Oral Care Compositions and Method for Preparing the Same A More Stable Toothpaste Recipe

This patent describes an oral care composition, such as a toothpaste or gel, along with a method for making it. It comes from the Colgate-Palmolive Company, one of the world’s largest makers of toothpaste and personal care products.

The Problem

A toothpaste is a surprisingly complex mixture. It has to carry an active ingredient such as a fluoride that protects teeth, hold gritty polishing particles in a smooth paste, taste and feel pleasant, and stay stable on the shelf for a long time. Those goals often pull against each other: some actives lose potency when they interact with other ingredients, thickeners can make a paste too stiff or too runny, and the order in which components are combined can change the final texture and stability. Formulators need recipes and preparation methods that keep the active effective, give a consistent feel, and remain stable over the product’s life.

What This Invention Does

The patent describes a family of oral care compositions built from a defined set of ingredients, together with a method of preparing them. The composition combines an active with thickening and binding agents, humectants that keep the paste moist, and other functional components chosen and proportioned to give the desired stability and feel. Equally important is the preparation method: the patent specifies how the components are brought together and processed so the finished product has the intended consistency and the active stays effective. The IPC classifications point to formulations involving polymers and other agents used to control texture and delivery. By claiming both the composition and the way it is made, the filing protects the recipe and the process that reliably produces it.

Key Features

• Defined composition. The product combines an active with thickeners, binders, humectants, and other functional agents in set proportions.
• Preparation method. The patent specifies how the ingredients are combined and processed to reach the target result.
• Consistent texture. The formulation and method are aimed at a stable, pleasant paste or gel consistency.
• Stable active. Ingredient choices help keep the active ingredient effective over the product’s shelf life.
• Recipe and process protected. Claims cover both the composition and the method of making it.

Who Is Behind It

The applicant is the Colgate-Palmolive Company, a New York-based consumer products company whose Colgate brand is one of the most widely sold toothpastes in the world. The named inventors are Suman Chopra, Guisheng Pan, and Gregory Szewczyk. This filing is a divisional application from an earlier related Australian application.

Why It Matters

Oral care is a huge everyday category, and the difference between products often comes down to formulation: how stable the active is, how the paste feels, and how consistently it can be manufactured at scale. A recipe and preparation method that improve stability and texture give a real edge in a market measured in billions of tubes. Protecting the formulation in Australia supports the company’s oral care range in the local market.
