Cosmetics are often touted for their ability to enhance our appearance and make us feel beautiful and confident. However, there is a hidden danger in some of these products that you can’t ignore: mica . Mica is a mineral substance used as a pigment in many cosmetic products such as eye shadow, foundation, and lipstick. However, this mineral can be problematic due to its source and production. Mica is typically mined, often in developing countries where working conditions and environmental standards are far below those in developed countries. Mica miners, including children, are often exposed to dangerous conditions, working long hours in unsanitary mines and risking fatal accidents. Additionally, mica mining can also lead to environmental damage such as deforestation and habitat destruction. Understanding the hidden dangers of mica in cosmetics is crucial to making ethical and responsible beauty choices.

What is mica?

Mica is a naturally occurring mineral that is widely distributed in the Earth's crust. It is characterized by a thin, flexible sheet structure that makes it ideal for many industrial and cosmetic applications. Mica comes in several varieties, including muscovite mica, phlogopite mica, and biotite mica, which differ in their chemical composition and physical properties.

The issue of mica safety in cosmetics has attracted significant attention, primarily due to concerns about the ethics of its sourcing rather than its potential toxicity. From a health perspective, mica used in cosmetics is considered safe. The particles are large enough not to penetrate deep into the skin, minimizing health risks. In addition, mica used in cosmetic products is carefully purified and processed to remove any impurities, ensuring a high level of safety for consumers.


This mineral is valued for its unique qualities, including its brilliance , transparency, heat resistance and low coefficient of friction. These characteristics make it an ingredient of choice for many products, ranging from electrical coatings to makeup products to paints and plastics.


In the cosmetics industry, mica is widely used as a pigment to add shine and color to a variety of beauty products, such as eye shadows, blushes, lipsticks, and loose powders. Due to its reflective properties, mica imparts a luminous, iridescent effect that is highly sought after in high-end makeup products.

One of the main concerns is the potential presence of asbestos in some mica deposits. Asbestos is a fibrous mineral known for its adverse health effects, causing serious respiratory diseases such as asbestosis and lung cancer. Although strict regulations now govern the use of asbestos, residual traces can still be found in some batches of mica , posing a risk to workers and consumers.



While mica on skin is “fairly” safe, the concerns surrounding it are ethical, due to its sourcing rather than its potential toxicity. The particles are large enough that they do not penetrate deep into the skin, minimizing health risks. Additionally, mica used in cosmetic products is carefully purified and processed to remove any impurities, ensuring a high level of safety for consumers.

The real problem with mica in cosmetics

The ethical problem

Although mica is generally considered safe when used in cosmetic products, concerns have been raised about the health risks associated with its use. The real problem lies in the process of extracting and processing mica, which can expose workers to hazardous working conditions and toxic substances.

In addition, mica mining can also expose miners to other toxic substances, such as crystalline silica, which can lead to long-term respiratory problems. Additionally, working conditions in mica mines, often located in developing countries, can be extremely poor, with high risks of accidents and occupational diseases.


The Hidden Dangers of Mica in Cosmetics

Beyond the health risks, the use of mica in cosmetics also raises ethical and environmental concerns. Indeed, much of the mica used in the cosmetics industry comes from mines located in developing countries, mainly India, where labor and environmental protection standards are often lax.


A particularly worrying issue is the exploitation of children in mica mining. Numerous reports have highlighted the presence of children, sometimes very young, working in extremely dangerous and unsanitary conditions to extract this mineral. These children are exposed to high risks of injury, disease and exploitation, in addition to being deprived of an education and a childhood.


Beyond the exploitation of workers, mica mining also has negative impacts on the environment. Mica mining can lead to deforestation, destruction of natural habitats, and pollution of soil and water. These environmental impacts can have disastrous consequences on ecosystems and local communities, threatening their health and way of life.


The environmental impact of mica mining

Mica mining, in addition to ethical issues related to working conditions, also has harmful consequences for the environment. Mica mines, often located in remote and fragile regions, can cause serious ecological damage.


Deforestation is one of the main impacts of mica mining. To access deposits, miners often have to clear large areas of forest, destroying entire ecosystems and threatening biodiversity. This loss of forest cover can also contribute to soil erosion and disruption of the water cycle, with disastrous consequences for local communities.


