What Is Perlite?
Perlite is a natural rock that looks gray or black and doesn't have a smell. It's used in cosmetics to help absorb things and make products thicker. However, it may contain small amounts of something called crystalline silica dust, which can be bad for your health if you breathe it in too much.
What is the purpose of Perlite in personal care products?
It is used for its absorbent
and bulking characteristics.
Perlite absorbs liquid and increases volume or weight.
What Are Absorbent Ingredients?
Perlite has absorbent characteristics.
Absorbent ingredients are substances added to products to help them absorb moisture or oil. For example, in a face powder, absorbent ingredients like talc or silica help to absorb excess oil on the skin and give a matte finish. In deodorants, absorbent ingredients like baking soda or cornstarch helps to absorb sweat and moisture.
Besides cosmetic items, absorbent ingredients are found in other products like diapers. Super-absorbent polymers (SAPs) help keep babies dry by quickly absorbing and locking away moisture.
Types of Absorbent Ingredients
Here are some of the most common types of absorbent ingredients in cosmetics:
Powders: Cosmetics may contain a variety of powders, such as talc, cornstarch, or silica, which can help to absorb excess oil or moisture from the skin.
Clays: Natural clays, such as kaolin or bentonite, are often used in cosmetics as they can absorb excess oil and unwanted substances from the skin.
Charcoal: Activated charcoal is sometimes used in cosmetics as it can absorb impurities and toxins from the skin.
Gels: Some gels, such as aloe vera gel, can have absorbent properties and may be used in cosmetics to help soothe and moisturize the skin.
Polymers: Certain polymers, such as polyacrylates or cross-linked polyethylene, can be used in cosmetics to absorb excess moisture from the skin or to create a smooth, matte finish.
What Are Bulking Ingredients?
Perlite has bulking characteristics.
Bulking ingredients are substances used in products to increase their volume or weight. They are usually added to products like lotions, creams, and shampoos to make them thicker and more substantial.
Bulking ingredients can also help to stabilize the product and prevent it from separating. They may be natural, like plant-based gums, or synthetic, like polyethylene glycols (PEGs) or microcrystalline cellulose.
Bulking ingredients can sometimes dilute active ingredients, making them easier to apply to the skin. It can be instrumental in skincare products like serums or spot treatments, where high concentrations of active ingredients can be too strong for the skin.
Bulking Ingredients in Other Products
Bulking agents are also used in other products besides cosmetics. In the food industry, bulking agents increase the volume of products like bread, cakes, and sauces. They often substitute for high-calorie ingredients like sugar or fat, lowering the products' calories while maintaining their texture and taste.
In the pharmaceutical industry, bulking agents produce tablets and capsules. They help increase the final product's volume and make it easier to handle during the manufacturing process. Bulking agents can also adjust the release rate of active ingredients in the body, providing a sustained or controlled release effect.
Types of Bulking Ingredients
Here are some of the most common types of bulking ingredients in cosmetics:
Powders: Cosmetic powders such as talc, mica, and silica are often used as bulking agents to add volume to a product.
Polymers: Polymers such as polyethylene and polypropylene are often used as bulking agents because of their ability to absorb water and swell in size.
Fatty acids: Fatty acids such as stearic and palmitic acids are used as bulking agents in cosmetic formulations to add texture and viscosity.
Glycerin: Glycerin can act as a bulking agent by adding volume and texture to cosmetic products.
Waxes: Waxes such as beeswax, carnauba wax, and candelilla wax are used as bulking agents in cosmetics to add thickness and texture.
Emollients: Emollients such as mineral oil, petrolatum, and lanolin can also act as bulking agents by adding volume and texture to a product.
