Why Has 'Bresmile Wash' Been Chosen for Five Consecutive Years?

'Bresmile Wash' is a liquid toothpaste that, simply by swishing in the mouth, binds to and rinses away oral impurities—such as protein-based residues that cause bad breath—that brushing alone cannot fully remove.

Total Oral Care Designed to Be Used with Brushing

Beyond cleansing the mouth through rinsing, Bresmile Wash offers multi-functional benefits in a single product: preventing periodontal disease, eliminating bad breath, and—when used alongside brushing—whitening effects through stain removal.

'9-Free' Formula for Daily, Comfortable Use

'Bresmile Wash' achieves a '9-Free*' formula, avoiding nine commonly concerning ingredients such as bleach and silicones. Manufactured under strict quality control at an ISO9001-certified domestic facility, it provides peace of mind for daily oral care routines.

*No bleach, mineral oil, synthetic dyes, silicones, UV absorbers, sulfates, synthetic antioxidants, artificial sweeteners, or petroleum-based surfactants

Major Upgrade to '3rd Generation' for Even More Advanced Care (May 12, 2026)

To deliver easier yet more effective oral care, 'Bresmile Wash' has been renewed on May 12, 2026.

Japan-First* Inclusion of Four Active Ingredients for E-Commerce Liquid Toothpaste

One product comprehensively addresses adult oral concerns—from bad breath prevention and stain removal (e.g., tobacco tar)—to periodontal disease prevention.

*Survey by Minato Corporation

Shining Nano-Capsule Ingredients Increased to 22 Types!

Ingredients that improve oral conditions, such as Centella Asiatica Extract (CICA)*, have been significantly increased from 10 to 22 types. Thanks to proprietary technology that miniaturizes ingredients, they thoroughly reach the crevices and uneven surfaces of teeth.

*Purpose: Humectant

'Neo Clean System' for a Healthier, More Resilient Oral Environment

Social Tech's exclusive 'Neo Clean System' (patent pending), which combines three ingredients including cherry blossom-derived yeast extract, leverages the power of biotechnology and herbal ingredients to create a more balanced and resilient oral environment.

Smooth, Shiny Teeth with Moisturizing & W-Coating

Three new 'moisturizing ingredients※1' to prevent dry mouth and 'W-Coating ingredients※2' to prevent re-attachment of stains have been added. This formulation delivers hydration, prevents dryness, and helps achieve smooth, glossy, and naturally white teeth.

※1 Placenta Extract, Hydrolyzed Eggshell Membrane, Hydrolyzed Conchiolin Liquid (Purpose: Humectant)

※2 Sodium Polyphosphate (Purpose: Cleansing Agent), Sodium Metaphosphate (Purpose: Chelating Agent)

New Packaging for Easier Handling and Pouring

The proprietary aluminum spout pouch has been further improved for better grip and ease of pouring.

Future Outlook

Social Tech will continue to expand its innovative product lineup in response to evolving customer lifestyles, contributing to more people's healthy lives and radiant smiles. Without resting on the honor of five consecutive years as #1, we will continue delivering the ultimate oral care experience through the newly evolved '3rd Generation Bresmile Wash.'
