[Pearl Science] A Scientific Look at Nano Pearl Powder

Nanomaterials refer to materials that have at least one dimension in the three-dimensional space at the nanometer size (0.1-100 nanometers) or are composed of them as basic units.

Nanomaterials can be roughly divided into four categories: nanopowders, nanofibers, nanofilms, and nanoblocks.

(Note: 1 meter = 1000 millimeters, 1 millimeter = 1000 micrometers, 1 micrometer = 1000 nanometers)

Nanopowder among nanomaterials, also known as ultrafine powder or ultrafine powder, generally refers to powder or particles with a particle size of less than 100 nanometers. It is a solid particulate material in an intermediate state between atoms, molecules and macroscopic objects.

If the size of the pearl powder particles produced by a certain process is between "1-100 nanometers", we can also promote these pearl powders as "nano (grade) pearl powder". In fact, it is a question of internal standard grading in an enterprise. Based on the definition of nano powder, even if they are all promoted as "nano pearl powder", the particle sizes of pearl powders from different brands or even different batches of the same brand are not exactly the same.

Generally speaking, the finer the pearl powder particles, the easier it is to digest. The advantage of nano pearl powder is that the particles are much finer than ordinary pearl powder.

For merchants, as long as the product is genuine, the actual size of the pearl powder particles can reach the nanometer level, there are legal and compliant implementation standards (national standards, local standards or corporate standards that are publicly filed), and the actual product is consistent with the claims on the advertising packaging, nano pearl powder can still be a good selling point; and as long as the publicity is not exaggerated, there is no policy risk in terms of government supervision.

For consumers, as long as the product is genuine, safe, hygienic and effective, nano pearl powder is also a good choice. However, the production process of nano pearl powder is more advanced, the cost will be higher than that of ordinary pearl powder, and the corresponding price will also be higher.

Nano pearl powder was initially a concept that was hyped up by merchants taking advantage of the popularity and traffic of the high-tech concept of "nano". Now that more and more people understand it, consumers are becoming more rational, and market supervision is becoming more standardized, merchants no longer use this concept for marketing, but instead use "ultrafine pearl powder". The current national standard for pearl powder does not even have the definition of "nano pearl powder".
