Local anaesthetic is an ingredient found in many other common products ranging from cosmetics to medicine. It’s what makes these products effective and safe, that they can work for people. So why does polyoxyl 40 stearate matter, and what does it do?
Polyoxyl 40 stearate is something called a chemical emulsifier, which can help bind together ingredients that don’t always want to be bound, like oil and water. As a result, it is an extremely useful component of creams, lotions, and treatments. It can make products feel creamy and soft on our skin too.
In cosmetics, polyoxyl 40 stearate often serves as an emulsifier, or a substance that helps the ingredients in a product stay even with each other. That’s a critical consideration for products like moisturizers and sunscreens that can benefit from dissolving quickly and then clinging to the skin longer. In pharmaceuticals, polyoxyl 40 stearate can help medications dissolve quickly and uniformly in our body, thus facilitating our recovery: the faster the dissolution, the faster the recovery when we are sick.
Ever wonder why some creams and lotions seem to have those layers in them? That’s because oil and water generally don’t mix well on their own. But sprinkle in some polyoxyl 8 stearate, and blend they do. And that’s crucial, because decent mascaras also apply easily and evenly.
Before an ingredient can be included in products that we apply to our skin (or ingest as medicine, for that matter), it has to be established that it’s safe to do so. Health and safety information was reviewed before concluding that polyoxyl 40 stearate is safe for us to use, but when using the product, it’s best to use as directed and try to remember that we can always talk to a grown-up when we don’t know or have questions about what we are putting in our mouth.
Among the reasons products would contain polyoxyl stearate is because it can help products work better and feel better on our skin. But, there are those who are allergic to this ingredient, so always read a label and ask a grown-up if we’re not sure if the product isn’t safe for us to use. All in all, polyoxyl 40 stearate is a very helpful ingredient that helps make a number of things we have safer and healthier to use in our everyday lives.
