Sunscreen Alternatives for Odor Issues

It sounds like you're having trouble with the odor of SPF Protect Ultra™ II, even when using Odor-Kill. This can happen with some chemical sunscreen ingredients or the solvents used in blends.

Here are a few alternative sunscreen options you might consider that could potentially have less odor:

• Pure Physical Sunscreen (SPF50+, PA3+, Water-in-Oil, Non-White): This is a ready-to-use base utilizing physical filters (Zinc Oxide and Titanium Dioxide). Physical sunscreens are mineral-based and generally odorless. This base is also noted as having no added scents, making it a strong candidate if odor is your primary concern.
• BEMT (Bis-Ethylhexyloxyphenol Methoxyphenyl Triazine, e.q. Tinosorb S): A high-performance chemical filter. It is supplied as a powder, which often has less inherent odor compared to liquid blends. However, it requires proper formulation to dissolve it in suitable solvents.
• SPF Protect Ultra™ III (UVA+UVB): This is a related product to SPF Protect Ultra™ II. While it is also a blend of chemical filters and might still have some odor, its composition could be different, potentially resulting in a different or less noticeable smell than version II.

The odor in chemical sunscreens can come from the active filters themselves or the carriers/solvents. Switching to a different type of sunscreen, like a physical one, or a different chemical filter/blend, can help mitigate this issue. While Odor-Kill helps, it may not completely mask a strong inherent odor from the raw material, especially at higher concentrations.

Consider the Pure Physical Sunscreen base as a primary option for its likely low odor profile and ease of use, or BEMT if you prefer a high-performance chemical filter and are comfortable with formulating from a powder.
