NHAP Oral Composition Without Fluoride or Glycerin
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current oral care products, particularly toothpastes, often contain fluoride, glycerin, and surfactants, which can be harmful, especially for children, and fail to provide comprehensive oral health benefits such as anticaries, antimicrobial, antigingivitis, antiplaque, antisensitivity, anticalculus, and anti-erosion without causing tooth sensitivity.
Innovation Solution
A dental composition comprising nanohydroxyapatite (NHAP) without fluoride or glycerin, using sodium bicarbonate as an abrasive, xylitol or Stevia as sweeteners, and coconut oil as a natural oil, providing an alkaline pH and no surfactants, along with a flavoring agent like peppermint oil, to offer a range of therapeutic and aesthetic benefits.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If fluoride is used to prevent tooth decay, then caries prevention is improved, but the risk of fluorosis and toxicity increases
Solution Approach 1:
The patent removes fluoride from the oral care composition entirely, extracting the harmful element while maintaining caries prevention through alternative mechanisms (nanohydroxyapatite remineralization and alkaline pH environment) that do not carry fluorosis or toxicity risks
Solution Approach 2:
The patent changes the chemical composition parameters by replacing fluoride with nanohydroxyapatite particles and adjusting the pH to alkaline levels, thereby achieving caries prevention through remineralization rather than fluoride incorporation, eliminating the associated harmful effects
2Stability of the object's composition
If glycerin is used as a base in toothpaste, then the composition is stable and effective, but it causes tooth sensitivity and is harmful for children
Solution Approach 1:
The patent removes glycerin from the composition entirely, extracting the harmful base ingredient that causes tooth sensitivity, and replaces it with water and natural oils that provide similar functional benefits without the adverse effects on tooth sensitivity
Solution Approach 2:
The patent uses water as a temporary, harmless base that can be easily rinsed away, replacing the long-lasting but harmful glycerin base, thereby eliminating sensitivity issues while maintaining composition functionality during the brief period of application
3Productivity
If surfactants are added to oral care products, then cleaning effectiveness is improved, but the composition becomes harmful and unsuitable for children
Solution Approach 1:
The patent removes surfactants from the composition, extracting the harmful cleaning agents, and replaces them with mild natural oils and abrasives that provide cleaning effectiveness through mechanical action rather than chemical surfactant action, eliminating harm to oral health
Solution Approach 2:
The patent replaces chemical cleaning mechanisms (surfactants) with mechanical cleaning mechanisms (abrasives like sodium bicarbonate and nanohydroxyapatite particles that physically remove plaque and debris), thereby achieving cleaning effectiveness without the harmful effects of surfactants
4Reliability
If conventional toothpaste ingredients are used, then caries prevention is achieved, but comprehensive oral health benefits (antimicrobial, antigingivitis, antiplaque, anti-erosion) are not provided without causing sensitivity
Solution Approach 1:
The patent makes nanohydroxyapatite the central multi-functional ingredient that simultaneously provides caries prevention through remineralization, antimicrobial effects, antigingivitis properties, antiplaque action, and anti-erosion protection through its alkaline pH, thereby achieving comprehensive oral health benefits in a single universal ingredient without causing sensitivity
Solution Approach 2:
The patent creates a composite formulation combining nanohydroxyapatite particles with natural oils and abrasives, where each component contributes to different oral health benefits, achieving comprehensive protection (caries, microbes, gingivitis, plaque, erosion) through synergistic material combinations rather than multiple separate ingredients
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The composition effectively remineralizes teeth, reduces sensitivity, and provides comprehensive oral health benefits without the risks associated with fluoride, glycerin, or surfactants, making it safe for all ages, including children, while maintaining tooth health and aesthetics.
Implementation Method 1
Remineralization refers to the process of repair of acid damaged tooth structure—by the recrystallization of mineral salts on the tooth architecture
Implementation Method 2
remincrystallization of mineral salts on the tooth architecture
Implementation Method 3
The pH and titratable acidity of acidic beverages have been identified as the main causative agents in the initiation and progression of dental erosion

AI summary
Embodiments relate to a composition comprising nanohydroxyapatite (NHAP) in an amount about 0.5 wt. % to about 50 wt. % of the composition having a particle size in a range of about 20-100 nm, an abrasive, a sweetener, and a natural oil, wherein the composition does not contain glycerin and fluoride, wherein the composition is alkaline and a dental product, and wherein the natural oil is a plant product.
