Zimeng Multi functional Particle Size Analyzer in Toothpaste Friction AgentsParticle size detectionapplication

In the formula system of toothpaste, friction agent, as the core component accounting for 20% -60%, has a particle size similar to that of an "invisible seasoning master", directly dominating the consumer's experience and the core efficacy of the product，Common friction agents in toothpaste arepowder materialsCommonly used ones include calcium carbonatesilicon dioxideCalcium phosphate, insoluble sodium metaphosphate, calcium pyrophosphate, etc,From brushingFrom the delicate and smooth texture of teeth to the actual effect of cleaning and whitening, from tooth protection safety to product compliance, precise control of friction agent particle size runs through the entire process of toothpaste research and production.

1Particle size:The 'invisible variable' used in toothpaste

The user experience of toothpaste directly affects consumer loyalty, while the particle size of the friction agentsizeIt is the core factor that shapes this experience, and its subtle differences can bring a completely different brushing experience:

1. Small particle friction agent (<5 μ m):Delicate and smooth, suitable for sensitive needs. When the particle size of the friction agent is in the range of 200nm-5 μ m, the toothpaste paste presents a delicate feeling, and there is almost no particle sensation when brushing teeth. The oral touch is mild and comfortable. This particle size friction agent will not cause irritation to the gums, nor will it produce rough discomfort, especiallySuitable for sensitive teeth, children, and patients with periodontitisuse

2. Moderate particle size friction agent (5-20 μ m)：Balanced and comfortable, the particle size range of 5-20 μ m that meets the needs of the public is the golden choice for adult regular toothpaste and whitening toothpaste. This range of friction agents can provide moderate friction feedback, allowing consumers to feel a sense of "cleanliness in place" without causing oral discomfort due to rough particles. The paste state is uniform and stable, without excessive concern for agglomeration or layering, balancing taste and practicality

3. Large particle friction agent (>20 μ m):Friction is strong, use with caution. Friction agents with a particle size exceeding 20 μ m can cause a noticeable particle sensation. Friction feedback is strong during brushing, and some users may experience gum discomfort or foreign body sensation in the mouth. This type of friction agent is only suitable for powerful whitening toothpaste for severe cigarette and tea stains, and the addition ratio needs to be strictly controlled.

2、 Particle size control: the key lever for toothpaste efficacy

The core functions of toothpaste - cleaning, whitening, and protecting teeth - are directly related to the particle size of the friction agent, and accurate particle size detection is a prerequisite for the effectiveness to be implemented:

1. Cleaning power:Particle size adaptation is essential for efficient cleaning，Friction agents remove dental plaque, soft plaque, and exogenous pigmentation through physical friction, and the particle size directly determines the cleaning efficiency.

l Small particle size (<5 μ m) has insufficient cleaning power and is difficult to deal with stubborn stains;

l Moderate particle size (5-20 μ m) can achieve a balance between efficient cleaning and gentle tooth care;

l Excessive particle size (>20 μ m) may have strong cleaning power, but it can easily damage dental enamel.

Zimeng ZML320 adopts a high-definition imaging system and intelligent analysis software, which can accurately characterize the morphology and size of friction agent particles through multi-dimensional parameters, helping enterprises optimize formulas, ensure cleanliness meets standards, and do not damage teeth.

2. Dental safety:The compliance particle size is the bottom line to ensure that the Mohs hardness of enamel is 5-6. Excessive friction agent particles can scratch enamel, and long-term use can easily lead to issues such as dentin sensitivity and dental caries. The particle size of toothpaste friction agent should be controlled within a reasonable range, and the friction value should meet the requirements of GB/T 35832 (≤ 250).

Zimeng ZML320 has been calibrated with NIST traceable standard particles, with an accuracy error of less than 3%. It can accurately detect whether the particle size of the friction agent meets the national standard requirements, providing data support for product safety and avoiding compliance risks caused by particle size exceeding the standard.

IIIZML320Accurate detection of toothpaste quality

The optimization and control of friction agent particle size cannot be achieved without the support of professional testing equipment. Zimeng Technology ZML320 Multi functional Particle Size AnalyzerThe advantage lies in:

1. Adapt to diverse scenarios:The detection range covers 200nm-3000 μ m, which can meet the particle size detection needs of different types of friction agents (hydrated silica, calcium carbonate, calcium hydrogen phosphate, etc.). Whether it is solid powder friction agent raw materials or dispersed particles in paste, it can be accurately analyzed.

2. Assist in formula optimization:Through functions such as automatic particle recognition, video tracing, and data backup, the true state of friction agent particles can be captured in real time, helping researchers optimize multi particle size compounding schemes and balance cleaning power, taste, and safety;

From consumers' brushing experience to the market competitiveness of products, precise control of friction agent particle size is crucial for toothpaste companiesimportantOne of the competitive advantages. Zimeng Technology is deeply involved in the field of particle size analysis, providing accurate and compliant solutions for the particle size detection of toothpaste friction agents,moreProvide technical support for the research and quality control upgrade of toothpaste and pharmaceutical health industries, and promote high-quality development of the industry.
