If you are adding salt to your soap, I would use just plain old table salt. I would be hesitant to add salt to coconut whip, it might affect the volume and deflate the whipped effect. You can make an emulsified salt scrub.

I wouldn't bother preserving the soap if it's solid.

If the body whip is a water-in-oil emulsion, it won't need preserving; if it's oil-in-water, it will.

We would need to know more about the deodorant to say. Does it have water in it?

If you are only using oils AND the product will not be exposed to water, you do not need a preservative. If you want to anyway make sure you choose one that is effective in anhydrous products.

ANY product made with both oil and water MUST have a preservative.

Not if it's w/o. Classic example: butter. If the water phase isn't continuous, microbes can't spread through it.

And even though a product be exposed to water, if the water doesn't form a liquid phase through it, it doesn't spoil. Take the example here of goat milk in the soap. The goat milk doesn't remain as a liquid, so no matter how many times the cake of soap gets wet, it won't spoil. OTOH gelatine, although it's a solid mass, has a liquid water phase in it, so it can spoil.

Regarding the issue of preservatives, the bottom line is bath and beauty products should be formulated for worst-case conditions, not laboratory ideals. Bar soap due to its solid nature and its relatively high pH is usually safe without a preservative, although some do add a preservative anyway.

But liquid soap and other fluid or emulsified products may have questionable safety without preservatives. Users can and do stick unsanitary wet fingers in a jar, add tap water to dilute the product, etc. If the product is contaminated or modified in this way, then product may not remain safe without preservatives, even though it is perfectly safe when supplied by the maker.

Best practice is to add a preservative to fluid or emulsified bath and beauty products. This is even more true if the products are sold to consumers rather than just made for personal use.
