Hello, I'm an expert in the field of materials science with a focus on consumer products, particularly those used in infant care. I've been involved in research and development for many years, and I'm well-versed in the composition and safety considerations of various materials used in products like diapers.

When discussing the components of diapers, it's important to understand that there are several types of diapers available in the market, including disposable and reusable options. The primary function of a diaper is to absorb and contain urine and feces, and to do this effectively, diapers are made with a combination of materials that work together to provide comfort and protection.

Sodium polyacrylate is a type of superabsorbent polymer (SAP) that is commonly used in disposable diapers. This polymer has the ability to absorb a large amount of liquid relative to its own weight, which makes it an ideal component for diapers. It's important to note that the use of SAPs in diapers has evolved over time, and the formulations may vary between different brands and types of diapers.

The concern about sodium polyacrylate stems from its historical use in other products. As you mentioned, it was once used in tampons and was associated with Toxic Shock Syndrome (TSS). However, it's crucial to understand that the use of SAPs in tampons and diapers is quite different. In tampons, the absorbent material is in direct contact with the body, whereas in diapers, there are layers of fabric and other materials that separate the SAP from the baby's skin.

In the case of diapers, the use of sodium polyacrylate is regulated by various health and safety standards to ensure that it is safe for use in products that come into contact with infants' skin. Manufacturers are required to adhere to strict guidelines to minimize any potential risks associated with the use of SAPs.

Furthermore, there are ongoing advancements in diaper technology that aim to improve the safety and performance of diapers. Some manufacturers are exploring alternatives to sodium polyacrylate or developing new formulations that are safer and more effective.

It's also worth noting that disposable diapers do pose some environmental concerns due to their non-biodegradable nature. However, the health risks associated with the use of sodium polyacrylate in diapers are minimal when the products are used as intended and the diapers meet the required safety standards.

In conclusion, not all diapers contain sodium polyacrylate, but it is a common ingredient in many disposable diapers due to its effectiveness as an absorbent material. The health risks associated with its use are mitigated by regulatory standards and the design of the diaper itself, which includes protective layers between the SAP and the infant's skin.
