Sunscreen Formulation: Oil Control, SPF 50+++, Skin Nourishment & Cold Process

Hello! The formula you proposed seems suitable for your needs: a facial sunscreen that absorbs oil, is non-whitening, provides SPF 50+++, includes some skin-nourishing ingredients, and has a rose scent.

Ingredients:

• The total percentages seem correct, summing to 100% for the formula using 20% SPF Protect Ultra II. If you wish to use 15% SPF Protect Ultra II as recommended by the staff for daily use, please adjust the Rose Water to 75.4% to total 100%.
• SPF Protect Ultra II is a good sunscreen base for high SPF. The staff recommends starting at 15% for daily use, while 20% is suitable for strong sun exposure and might require considering an additional emulsifier helper.
• MatteSilica XL™ or RiceSorb™ are effective for oil absorption.
• Skin-nourishing ingredients like Aloe Vera Extract, Ectoine, and Hi-EGCG™ provide beneficial properties for the skin. Although the staff generally advises focusing on sun protection efficacy and lightness in sunscreen formulas, these ingredients can be included to add value.
• Light Cream Maker is a suitable emulsifier for a light cream texture.
• Rose Water provides the rose scent and forms the water phase. According to the information provided, if Rose Water is used as the main component exceeding 60%, adding an additional preservative might not be necessary.

Mixing Steps:

• The cold process mixing steps you described are correct and similar to the method previously confirmed by the staff.

Adding More Extracts:

• Based on the staff's advice in the previous thread, adding more skin-nourishing ingredients to a sunscreen formula should be carefully considered, as it might make the texture heavier and potentially reduce sun protection efficacy. Your current formula already includes some beneficial ingredients, which should be sufficient. Adding other extracts might not be necessary and could affect the texture and stability of the formula.
