunscreen formula and would like to confirm if the following ingredients and mixing method are correct and compatible:
- Purified Water (75%)
- SPF Protect Ultra (20%)
- Satin Cream Maker (1%)
- Matte Silica (3%)
- Phenoxyethanol (1%)
My mixing method involves separating Matte Silica and mixing it with a portion of the water phase before combining it with the oil phase (SPF Protect Ultra) and the remaining water phase ingredients (Purified Water, Satin Cream Maker, Phenoxyethanol). Is this formula and mixing procedure appropriate?
Answer
Modified Hybrid Sunscreen Formula
Regarding your modified hybrid sunscreen formula and mixing method, based on the ingredients and the confirmation from our staff, your formula appears compatible and the mixing steps you described are correct.
Your formula includes:
- Purified Water (75%)
- SPF Protect Ultra (20%)
- Satin Cream Maker (1%)
- Matte Silica (3%)
- Phenoxyethanol (1%)
The total percentage is 100%, which is correct. The mixing method you described, where you separate the Matte Silica and mix it with the water phase before combining with the oil phase (SPF Protect Ultra) and other water phase ingredients (Purified Water, Satin Cream Maker, Phenoxyethanol), is a suitable approach for incorporating Matte Silica into an emulsion, especially one containing an oil phase. The Satin Cream Maker emulsifier is also compatible with this type of formula and oil percentage.
Therefore, your adjusted formula and mixing procedure are appropriate.
