Regarding Adding WaterGuard Ultra to Your Sunscreen Formula

Based on the information available, we could not find details about the specific products WaterGuard Lite and WaterGuard Ultra in our database. Therefore, we cannot provide precise guidance on whether adding WaterGuard Ultra to your existing formula containing WaterGuard Lite is compatible or how it might affect the stability and performance of your sunscreen, especially for increasing water resistance for swimming.

Adding ingredients to an existing, pre-made formula can be complex. It's not typically recommended to simply mix in additional ingredients without understanding the full formulation and the compatibility of all components. Doing so could potentially destabilize the emulsion, reduce the effectiveness of the UV filters, or alter the texture and feel of the product.

For optimal water resistance suitable for activities like swimming, it is best to use a sunscreen formula specifically designed and tested to be highly water-resistant.

Calculating 6% of WaterGuard Ultra in Grams

The weight of 6% WaterGuard Ultra in grams depends entirely on the total weight of your sunscreen formula. The percentage represents 6 grams of WaterGuard Ultra for every 100 grams of the total formula.

To calculate the exact amount in grams, you would use the following formula:

Weight of WaterGuard Ultra (grams) = (6 / 100) * Total weight of your formula (grams)

For example, if your sunscreen formula weighs 100 grams in total, 6% WaterGuard Ultra would be 6 grams. If your formula weighs 50 grams, 6% would be 3 grams.
