Alcohol-free mouthwash OEM/ODM manufacturing
Alcohol-Free Mouthwash · Gentle Mouth Rinse · OEM/ODM
Many people give up mouthwash because of the burning sensation and dry mouth after rinsing — mostly caused by alcohol. An alcohol-free mouthwash solves that, but removing alcohol also removes the solvent that dissolves essential oils and part of the preservation capacity. An alcohol-free formula therefore needs a good solubilizer system to keep the solution clear, a thoroughly challenge-tested preservative system, and a rebalanced flavor that still feels clean and fresh without being harsh. This line suits people who prefer a mild taste, daily users and the whole family. Butter-C offers full-service OEM/ODM manufacturing, from formula to a labeled finished product with its cosmetic product notification.
Formula base
An alcohol-free aqueous base with solubilizers and a robust preservative system
Without alcohol, the base needs added polyols and non-ionic solubilizers to keep flavor and essential oils clearly dissolved and to give a smooth mouthfeel.
Polyols
Glycerin, propylene glycol, sorbitol or xylitol — retain moisture, add a light sweetness and support solubilization.
Solubilizers
Poloxamer, PEG-40 hydrogenated castor oil, polysorbates — keep the solution clear.
Actives
Zinc salts and CPC for fresh breath; sodium fluoride for cavity-prevention lines; herbal extracts.
Preservation
Sodium benzoate and potassium sorbate at a suitable pH; verified by a preservative efficacy (challenge) test.
Key technical points
Four things that determine alcohol-free mouthwash quality
Keeping the solution clear
The amount of flavor and essential oil must match the solubilizer's capacity; cold-temperature testing detects haze early.
Preservation without relying on alcohol
Choosing a suitable pH and preservatives, with microbial challenge testing on the final formula itself.
Cool without burning
Low doses of menthol and cooling flavors, with the option of a low-odor cooling agent.
Masking zinc and CPC taste
Sweeteners and flavors are combined for a clean aftertaste without bitterness or astringency.
Three formulation directions
Three common alcohol-free mouthwash lines
Mild everyday mint
CPC or zinc, light mint, colorless; the core line for the whole family.
Herbal
Betel leaf, green tea, low-dose clove; natural color, a warm, mild taste.
Fluoride for adults and children over 6
Sodium fluoride, fruit or mild mint flavor; the label states not for use by children under 6.
Packaging designed alongside the formula
PET bottles with measuring caps, travel bottles, single-use sachets; no flammable-goods storage requirements as with alcohol-based lines.
