Preservative-Free Children Toothpaste Composition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing toothpastes for children contain preservatives, which may not be safe due to their weak immune system and sensitive oral mucosa, and the risk of swallowing toothpaste, necessitating a preservative-free alternative that effectively cares for their tender enamel and gums.
Innovation Solution
A preservative-free toothpaste composition comprising vitamin E, vitamin C, calcium glycerophosphate, xylitol, sorbitol, polyethylene glycol, cellulose, hydroxypropyl guar gum, sodium lauryl sulfate, and flavors, with specific weight percentages, providing nourishment and protection to children's teeth and gums without preservatives.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of stationary object
If preservatives are added to toothpaste to prevent decomposition and microbial growth, then the shelf life and stability of toothpaste are improved, but the safety of toothpaste for children deteriorates due to potential harmful effects on their sensitive oral mucosa and weak immune system
Solution Approach 1:
The patent removes preservatives from the toothpaste formulation entirely, extracting the harmful component while maintaining product stability through alternative means (food-grade ingredients and proper packaging)
Solution Approach 2:
The patent changes the chemical composition parameters by using food-grade ingredients with natural preservative properties and controlling the pH and water activity levels to prevent microbial growth without adding synthetic preservatives
2Object-affected harmful factors
If the toothpaste formulation uses food-grade materials without preservatives to enhance safety, then the safety for children is improved, but the stability and resistance to decomposition deteriorates
Solution Approach 1:
The patent uses a composite formulation of multiple food-grade ingredients (xylitol, sorbitol, glycerin, natural flavors) that work together to maintain stability and prevent decomposition through their combined natural preservative properties
Solution Approach 2:
The patent introduces aluminum foil packaging as an intermediary barrier that protects the preservative-free formulation from external factors causing decomposition, while the food-grade ingredients serve as intermediaries with natural antimicrobial properties
3Reliability
If preservatives are used to continuously inhibit microbial growth in insufficiently sterilized toothpaste, then the prevention of decomposition is improved, but the harmful effects on children's sensitive oral mucosa worsen
Solution Approach 1:
The patent converts potentially harmful trace contaminants from insufficient sterilization into beneficial effects by using food-grade ingredients with natural antimicrobial properties that safely eliminate microbes without harming oral mucosa

AI summary
The present invention discloses preservative-free toothpaste for children. The composition forming the preservative-free toothpaste for children consists of vitamin, calcium glycerophosphate, xylitol, sorbitol, polyethylene glycol, cellulose, hydroxypropyl guar gum, sodium lauryl sulfate, flavors and deionized water. The composition contains, by weight percentage, 0.01-0.06% of vitamin, 0.1-0.5% calcium glycerophosphate and 0.1-1% of xylitol. The vitamin comprises both vitamin E and vitamin C. In the present invention, vitamin E, vitamin C, calcium glycerophosphate and xylitol are combined in a certain proportion. The vitamin nourishes the children's tender gums. The calcium glycerophosphate provides calcium supplementation to the teeth. The xylitol has a reduced content of sugar, which prevents tooth decay and strengthens the teeth.
