Natural Children's Toothpaste ‘Jack N' Jill’ Gains Popularity as a Back-to-School Essential!

Australian organic children's toothpaste brand Jack N' Jill attracts significant attention from parents for combining safety with cavity prevention effectiveness.
‘Jack N' Jill,’ the Australian natural children's toothpaste brand that officially launched in Korea this past February, is gaining popularity as a "must-have" item for daycare enrollment in the new March semester. As daycare centers are places where children often learn to brush their teeth independently away from their parents for the first time, young mothers are focusing their attention on natural toothpastes that offer both cavity prevention and guaranteed ingredient safety.
Responsible for the oral health of children worldwide for 76 years since 1949, Jack N' Jill has swept the No. 1 sales spot in the premium natural children's toothpaste category at major retailers, including the world's largest organic specialty market ‘Whole Foods Market,’ Europe's largest natural health food chain ‘Holland & Barrett,’ the US organic market ‘Erewhon,’ and the world's largest e-commerce platform ‘Amazon.’
Jack N' Jill is made with natural ingredients safe even for young children who frequently swallow toothpaste and contains a high content of 40% Xylitol to aid in cavity prevention. Notably, it is the only children's toothpaste to have acquired the ‘ECOCERT’ certification—known for its rigorous standards in France—for its finished product.

[Interview] Jack N' Jill CEOs, the Bernhauts: “Let’s Brush Happily with Toothpaste That’s Safe to Swallow”

‘Jack N’ Jill,’ Australia's No. 1 Organic Children's Toothpaste Brand Created by a Married Couple Jack N’ Jill, the brand leading the global premium children's toothpaste market, is landing in Korea. What is the secret behind this children's toothpaste that has captured the hearts of safety-conscious parents? We met with CEOs Justin and Rachel Bernhaut, who visited Korea.

Every parent feels the same about wanting to give only the best to their child. Justin and Rachel Bernhaut, the CEO couple behind Australia's No. 1 organic children's toothpaste brand 'Jack N' Jill,' started with that same mindset. It was their sense of lack and frustration with existing products that ultimately led to the creation of the current Jack N' Jill toothpaste.
It began over 10 years ago when the couple was living in New York as newlyweds. Rachel, filled with joy upon her first pregnancy, started preparing baby products one by one and became interested in safe items for children.
"We were living in New York at the time. As soon as I found out I was pregnant, I started preparing baby items one by one. Back then, products using chemicals were commonplace, but I felt uneasy since it was for my young child. As I looked around with interest, I realized there were quite a few consumers, including myself, interested in organic and natural-origin products. I connected with them and tried to find products with the safest possible ingredients for my child."
