What is Titanium Dioxide, and How is it Used in Supplements and Skin Care Products?

Titanium dioxide is a white-colored compound with various uses, from industrial applications to consumer products. Its chemical name is TiO2 or E171 when employed as a food additive.

Titanium dioxide has become increasingly popular in recent years, as it found its way into dietary supplements and skin care products due to its unique properties [1]. As a supplement, titanium dioxide can help promote healthy skin, hair, and nails by providing the body with essential vitamins and minerals. Titanium dioxide has also become an important ingredient in cosmetics for its ability to protect the skin from environmental damage [2]

Titanium dioxide serves for its nutritional benefits and cosmetic properties.

Benefits of Titanium Oxide in Skincare Products and Supplements

  • Titanium Dioxide provides broad-spectrum UVA and UVB protection, helping to prevent damage from sun exposure, which can lead to premature aging, wrinkling, and skin cancer [3]
  • Titanium Dioxide acts as a sunscreen filter by reflecting light away from the skin and absorbing ultraviolet radiation before it penetrates the deeper layers of the skin [4]
  • Titanium Dioxide is an anti-inflammatory agent that can soothe irritated and inflamed skin caused by environmental stressors such as heat and wind [5]
  • Titanium Dioxide has antibacterial properties that help protect the skin from infection due to its ability to absorb sweat and oils on its surface, keeping it clean and healthy [6]
  • Titanium Dioxide is a natural antioxidant that helps reduce free radical damage caused by exposure to harmful chemicals in skincare products or environmental pollutants such as smog or smoke [7].
  • Titanium dioxide also serves as a whitening agent when used in facial creams and lotions, helping to even out pigmentation issues that can cause discoloration or blotchiness in some areas of the face [8]
  • In addition to its skincare benefits, titanium dioxide is also found in many dietary supplements because it has been known to aid digestion, promote bone health, improve heart health, boost immunity, and provide other general health benefits. 

Is Titanium Dioxide Safe for Use in Everyday Life?

The answer is a resounding yes! 

Titanium Dioxide is safe for use in everyday life. Titanium dioxide, a naturally occurring oxide of titanium, exists in various common foods and products. The FDA has approved it as a food color additive, and it finds application in dietary supplements and medications.

As an ingredient in cosmetics, titanium dioxide works as a pigment that provides whiteness and brightness to products like toothpaste, makeup, and sunscreen. Products such as paint, paper, plastics, rubber, ink, and textiles also use it.

Titanium dioxide has been extensively studied for potential toxicity concerns. Many studies have concluded that titanium dioxide poses no health risks when used according to instructions given by its manufacturer [9]. There is also evidence that suggests long-term exposure to titanium dioxide may not cause any adverse effects on human health or the environment. 

What Levels of Exposure to Titanium Dioxide are Considered Safe?

Like any chemical substance, there is a level of exposure that should not be exceeded in order to ensure safety. 

While it is generally considered safe, research suggests that inhaling high levels of titanium dioxide may pose health risks, especially among those working in industries where exposure is common [10]

Rest assured that regulatory authorities monitor and regulate titanium dioxide exposure levels in everyday products, ensuring guilt-free enjoyment of your favorite sunscreen or white chocolate.

How Can You Ensure that You’re Using Titanium Dioxide Safely?

It is important to use Titanium Dioxide safely to prevent potential health risks. The first step to ensure safety is to always read the labels on the products you purchase. It is also important to use protective gear like gloves and masks when handling titanium dioxide powder in its raw form.

If you work in an industry that uses titanium dioxide, make sure you follow the safety guidelines outlined by your employer. Finally, never ingest titanium dioxide, as it can cause harm to your health. With these safety measures in place, you can confidently use titanium dioxide without any worries [11].  

Things to Consider Before Purchasing Skincare or Supplement Products with Titanium Dioxide as an Ingredient

Before purchasing any product that contains titanium dioxide, it is important to consider the following:

  • Titanium dioxide can be harmful when inhaled, so if the product is in the form of a powder or spray, it is best to avoid using it or to use it with caution
  • If you have sensitive skin, titanium dioxide may cause irritation or allergic reactions
  • Perform a patch test before using it all over your face or body.
  • Be mindful of the amount of titanium dioxide in the product, as excessive use can result in skin damage 
  • Read the ingredient list and research beforehand to find the right skincare or supplement product for your needs.

Potential Health Risks Associated with Titanium Dioxide Exposure

  • Respiratory irritation: Titanium dioxide is a particulate matter, so it may cause airway inflammation and breathing difficulties when inhaled
  • Cancer: Titanium dioxide nanoparticles may cause DNA damage, which could lead to cancer
  • Allergic reactions: People with allergies or asthma may be at increased risk of developing an allergic reaction to titanium dioxide particles
  • Immune system disruption: Exposure to titanium dioxide nanoparticles could potentially interfere with the body’s natural defense mechanisms, leading to an impaired immune response
  • Reproductive toxicity: High levels of titanium dioxide have been linked to reproductive toxicity in animals, with no studies conducted on humans as of yet.

  • Oxidative stress: Titanium dioxide particles can generate reactive oxygen species (ROS), which are highly reactive molecules that can cause oxidative stress and tissue damage in the body if left unchecked by the body’s natural defenses

So, is Titanium Dioxide in Supplements and Skincare Products Safe?

Titanium dioxide is quickly becoming a popular ingredient in many skincare and supplement products due to its effective ability to protect the skin. 

Despite the potential adverse effects if consumed at higher levels than recommended, titanium dioxide found in cosmetic, sun care, and dietary supplement products is generally safe when used appropriately [12]

However, it still crucial to ensure the safe use of products containing titanium dioxide by thoroughly researching their formulations and paying special attention to avoiding overexposure to other elements in the product.

Before adding any product with titanium dioxide as an ingredient to your routine, consider the risks and benefits that come with it to determine whether or not it is right for you.
