How to test the quality of toothpaste

Question 1: How to distinguish good from bad Toothpaste? Look at the appearance of the paste: the paste is more delicate and smooth, usually high-grade silicon as an abrasive, you can use it with confidence; 2. Taste the taste of brushing teeth: If you feel rough, there are sand-like particles stuck in your mouth, you need to gargle many times, mostly toothpaste containing rough abrasives, it is recommended to stop immediately; 3. Brush: Brush different toothpaste paste 6 to 10 times on the surface of the CD box like brushing your teeth, and identify the difference by comparing the brush marks. Secondly, toothpaste should be selected according to its anti-moth efficacy, that is, to choose fluoride toothpaste. With 76% of 5-year-olds in China still suffering from tooth decay, there is still a long way to go to promote the use of fluoride toothpaste. It is suggested that the majority of consumers should pay special attention to choosing high-quality toothpaste containing fluoride to prevent cavities and ensure that the teeth do not wear

Question 4: How to identify the quality of toothpaste? Toothpaste is a daily consumer product that people must use every day, and its quality is directly related to human health and safety, so pay attention to identification when purchasing. Look at the thin consistency: if the extrusion is laborious or particularly thin and wet, it is not round, indicating that the quality has changed. Look at the color: should be white, chlorophyll toothpaste should be light green. If black appears, it may be that the tin layer on the inner wall of the lead hose is uneven or too thin, and the paste contacts the lead layer during extrusion. Blackened toothpaste contains lead, which is harmful to the human body and will be chronic poisoning if used for a long time. See if there are hard particles: Apply a little toothpaste on the glass, press it with your finger, see if there are hard particles, if there will be scratches when brushing teeth. See whether there is water seepage phenomenon: squeeze some toothpaste on the raw paper, spread out evenly with your fingers, see whether the surface of the paper has water seepage, good quality toothpaste is very little water seepage. Guard body: the hose should be straight, without wrinkles, and the teeth of the tube tail should be neat, without holes or cracks. Look at the shelf life: the "life" of toothpaste is 10 months, try to buy products produced recently, expired products have an impact on quality, do not buy. In addition, the amount of foam does not determine the effect of cleaning teeth.

Question 5: How to distinguish the grade of toothpaste is good and bad? There is a popular belief on the Internet that the color bars at the bottom of the toothpaste tube represent different ingredients, and green means natural; Blue indicates some natural and some medicinal ingredients; Red means half natural and half chemical; Black means it's all chemical.

The color bar at the bottom of the toothpaste packaging is used to locate and identify products during the toothpaste production process, according to a note posted on the website of the China Oral Cleaning and Care Products Industry Association. The electric eye positioning function is very common in the printing of hose packaging, which is used to apply the positioning sense of the tail sealing machine when the hose is automatically filled after the product is made. After the filling is completed, the hose is placed on the automatic sealing machine, the machine senses the relevant color points, and starts to automatically seal the hose to ensure that the packaging is in the correct position when the tail is sealed, and has nothing to do with the composition of the product. The point of view mentioned in the rumor that "toothpaste ingredients are differentiated by the color bar at the bottom of the toothpaste tube" is wrong and has no guiding significance for consumers.

Main use: tracking and cutting pipe in the process of making pipe

Toothpaste is produced into a roll of materials, the whole roll of materials need to be processed into a single product of the hose, now the latest processing equipment is fully automatic cutting, in the cutting process, the machine equipment is relying on the automatic tracking of the electric eye, every track to a cursor, automatically cut it, the existing equipment per minute cut pipe 120~200, if there is no this cursor, The machine will cut randomly, causing problems of varying lengths (this cursor will be cut off after the toothpaste body seal is installed, and some will be left with a part).

