We support 'April Dream,' which aims to make April 1st a day to share dreams. This press release is the dream of 'Dr.Oral.'
Dr.Oral, an oral care brand developed by Eclore Co., Ltd. (Headquarters: Yodogawa-ku, Osaka; President: Chisato Mitani), is providing new value to daily oral care by utilizing innovative materials born from eggshells, an unused resource.
By adding the concept of 'polishing your smile' to tooth brushing, we aim to support confidence and positive communication, realizing a society where everyone can be confident in their own smile.
'To the best smile in your life.'
[Challenge of 'Polishing Your Smile' Started with Eggshell Apatite]
The origin of Dr.Oral dates back to 2016. Focusing on the 'mouth,' which influences the impression of a smile, we encountered 'Eggshell Apatite*1' while searching for materials to bring innovation to oral care.
In Japan, approximately 260,000 tons of eggshells are discarded annually, and most are incinerated, contributing to CO2 emissions.
On the other hand, eggshells are highly functional materials with a sophisticated and delicate structure that has minute air pores to protect the inside from the outside. Apatite is a component that makes up teeth and bones, accounting for 97% of tooth enamel and 63% of dentin, holding great potential for application in oral care.
Focusing on this 'discarded value' and 'human-friendly component,' we took on the challenge of applying it to oral care products. As a result, in 2017, we launched the world's first tooth powder containing eggshell apatite*1, and Dr.Oral was born.
*1: Hydroxyapatite (cleaning agent)
[Evolving Technology: Toward 'Bio 3D Apatite®*1']
2025, seven years after the brand's birth. In pursuit of even greater effectiveness, eggshell apatite*1 has evolved. This is 'Bio 3D Apatite®*1,' which combines three different particle sizes.
Dr.Oral's desire to 'deliver highly specialized oral care' and the technical capabilities of Bio Apatite Co., Ltd., a pioneer in eggshell apatite, have fused to create the world's only oral care ingredient.
It is an ingredient that pursues higher whitening effects than ever before through a multi-faceted approach, including the adsorption of yellowing and odors, plaque removal, and smoothing the irregularities of the tooth surface*2.
Because it is something you put in your mouth, we are committed to a formulation design mainly based on naturally derived ingredients, thoroughly considering safety and security.
The popular No. 1 3D Whitening Powder has a natural origin index of 99%*3 and is MADE IN JAPAN.
