Question

1. Emily is making more soaps this Sunday.

2. Emily is making more soap this Sunday.
3. This is for shampoos, soaps and toothpaste.
[Which one is correct? Can we use 'soaps' as in #1? is 'soaps' right in #3?]

Answer 1

In this context, if Emily is making one batch of soap for use in other products, it would be singular, "soap". Number three is correct if she is making the soap for use in several products (more than one soap product as well as shampoos and toothpaste, the plural is correct. I do recommend the Oxford comma, though: shampoos, soaps, and toothpaste.
