Most adult hello rinses list cetylpyridinium chloride (CPC) as the primary active ingredient. The kids anticavity rinse lists sodium fluoride as its primary active ingredient.
Most adult hello mouthwashes are described as alcohol-free and fluoride-free. The kids anticavity rinse is also alcohol-free but contains fluoride (sodium fluoride) for cavity prevention.
Product descriptions highlight antiplaque and antigingivitis effects, cavity prevention for the kids rinse, fresh breath/bad-breath control, gum-health support, and moisturizing (non-drying) properties.
Many listings advertise formulas free from alcohol (adult variants), fluoride (most adult variants), artificial flavors and sweeteners, dyes, parabens, SLS, and gluten. Several items are labeled vegan and not tested on animals; some also mention phthalate-free and formaldehyde-donor-free claims.
Reviewers commonly praise the taste and a fresh/clean mouthfeel, note a non-drying sensation, and highlight alcohol-free and clean/vegan ingredient claims. A few reviews also mention good value and that some bottles yield relatively few uses.
The charcoal mouthwash includes a bottle-shaking instruction to mix the activated charcoal before use. Listings also note adult supervision for the kids rinse and warnings against use by very young children.
