Foaming Bath Salt is more complicated to mix because of the dust factor. However, when its mixed, dust isn’t an issue.

The salt can be mixed in the bag or transferred to a larger bag or a bucket with a lid. The contents are not dangerous, but pour slowly.

CAUTION
Make sure that if this product is transferred to another container or shaken to mix color or fragrance, it should be done in a well ventilated area or preferably outside.

Step 1 Open the package by removing the label and unfolding.

Step 2 Mixing in the bag requires standing it up. Wait a minute till the next step.

Step 3 With scissors or a blade, open the bag.

Step 4 If you want color, add powdered pigments or liquid colors to the bag, using a teaspoon of either. Include fragrance to the bag, which at 0.25% or 1/2oz would be a good starting point. Adding anything over 0.5% or 1oz. will make the product wet, settle and clump.

Step 5 Without shaking, seal the bag or bucket. Ensure its well sealed because of the dust, then go somewhere well ventilated or outside. Shake well and roll contents around. In a few minutes it should be mixed.

Step 6 Let the contents sit for a minute before opening. If you want to add more scent or color, open the bag and repeat step #5.

Tips and Tricks
What container you put your product in has to be considered. Essential oils can interact with plastic and will soften the package over time. Pick a PET or PET-G plastic for clear products. Keep your eye on frosted bottles made with HDPE plastics. Your manufacturer or distributor can help you select the proper type. Fragrances are not known to have any adverse effect on plastics.

Colored salts can be tricky with clear containers. UV light can “bleach” or fade colors, with reds and blues being more pronounced. (UVA and UVB are red and blue light spectrums). Pigments work slightly better than FD&C colors, but still subject to fade a bit. If unsure,
- use colors without red or blue.
- keep out of direct light
- add additional color, then expose to sunlight to pre-fade them.
- minimize area of exposure with wrap around or frosted label
- add no color to salts and use color on your labels instead

Test and determine how much color to add for product stability. Like most things, don’t rush into something without a little trial and error.
