About this Company

Welcome to Frontier Pharmaceutical. We are a family-owned business that was founded in 1993 by Howard Alliger. Howard pioneered the utilization of chlorine dioxide for personal care uses. He developed DioxiCare, a proprietary way of making chlorine dioxide, found in all our products. 28 years later, we are the leading US manufacturer of chlorine dioxide products.

Since Howard’s passing in 2020, our company is now led by Valerie, Howards’ daughter. Val worked alongside her dad for 26 years and continues his legacy of increasing the awareness of chlorine dioxide and how it can help people and animals treat a number of different ailments.

Using our DioxiCare technology, we currently manufacture products for oral care, skin care and wound care. The oral care products are recommended and used by dentists, oral surgeons, oral hygienists, and dental schools, in addition to the general public.

Here at Frontier, we pride ourselves with the quality of all our products and the results they achieve for our customers. All products come with an iron-clad money back guarantee.

Customer Service is also very important to us. Our friendly, helpful staff are ready to help you during our regular business hours, 9:00 am to 5pm EST. We answer our phones and welcome talking with you should you have any questions.

I love this product as it helped clear my sinuses and reduce inflammation. It's better and more effective than saline spray!

Order was shipped and received promptly. I loved the products and appreciated the spare tops when toothpaste is low and able to get the rest out. Also I received some samples on the antiseptic spray that healed a bad crusty scab that I've had for years! Amazing!

I love this product and how clean my teeth feel! It's as fresh as when you leave the dentist after a fluoride treatment. Also, it whitened my teeth so continue to use regularly!

I love this product and how fresh my mouth feels! I have used this product when I had mouth ulcers and healed it within a couple days. Also, it helps with sore throats and much faster and better than salt water. It cleans toothbrushes and retainers too! Very effective and fast!

Excellent company. Just wish the toothpaste bottles didn't get clogged all the time. They need to design the paste to not clog so much.

Nail-It ClO2

Effective, effective effective in a very difficult to treat subungual fungal infection. No irritation, pain or redness, just EFFECTIVE treatment of toenail fungal infection! No need to soak your toe for hours, no need to take expensive meds by mouth that can harm your liver, no need for repeated testing of liver function studies to be sure your liver is not adversely affected by the treatment. The product is no doubt the very best option for toenail fungal infections. I recommend 100%.

Expensive for how little it is- but so are cavity fillings and root canals and all the dentist appointments! Works very well to clean your teeth and remove any biofilm buildup.

DioxiCare Pet Earigant SP Otic Cleanser: Outstanding

Outstanding product for resolving an ongoing, and difficult-to-clear Ear issue with Pets ears. After 1 week of using this product the problem was gone. Now we just occasionally apply a few drops to be sure it doesn’t return. It’s an amazing product and we are forever grateful customers of the DioxiCare line overall. Thank you

LIfe time user of Colgate....WON'T GO BACK!

I'm the type of consumer that tends to just stick to what I know. With toothpaste, I always used Colgate before. Couldn't even stand Crest as it would cause sensitivity issues for me. So, when my sister recommended I try DioxiBrite, there was very little chance I would make it through the first few days. Well, HOLY BUCKETS!! From the first use, I knew I liked how it cleaned my teeth. I've gone through two complete sets and am now making another big order for more. I've stopped using Colgate all together. Even took Dioxibrite on vacation because I didn't want to be without it. Teeth feel cleaner, look whiter, feel smoother. Gums feel healthier. Also noticing fewer incidents of canker sores.

If you’ve ever suffered with a sore tooth or sore gum, this is likely to be your best friend. The toothpaste does not remove tooth enamel, unlike just about every other toothpaste I’ve tried. Instead it is able to get into small tight spaces between teeth and work its magic. Tastes pretty good, too. The mouthwash is pleasant tasting and really lasts, from bedtime to morning. These are great products that are worth every penny. I’ve noticed far less trouble with occasionally sore teeth or gums, too. It performs as advertised.

Thanks for making these wonderful products available for purchase. I need also the liquid CDS, which I gather is the abbreviation for chlorine dioxide solution, easier than CD for seniors to tolerate. Wish you had that, too.

Why Trust Verified Reviews?

Verified Reviews are real, authentic reviews collected from actual paying customers, using Shopper Approved's Verified Review Platform. When reviews are Verified by Shopper Approved, you know that you can trust them to make better buying decisions.

Unverified Reviews on the other hand, are reviews collected by Open Review platforms that allow anyone to leave a review, without any validation or proof of purchase. Unfortunately, most reviews you read online are Unverified Reviews, and can't be trusted.

As a consumer, here's how you can tell the difference:

Verified Reviews from Verified Review Platforms like Shopper Approved, have much higher review counts and higher overall Star ratings, because they attempt to collect reviews from every single paying customer.

Unverified Reviews from Open Review Platforms, tend to have much lower review counts and more negative Star ratings, because people with bad experiences are primarily those who leave reviews. This often creates a misleading, inaccurate portrayal of a companies true reputation.

So, when searching for Verified Reviews, look for the name you know you can trust. Shopper Approved.
