Clear Gel Sunscreen Formulation

Regarding your question about mixing SPF Protect Ultra™ II into Aloe Vera Gel (Heavy) to create a clear gel sunscreen without silicone:

SPF Protect Ultra™ II is an oil-soluble ingredient and requires heating to 70-80°C for proper mixing into a formula. Aloe Vera Gel (Heavy) is a water-based gel (oil-free).

Mixing an oil-soluble ingredient like SPF Protect Ultra™ II into a water-based gel will not result in a clear product. The mixture will become opaque, similar to an emulsion, because oil and water phases do not naturally mix clearly.

To achieve a clear gel sunscreen, you would typically need to use a sunscreen ingredient that is directly soluble in water and mix it into a water-based gel. Alternatively, you could create an entirely oil-based clear formula using an oil-soluble sunscreen, but this would likely feel greasy on the skin.

Please note that sunscreen formulas using water-soluble UV filters in a water base are generally not water-resistant and can be easily washed off by sweat or water.

Therefore, you cannot directly mix SPF Protect Ultra™ II into Aloe Vera Gel (Heavy) to achieve a clear gel sunscreen.
