What Is Hydrated Silica, From a Chemistry Standpoint?
To put it simply, hydrated silica is a compound of silicon and oxygen – more precisely, silicon dioxide. In its natural state, it’s found in the form of opal or diatomaceous earth. When combined with water, it forms a gel. This gel is what’s used in many commercial products, including toothpaste and skincare products.
The Benefits of Hydrated Silica for Your Teeth
Hydrated silica is often used as a mild abrasive in toothpaste. Abrasives are necessary to remove plaque and debris from your teeth. They work by physically scrubbing away these deposits. Hydrated silica is a good choice for an abrasive because it’s gentle and effective. Here’s what it can do for your teeth:
- scrub away dental plaque;
- remove stains caused by coffee, tea, or smoking;
- prevent cavities;
- keep your breath fresh.
At the same time, hydrated silica is chemically inert, meaning it won’t interact with other ingredients in your toothpaste. This makes it a safe choice for people with sensitive teeth or gums. In fact, diatomaceous earth (the natural form of hydrated silica) has been used for centuries as a tooth-cleaning agent.
How to Use Toothpaste With This Ingredient?
To get the most out of hydrated silica without damaging your enamel, use a soft-bristled brush and fluoride toothpaste. Apply the paste to your brush, then gently brush your teeth in a circular motion for two minutes. Spit the paste out – you don’t need to rinse your mouth with water. You can brush your teeth twice a day, and be sure to visit your dentist for regular checkups.
Avoid using hard toothbrushes, as they can damage your enamel, especially when paired with an abrasive toothpaste. Also, don’t brush too hard – hydrated silica is effective even when used gently.
Hydrated Silica in Other Personal Care Products
While toothpaste is its main commercial use, hydrated silica is also added to a variety of other personal care products, including shampoos, conditioners, soaps, and deodorants. It’s often used as a thickening agent or to absorb excess oil.
In shampoos and conditioners, hydrated silica can help remove buildup from your hair and scalp. In soaps, it can act as a gentle exfoliant. And in deodorants, it can help absorb sweat and keep you feeling fresh all day long.
Makeup lovers will be happy to know that hydrated silica is also a common ingredient in pressed powders and eye shadows. Its anti-caking properties help keep these products looking smooth and free of clumps. It also makes the texture of these products more velvety and smooth.
Other Interesting Uses
We’ve covered what hydrated silica does in cosmetics, but that’s not all this versatile substance can do. It’s also used in the production of beer, as a desiccant (to absorb moisture), and even in paints and varnishes. When combined with magnesium hydroxide or aluminum hydroxide, it can act as a flame retardant.
Is Hydrated Silica Safe for Your Health?
There’s no evidence to suggest that hydrated silica is harmful to your health. In fact, it’s considered a safe ingredient for personal care products. The FDA has classified it as GRAS (generally recognized as safe). Because it doesn’t react with other ingredients, it’s also unlikely to cause any skin irritation or allergic reactions.
So, what’s the point of hydrated silica? As you can see, it has a variety of uses that make it a valuable ingredient in many personal care products. It’s safe, gentle, and effective – everything you could ask for in a skincare ingredient. So next time you see it listed on the label of your favorite toothpaste or powder, you’ll know exactly what it does.
