CloSYS Sensitive Mouth Rinse — Alcohol-Free, pH-Balanced

CloSYS Ultra Sensitive Mouth Rinse by Rowpar Pharmaceuticals is an alcohol-free, pH-balanced oral rinse built around Cloralstan — a stabilized chlorine dioxide chemistry that is gentle on oral tissues. The rinse carries the ADA Seal of Acceptance and is widely used by dentists and hygienists for patients who need an effective everyday rinse without the burn of conventional alcohol-based mouthwashes.

Where most antiseptic mouthwashes mask odor with alcohol or strong flavoring, CloSYS works by neutralizing volatile sulfur compounds — the actual molecules that cause halitosis (bad breath). Because there is no alcohol and no harsh antiseptic compounds, the rinse does not sting, dry out tissues, or leave the burning sensation that many patients find intolerable.

CloSYS is well suited to:

• Post-surgical and post-extraction healing, when oral tissues are tender
• Dry-mouth (xerostomia) patients who can't tolerate alcohol-containing rinses
• Sensitive soft tissue (oral lichen planus, recurring canker sores, gum inflammation)
• Halitosis management — neutralizing odor at the source rather than masking it
• Daily oral care for patients who simply don't like the burn of conventional mouthwashes

To use, pour about 1 teaspoon (2 capfuls) into the cap, swish vigorously around the mouth for 30 seconds, then spit. Do not swallow. Twice daily after brushing is typical. There is no need to rinse with water afterward.

The Original formulation has a mild mint flavor; the Ultra Sensitive (Unflavored) formulation contains no flavoring at all and is the gentler option for patients with extreme sensitivity to flavoring agents or essential oils. Both are alcohol-free, sugar-free, and free of harsh antiseptic compounds.

Note: This version of CloSYS does not contain fluoride. Patients who need fluoride should continue using a fluoride toothpaste or rinse alongside CloSYS as advised by their dentist.

Frequently Asked Questions

Why use CloSYS instead of Listerine?

Conventional mouthwashes (such as Listerine) rely on alcohol and essential oils to kill bacteria, which produces a strong burn and can dry out oral tissues. CloSYS uses Cloralstan stabilized chlorine dioxide — alcohol-free and pH-balanced — to neutralize volatile sulfur compounds without the sting. It is a better fit for sensitive tissues, dry-mouth patients, and post-surgical healing.

Does CloSYS contain fluoride?

No. CloSYS is a chlorine-dioxide-based rinse for halitosis, sensitive tissue, and dry-mouth comfort — it does not contain fluoride. If you need fluoride for cavity prevention, continue your fluoride toothpaste or rinse alongside CloSYS as advised by your dentist.

How often can I use CloSYS?

Twice daily after brushing is typical. CloSYS is gentle enough for daily long-term use, including for patients with sensitive tissues, dry mouth, or recent oral surgery.
