Your Smile’s Favorite Mineral

Nano-Hydroxyapatite
(nHA)

Your teeth are mostly made of hydroxyapatite — so why not brush with it? nHA is a lab-crafted version of that same enamel-mimicking mineral, engineered on a microscopic scale to bond with the surface of your teeth for a light-reflecting clean without fluoride.

Fun Fact: It was originally developed by NASA to fight bone loss in space.

Meet nanoXIM:
The Gold Standard of nHA

Not all nano-hydroxyapatite is created equal. We use nanoXIM® CarePaste by Fluidinova — the most trusted, high-performance nHA on the market. It’s synthetic, vegan, and precision-engineered for purity, safety, and serious shine.

Why nanoXIM is in a class of its own:

Certified safe for oral care by the European Scientific Committee

Rod-shaped particles mimic natural enamel crystals, unlike needle-shaped ones

Lab-engineered, not animal-derived — for consistent quality without the weird sources

Ultra-consistent for a smoother feel with every brush

No animals. No guesswork.
Just clean science.

Size Matters. Nano Wins.

Micro-hydroxyapatite is too bulky to do much more than sit on your enamel. Nano particles (under 100nm) fit into the surface’s microscopic grooves for a polished, smooth finish — with up to 25x better adhesion than their larger counterparts.

Nano sticks.

Percentages Don’t Always Tell the Full Story

Some toothpastes flaunt 10%, 15%, or more — but what they’re usually measuring is the paste, not the actual active mineral. Cocoshine delivers an effective 3% active nano-hydroxyapatite with every brush— balanced for shine, smoothness, and stability.

Too much can clump. Too little does nothing. This is the sweet spot.

81%

80.65% = base (water, glycerin, xylitol, silica)

20%

19.35% = nanoXIM CarePaste

4%

3% = active nHA

It’s not about more. It’s about just-right.

Designed By a Dentist. Loved by Smiles.

COCOLAB’s co-founder Dr. Chrystle Cu, a practicing dentist, personally vetted nanoXIM for Cocoshine. Her take? Science-backed ingredients, smooth performance, and noticeably reduced sensitivity. It even visibly whitens teeth in just one week.*

“I chose nanoXIM for its reputable science and consistent results. My sensitivity? Way down.”

FAQs

Is nano-hydroxyapatite safe?

Our formula features nanoXIM®, the only nano-hydroxyapatite certified as safe for oral care by the European Scientific Committee on Consumer Safety. It’s lab-crafted and tested for consistency. No animal byproducts, no sketch.

What makes Cocoshine different from other nHA toothpastes?

Cocoshine uses 3% of the highest-quality nano-hydroxyapatite, suspended in a silky-smooth formula designed for gentle, everyday brushing. We use rod-shaped particles (not irregular ones), sourced from nanoXIM® — the gold standard in nHA. While other brands flex high percentages or “natural” ingredients, we focus on what actually performs (and feels amazing to use). And not to brag, but Cocoshine is the best-tasting toothpaste out there, which makes brushing a ritual worth obsessing over.

Can I use Cocoshine every day?

Absolutely. Cocoshine was designed for daily use — even for those with sensitive mouths. No harsh abrasives. No peroxide. Just a clean, glow-up kind of clean you can count on, day after day.

Is it suitable for kids?

Yes! Cocoshine is non-fluoride-based and made with gentle, thoughtful ingredients — but as always, check with your dentist for age-specific recommendations. (And yes, we’ve seen kids sneak it because it tastes that good.)

Does this replace fluoride?

Nano-hydroxyapatite has been widely researched and used in Japan and Europe as a non-fluoride option that that many dentists prefer over natural toothpastes without nHA. It’s designed to interact with enamel in a way that mimics your tooth enamel. While we can’t make health claims about prevention or repair, many dentists consider nHA a science-backed option for those looking to avoid fluoride.

The Smart Choice for Modern Mouths

No fluoride. No animal byproducts. No sketch.

Just 3% of the highest-quality nano-hydroxyapatite — engineered for glowier teeth, a cleaner feel, and a brushing experience you’ll actually look forward to.
