A published record of the oral care chemistry behind Quia Group.

Great oral care products are built on real chemistry — and real chemistry leaves a paper trail. Quia Group President and formulator Matt Spaid is a named inventor on multiple United States oral care patent applications, covering tooth-whitening systems, effervescent two-part formulations, slow-release oral hydrogels, and novel ways to deliver active ingredients through the mouth. Below is a look at that published work: the official summary from each application, alongside a plain-English explanation of what it actually does.

ORAL DELIVERY SYSTEM

Hydrogel Sheets and Shapes for Oral Care

U.S. Patent Application (Published)

SUMMARY

A hydrogel for use in oral care. The hydrogel is ion beam cross-linked, the hydrogel is adapted to be disposed in the oral cavity and may be adapted to provide a denture fixative or may be loaded with a whitening agent for use in whitening one or more teeth and disposed on or adjacent one or more teeth and the whitening agent is slow-released to whiten the one or more teeth. Other loading materials may include materials for treatment of alveolitis or malodor, inter alia. The present invention is a new hydrophilic oral and dental cohesive hydrogel sheet designed to securely grip and cushion prosthetic devices in the human mouth with the further ability to slow release antimicrobial or other orally desirable agents.

SIMPLIFIED EXPLANATION

This invention is a soft, water-loving gel sheet that you place inside your mouth. Because it grips gently and holds its shape, it can work as a comfortable denture cushion and adhesive — but its real cleverness is that it can be loaded with an active ingredient and release it slowly over time. Load it with a whitening agent and it whitens teeth gradually; load it with an antimicrobial and it can help fight malodor or soothe irritated tissue. Think of it as a time-release patch, designed specifically for the mouth.

NUTRITIONAL DELIVERY

Corporeal Delivery of Carotenoids

Status
U.S. Patent Application (Published)

SUMMARY

A method for delivery of a phytochemical supplement to a corporeal body. The method of delivery comprises providing a phytochemical supplement in an orally acceptable composition and applying the orally acceptable composition including the phytochemical supplement in contact with a feature of the oral cavity of a corporeal body. An oral care composition comprising a phytochemical supplement for one or more of ingestion or trans-mucosal absorption and a method for making the same are also disclosed.

SIMPLIFIED EXPLANATION

This invention turns everyday oral care into a way to deliver beneficial plant nutrients. Carotenoids are the antioxidant compounds that give carrots and tomatoes their color, and this method builds them into an oral-care product so the body can absorb them — either by swallowing, or directly through the tissues that line the mouth. In short, it's a delivery system that lets a toothpaste, gel, or rinse double as a nutritional supplement.

EFFERVESCENT FORMULATION

Foaming Compositions and Methods

Inventors
Martin Giniger, Matt Spaid
Publication No.

Filed
Published
Status
U.S. Patent Application (Published)

SUMMARY

An effervescent foamable two-component oral care composition in which a first component contains an acid, and a second component contains an alkaline source such as a carbonate; wherein one or both of the first and second components also contains a surfactant; and, wherein the first and second components are combinable to form an effervescing oral care foam.

SIMPLIFIED EXPLANATION

This is oral care that fizzes to work. The product comes in two parts — one acidic, one alkaline (like a carbonate) — with a foaming agent built in. When the two parts combine, they react and effervesce, much like an antacid tablet dropped into water, except the fizzing happens right in your mouth. That active foam carries the cleaning power into all the places a static paste can miss. It's the satisfying fizz of baking soda chemistry, engineered to actually clean.

WHITENING

Foaming Oral Care Compositions of Baking Soda and Vinegar

Inventors
Martin Giniger, Matt Spaid, Brian Olson

Published
Status
U.S. Patent Application (Published)

SUMMARY

A foaming oral care composition of two parts; namely, a vinegar part, and a baking soda part. Also included are alternative additional components such as lemon oil, orange oil, xanthan gum or an oxidizing whitener such as hydrogen peroxide or sodium chlorite. Methods for making and using such an oral care composition are included as well.

SIMPLIFIED EXPLANATION

This invention takes the classic baking-soda-and-vinegar reaction and puts it to work on your teeth. The acidic part (vinegar) and the alkaline part (baking soda) are kept separate until the moment of use, then combined to create an active, cleaning foam right in the mouth. The formula can be dialed up with flavor oils like lemon or orange, thickeners for the right texture, or an oxidizing whitening agent such as hydrogen peroxide — making it a foaming clean-and-whiten system built on simple, familiar chemistry.
