Product Advantages & Usage Instructions Core Advantages •Precisely controlled low RDA value, verified by standard abrasion testing methods •Industry-leading purity standards, suitable for pediatric and sensitive oral care •Rounded particle morphology for maximum gentleness without sacrificing cleaning efficacy •Complete safety documentation supporting regulatory submission for children's products •Customizable particle size and abrasion level for different age groups and sensitivity levels Usage Instructions 1.Recommended addition ratio is 12% – 18% in children's and sensitive toothpaste formulas. 2.Can be blended with small amounts of standard abrasive silica to adjust cleaning power while maintaining low abrasion. 3.Ensure thorough dispersion during mixing to avoid particle agglomerates which may cause gritty mouthfeel. 4.For children's toothpaste, validate total formulation safety according to local pediatric cosmetic regulations. 5.Store in sealed, dry conditions to maintain particle structure and performance. Application Scenarios Children's Toothpaste (Ages 3-12) Specially designed for primary and mixed dentition stages, providing gentle cleaning with maximum safety for developing teeth. Anti-Sensitivity Toothpaste Suitable for dentin hypersensitivity products, delivering daily cleaning without aggravating sensitivity symptoms. Post-Dental Treatment Care Ideal for post-scaling, post-whitening and post-restoration oral care products where enamel may be temporarily more susceptible to wear. Gentle Oral Care for Elderly Consumers Suitable for oral care products targeting seniors with receding gums and exposed dentin requiring mild cleaning.