In addition, mica mining can lead to soil and water pollution through the release of chemicals, dust and mining waste. These contaminants can harm the quality of drinking water, threaten crops and wildlife, and negatively impact the health of local populations. The environmental impact of mica mining is therefore a major concern that must be taken into account in the production of cosmetic products.

Regulations and standards governing the use of mica in cosmetics

In response to growing concerns about the dangers of mica in cosmetics, efforts have been made to establish regulations and standards to govern its use. However, these measures are still insufficient to ensure ethical and sustainable practices throughout the supply chain. At the regulatory level, the use of mica in cosmetic products is generally subject to national and international regulations, which set limits and requirements in terms of quality and safety.

  • In the European Union, European Cosmetic Regulation (EC) No 1223/2009 regulates the use of cosmetic ingredients, including mica, by imposing controls and restrictions.
  • In Canada, there are no specific regulations for mica like in the European Union with Cosmetic Regulation (EC) No. 1223/2009. However, the use of mica in cosmetics is regulated by Health Canada through the Food and Drugs Act and the Cosmetic Regulations, which impose safety standards and require that ingredients are safe for their intended use. Companies must ensure that their products meet these standards, particularly in terms of transparency and ingredient safety.


How to avoid cosmetics containing mica

Given the potential dangers of mica in cosmetics, it is important for consumers to take steps to limit their exposure to this mineral. Here are some tips for avoiding products containing mica:

  • It is essential to carefully read the ingredient lists of cosmetic products and look for the presence of mica or its derivatives, such as potassium aluminum silicate. Avoid products that contain these ingredients, especially makeup products such as eye shadows, blushes, and loose powders. To learn how to read cosmetic ingredient lists, check out our article on this subject .
  • Next, favor cosmetic brands that are committed to transparency and traceability of their ingredients. For our part, as a member of the Green Pages of Quebec, we had to take this step. https://lespagesvertes.ca/ . Some companies have implemented responsible mica sourcing policies, guaranteeing ethical working conditions and limited environmental impact. Find out about the brands' practices before purchasing their products.
  • Finally, opt for alternatives to mica, such as natural mineral pigments (iron oxide, titanium dioxide, etc.) or plant pigments (fruit and vegetable powders, plant pigments, etc.). These ingredients can offer similar results in terms of shine and color, while being more respectful of the environment and health. Products containing clays also offer excellent alternatives.

Alternatives to mica in cosmetics: marketing?

Radio-Canada's On dira ce qu'on veux podcast shows that several large companies are taking steps to be more transparent about the use of micas in their products. At least, these companies assure consumers that the micas used are from "ethical" sources. The vast majority of eyeshadows contain mica, including those from major brands like Nars, Fenty Beauty (Rihanna) and Too Faced.

Since it is impossible to know the exact origin of the mica used, it cannot be assumed that it was ethically mined.

Excerpt from: We will say what we want - Radio-Canada podcast

While brands like Lush have replaced mica with synthetic alternatives, it can be hard to tell if this is just ethical marketing. Lush has developed a synthetic mica that offers the same glow, but its highlighter is not available in Canada, except through the UK platform.

Still according to the Radio-Canada podcast, "the Estée Lauder group, which owns the brands M·A·C, Too Faced, Smashbox and Clinique, funds schools in "at-risk" villages. The initiative has however been criticized and perceived as a public relations operation to allow the group to stand out." Large companies know very well how to use this "ethical" aspect to attract consumers , which raises questions about the sincerity of these approaches.

The use of mica in cosmetics raises serious health, ethical and environmental concerns . This mineral, although widely used in the beauty industry, actually hides many dangers related to its extraction and processing. Health risks, such as exposure to asbestos or toxic substances, as well as deplorable working conditions in mica mines, including the exploitation of children, are all reasons to question the use of this ingredient in cosmetic products. In addition, the environmental impact of mica extraction, with deforestation and pollution of ecosystems, raises crucial questions about the sustainability of this industry.


Consumers need to become more conscious by choosing ethical brands and alternatives to mica. At La Sultana, we have decided to reduce or even phase out the use of mica. Although many judge the quality of products by their shiny appearance, we believe that over time, we can change this perception by educating our customers.
