When it comes to makeup, one ingredient that often raises concerns is titanium dioxide. With its prevalence in various cosmetic products, including foundation, lipstick, and eye shadow, many people wonder about its safety. In this article, we will delve into the potential concerns surrounding titanium dioxide and explore its uses in makeup. So, is titanium dioxide safe in makeup? Let’s find out.

But before we dive into the details, let’s take a step back and understand what titanium dioxide is. Titanium dioxide is a naturally occurring mineral commonly used as a colorant and UV filter in cosmetics. It has excellent light-scattering properties and provides opacity, making it a popular choice for achieving desirable shades and coverage in makeup products. However, as with any ingredient, understanding its potential risks and limitations is crucial.

The Common Concerns Surrounding Titanium Dioxide

Before we discuss the safety of titanium dioxide in makeup, let’s address some of the common concerns associated with this ingredient.

Ingredient Concerns

One of the primary concerns about titanium dioxide revolves around its possible absorption by the skin. While there is limited evidence to suggest enhanced penetration, it is essential to consider this factor. Additionally, titanium dioxide is classified as a possible human carcinogen, although the evidence of its carcinogenicity is also limited. These concerns have led to further scrutiny and regulations regarding its usage in cosmetic products.

Products with Titanium Dioxide

Titanium dioxide is found in a wide range of cosmetic products, including foundation, lipstick, and eye shadow. It is also a common ingredient in sunscreen, toothpaste, and paint. This ubiquity of titanium dioxide in day-to-day products emphasizes the importance of understanding its potential risks and benefits.

Enhanced Skin Absorption

One concern surrounding titanium dioxide is its potential for enhanced skin absorption. However, studies have shown that when applied to intact skin, titanium dioxide does not penetrate the skin barrier. This finding suggests that the risk of systemic exposure is minimal when using cosmetics containing titanium dioxide.

No Absorption into Intact Skin

Research has demonstrated that titanium dioxide particles are too large to pass through the outermost layer of the skin, called the stratum corneum. This layer acts as a protective barrier, preventing the absorption of most particles, including titanium dioxide. Therefore, when applied topically, titanium dioxide primarily remains on the surface of the skin.

Occupational Hazards

Another aspect to consider is the occupational hazards related to titanium dioxide. Occupational exposure to titanium dioxide powder during manufacturing processes has raised concerns. However, regulations are in place to ensure that workplace exposures remain restricted to low doses, minimizing potential health risks for workers.

Allowed Workplace Exposures Restricted to Low Doses

Given the concerns surrounding occupational exposure, authorities have established guidelines to control and limit the amount of titanium dioxide in the workplace. These regulations help protect workers from excessive exposure and ensure their safety.


The classification of titanium dioxide as a possible human carcinogen has given rise to concerns. While research indicates limited evidence of its carcinogenicity, it is crucial to consider this aspect. Further studies are needed to fully understand the potential risks associated with prolonged exposure to titanium dioxide.

Possible Human Carcinogen

Titanium dioxide is classified as a Group 2B possible human carcinogen by the International Agency for Research on Cancer (IARC). This classification signifies that there is limited evidence of titanium dioxide’s carcinogenicity in humans.

Limited Evidence of Carcinogenicity

It’s important to note that the evidence regarding the carcinogenicity of titanium dioxide is still limited. While further research is necessary, regulatory agencies continue to monitor and evaluate the safety of this ingredient.

Decreased Skin Absorption

Contrary to the concerns surrounding enhanced skin absorption, studies have shown that titanium dioxide generally has a decreased absorption rate.

No Absorption into Intact Skin

As mentioned earlier, titanium dioxide particles are generally unable to penetrate the stratum corneum, which acts as a barrier against foreign substances. Therefore, when applied topically, titanium dioxide tends to stay on the surface of the skin, minimizing the risk of absorption.

Multiple, Additive Exposure Sources

It is important to consider that exposure to titanium dioxide can occur from various sources apart from cosmetics. This compound is designated as safe for general or specific, limited use in food, further contributing to potential exposure.

Designated as Safe for General or Specific, Limited Use in Food

The safety of titanium dioxide as a food additive has been evaluated by regulatory authorities. Based on the available data, it is considered safe for general or specific, limited use in food products. This means that the exposure to titanium dioxide can occur not only through cosmetics but also through the consumption of certain foods.


When assessing the safety of titanium dioxide in makeup, it is important to consider the recommendations provided by industry and government organizations. These recommendations are designed to ensure the safe use of cosmetic products containing titanium dioxide.

Industry or Government Recommendations for Safe Use

Various regulations and guidelines have been put in place to ensure the safe use of titanium dioxide in cosmetics. It is crucial for cosmetic companies to adhere to these recommendations to protect consumer health and safety.


While the potential effects of titanium dioxide on human health are a concern, it is also important to consider its impact on the environment. Fortunately, titanium dioxide is not suspected to be an environmental toxin.

Not Suspected to be an Environmental Toxin

According to available data, titanium dioxide does not pose significant toxicity risks to the environment. However, proper disposal practices and wastewater treatment methods should still be followed to minimize environmental impact.

Persistence and Bioaccumulation

Titanium dioxide is not suspected to be bioaccumulative, further supporting its safety in makeup products.

Not Suspected to be Bioaccumulative

Unlike some substances that tend to accumulate in living organisms over time, titanium dioxide does not exhibit significant bioaccumulation potential. This attribute contributes to its overall safety profile.

Data Gaps

While considerable research has been conducted on titanium dioxide, there are still data gaps that need to be addressed to fully understand its toxicity.

21,244 Studies in PubMed Science Library May Include Information

To date, there have been thousands of studies conducted on titanium dioxide, which are available in the PubMed science library. Researchers continue to explore the potential toxic effects of this compound to fill in existing data gaps.

Understanding Scores

When it comes to assessing the safety of cosmetic ingredients, various scoring systems and databases are available. These platforms evaluate the potential hazards and risks associated with different compounds, including titanium dioxide. The Hazard Score indicates the potential risks, while Data Availability reflects the amount of research and data available for a specific ingredient.

Hazard Score

The Hazard Score for titanium dioxide in makeup varies across different scoring systems. It is crucial to refer to reputable databases and consider multiple sources when evaluating the hazard levels associated with this ingredient.

Data Availability

The availability of data on titanium dioxide provides researchers and regulatory authorities with valuable information to assess its safety. The extensive data available in the PubMed science library highlights the significant research conducted on this compound.