Professional name: hose tail cutting cursor

Main use: Ensure that the printing plate is centered when sealing the end

After the toothpaste is made into a hose, the toothpaste is poured into the assembly line, and the final packaging procedure is entered. At this time, the tube is round, and if there is no positioning, the hose tail seal will have no standard, resulting in layout confusion. After printing the cursor on the layout, when the electric eye on the assembly line detects the cursor, it will rotate and position, and then the next step will complete automatic packaging. Ensure that the position of the whole batch package is consistent.

Different toothpastes actually have different effects:

· Anti-tartar toothpaste? These toothpastes claim to prevent plaque calcification, thereby reducing the rate of calculus formation. The main ingredients are pyrophosphate or zinc citrate.

· Anti-plaque toothpaste? This kind of toothpaste can inhibit the accumulation of dental plaque, weaken the toxin produced by bacteria on the periodontal tissue, and reduce the chance of causing periodontal disease. Anti-plaque toothpastes on the market contain different main anti-plaque ingredients, such as zinc citrate.

· Whitening Toothpaste? This kind of toothpaste contains relatively coarse particles, which work to remove stains from the surface of the teeth, so as to get the effect of bleaching teeth. However, long-term use of these toothpastes will make the surface of the teeth rough, and eventually make tooth stains more likely to deposit on the teeth.

Children must use children's fluoride toothpaste, because the fluoride content is relatively low, so that they can avoid swallowing excessive fluoride.

Question six: How to do the experiment to know whether the toothpaste is good or bad seems to only need to look at the end of the plaster there is a rectangular point in the middle, look at the color, black is not good

Question 7: How to distinguish the quality of toothpaste is good or bad toothpaste regardless of quality, cheap and expensive effect is the same

Question eight: How to distinguish the quality of toothpaste?

1) Look at the thin consistency: if the extrusion is laborious or particularly thin and wet, it is not round, indicating that the quality has changed.

2) Look at the color: should be white, chlorophyll toothpaste should be light green. If black appears, it may be that the tin layer on the inner wall of the lead hose is uneven or too thin, and the paste contacts the lead layer during extrusion. Blackened toothpaste contains lead, which is harmful to the human body and will be chronic poisoning if used for a long time.

3) To see if there are hard particles: apply a little toothpaste on the glass, use your finger to hold it down, see if there are hard particles, if there will be scratches when brushing teeth.

4) See if there is water seepage: squeeze some toothpaste on the raw paper, spread it evenly with your fingers, and see if there is water seepage on the back of the paper. Good quality toothpaste rarely seeps.

5) Watch body: the hose should be straight, without wrinkles, and the teeth of the tube tail welding should be neat, without holes or cracks.

In addition, the amount of foam does not determine the effect of cleaning teeth.

To choose toothpaste, the first thing to know is that toothpaste is not a magic weapon for healthy teeth, it is just an aid for brushing teeth, with friction and removal of plaque, cleaning and polishing the tooth surface, and refreshing the mouth. At present, the toothpaste used in China is divided into ordinary toothpaste, fluoride toothpaste and drug toothpaste three categories.

The main ingredient of toothpaste is abrasive (calcium carbonate), in addition, add some spices personal feel, abrasive to fine and uniform only good, if the paste body is not uniform, it is not a good toothpaste. In addition, if there is no shortage of fluoride in the drinking water in your area, try not to use fluoride toothpaste.

Hope to help you! Please comment, thank you

Question nine: How to distinguish between good and bad toothpaste to see whether there is water seepage phenomenon: squeeze some toothpaste on the raw paper, spread it evenly with your fingers, and see whether there is water seepage on the reverse side of the paper.

Guard body: the hose should be straight, without wrinkles, and the teeth of the tube tail should be neat, without holes or cracks. Look at the shelf life: the "life" of toothpaste is 10 months, try to buy products produced recently, expired products have an impact on quality, do not buy. In addition, the amount of foam does not determine the effect of cleaning teeth.

Question 10: How can toothpaste be divided into good and bad? Look at a small rectangle on the tail of the toothpaste. If it is green or blue, it is natural or semi-natural. Black is artificial
