Every heard of it?
Nanoparticles are in personal care products. Most nanoparticles serve as delivery agents that help other ingredients penetrate into the skin and homogenize the distribution of colored pigments in cosmetics, making the delivery of sunscreen and other treatments less greasy. They also create a silky texture found in creams and powders. Nanoparticles are smaller than a human cell, so tiny that they are invisible to the human eye.
Why it’s not welcome
This is a new ingredient technology and there are a lot of unknowns in terms of nanomaterials and their effect on human health and our planet. What we do know is that when inhaled, nanoparticles can become embedded into your lungs. Another potential issue is that they are so small they could potentially be absorbed into the bloodstream. We just don’t have enough information on this, and the little we do have suggests that it is not good. So until we know more, that’s not a health risk we are willing to take, especially when it comes to our customer’s health (1). Plus the chemicals these nanoparticles are delivering are typical of a toxic composition.
Although there is little definitive evidence, the health effects of nanoparticles are likely to depend also on their shape. A significant example is nanotubes, which may be only of a few nanometres in diameter but a potential length of several micrometres. A recent study showed a high toxicity of carbon nanotubes which seemed to produce harmful effects by an entirely new mechanism, different from the normal model of toxic dust (2).
Before you panic
The research is contentious and not yet conclusive. But we know that there are safer alternatives, so why risk it? At Soap Hope, we think it’s far more important to stay ahead of the curve when it comes to ingredient safety, so when in doubt we ban it for the safety of our customers, their families, and their homes.
We’re in good company
Every Maker (the brands we carry on our shelves) has either never used Nanoparticles or eliminated it from their formulas in favor of safer alternatives that are allowed at Soap Hope. The ingredients in each and every product at Soap Hope are vetted for safety before we decide to carry them. We care as much as you do about what we put in and on our bodies.
