What feature of long-chain monomers tends to reduce negative effects like odor and irritation?

Long-chain monomers are characterized by their molecular structure, which includes a more extended chain of repeating units. This longer chain structure often leads to a variety of beneficial properties, particularly when it comes to formulations used in cosmetic applications like eyelash extensions.

One reason the longer chain structure is advantageous is that it helps to evenly distribute the chemical components within the product. This can minimize the concentration of any irritating agents or scents that could be released during the application process. As a result, formulations with long-chain monomers can often reduce the likelihood of odor and irritation, making them more user-friendly and suitable for a wider range of clients.

Additionally, long-chain monomers tend to exhibit better stability and lower volatility compared to their shorter counterparts. This means that they are less likely to evaporate quickly or break down into potent, irritative byproducts, again contributing to a more pleasant experience for both the practitioner and the client.

In essence, the structural properties of long-chain monomers play a key role in enhancing the overall formulation quality, leading to a reduction in negative effects like odor and irritation, which is highly desirable in the context of products applied close to sensitive areas such as the eyes.
