In fact, even if you&#;ve never been much of a makeup buff, you&#;ve probably still come in contact with the ingredient via your shampoo or shaving cream. It&#;s probably in your foundation, as well as your toaster and car paint.
In recent years, mica has become controversial because child labor may be used in its mining process. Although some beauty companies are working towards sourcing the ingredient ethically, finding alternatives isn&#;t so easy for those looking to avoid it altogether.
Mica is used to thicken and add shimmer to the following beauty products:
What Is Mica Powder?
Mica is the name of a group of minerals that come from sheet silicate. There are 37 types and can be found in granite, slate, phyllite, and shale.
Mica powder is lightweight and flexible. It&#;s resistant to heat, which makes it a favorite material for the electronic industry. However, it&#;s the pearly luster of its flakes that make it popular in cosmetics and skin care products.
It&#;s primarily used as a colorant but is also a mild abrasive, as well as a thickening and smoothing agent. Mica is naturally reflective and the reason why highlighter &#;lights&#; up brow bones and eyeshadow sparkles.
Beauty chemists combine it with other ingredients to create different effects. Smaller bits can be added to powders to create a smoother but illuminating finish.

Synthetic Mica vs. Natural Mica
While natural mica powder comes from rocks, synthetic mica is made in a lab. It&#;s also known as synthetic fluorphlogopite, and is created from magnesium aluminum silicate sheets.
The process includes melting manganese, metal, and aluminum, and then cooling to produce a crystal. From there it can be ground into a powder.
One of the benefits of using synthetic mica, according to companies like Lush, is that it&#;s purer and can achieve brighter colors because of its particle size. Organic mica is not as refined.
Synthetic mica may appear in ingredients lists under the following names:
According to the Environmental Working Group's Skin Deep Database, neither ingredient is considered environmentally toxic or harmful to the body. However, information regarding synthetic mica is limited, and according to the Journal of Occupational and Environmental Medicine, the dust from natural mica powder has been shown to cause respiratory issues in workers.
One huge benefit of synthetic mica is that it side-steps the need for mining altogether. A investigation by the Thompson Reuters Foundation revealed that several children were killed while working in illegal mica mines in India. The use of child labor in the extraction of the mineral has led to more companies opting to use its synthetic counterpart.

According to a report from Zion Market Research, the global mica market is expected to reach $727 million by . There are two divisions of the industry: flake mica mining and sheet mica mining.
Flake mining largely serves the electronic, rubber, and construction industry. Once extracted from placer deposits and pegmatites, mica is ground and used as a pigment extender for paint, filler, and reinforcing agent. There are mines across the U.S., half of them being in North Carolina.
Sheet mica is the mineral of choice for cosmetic companies. It&#;s gathered through open-pit surface mining. There are mines throughout the world, including China, Brazil, and Madagascar. The beauty industry heavily relies on mica from India, which exported $71.3 million worth of the mineral in .
According to the investigation from the Thompson Reuters Foundation, 70% of the mines operating in India are illegal. There are mines in Andhra, Pradesh, Maharashtra, Bihar, and Jharkhand.
Bihar and Jharkhand are part of what is sometimes referred to as the &#;mica belt.&#; It&#;s a region that&#;s home to mines that often employ children who are small enough to fit into cave openings. According to a survey from India&#;s National Commission for Protection of Child Rights, some of the children working in the mines are as young as six.
Work is labor-intensive, requiring miners to move down narrow tunnels that sometimes collapse. In non-commercial settings, mica is separated from the rock by hand with the use of pry bars and hammers.

Injuries and deaths are not often reported by workers or families. Many mines are located in impoverished areas, where collecting mica is the main source of income.
One of the drivers of illegal mining in India is the country's Forest Conservation Act. Many of India&#;s mines are located in protected forests, making it difficult for legal leases to be acquired. This has led villages to collect mica from abandoned mines in the area.
While the mica belt has received the brunt of attention from child welfare advocates, a report from Terre des hommes showed similar practices happening in Pakistan, Sudan, China, and Brazil.
Most recently, attention has been on mica mining in Madagascar. It&#;s reported that 10,000 children there are miners.
Is Mica Powder Sustainable?
Natural mica is not renewable, making sustainability complicated. While electronics containing mica can be recycled and reused, the same cannot be said for body washes or beauty products.
While there hasn&#;t been a ton of research on the environmental impact of mica mining specifically, the mining industry has been shown to be disruptive to ecosystems. Some of the potential impacts of mining include deforestation, contamination of local water, dust emissions, and increased noise pollution.
From an environmental and sustainability perspective, synthetic mica may be more friendly&#;and it doesn't put children at risk. However, other industries haven&#;t been able to utilize synthetic mica the way that the cosmetic industry has.
Although synthetic mica may be more sustainable to produce, it&#;s not as affordable as natural mica. It&#;s also manufactured in China and Japan, meaning it still needs to be exported to other parts of the globe.
Can Mica Powder Be Ethically Sourced?
With child exploitation being common, natural mica powder is not the most ethical ingredient. However, completely stopping mining may create other problems, as it is often the sole source of income for families in production areas.
Since the incidence of child labor has been exposed, more beauty companies have taken concrete steps to source the ingredient ethically. Companies like Chanel, Burts Bee's, Coty, and Sephora have become members of the Responsible Mica Initiative (RMI), an organization working to create responsible (and traceable) mica chains. Its goals are to end child labor and create work environments that follow legal mandates. Other companies have decided to rely on synthetic mica.
Mica pigment is a dazzling, glittering addition to a wide array of products, sought after for both its aesthetic and functional qualities. This mineral-based colorant is a secret ingredient in everything from eye shadow and epoxy art to automotive paints and ceramic glazes.
Those in the arts and crafts industry, particularly artists and epoxy companies, are always looking to deepen their knowledge and harness the remarkable potential that mica pigments bring to their creative process. In this extensive guide, we&#;ll give you a better understanding of the composition and properties of mica pigment and shine a light on its many uses.
When wandering the colorful pathways of a paint or craft store, you&#;re likely to encounter bottles of luminous pigments designed to add shine and charm to any project. Amidst these options, mica pigment stands out with its shimmer. Mica pigment, made from a mineral that manufacturers purify and crush into a powder, bears a natural glittering quality, echoing the sparkles of its original rock form.
A versatile member of the mineral family, many people know mica for its glittering properties that come in a variety of colors. When ground into a fine powder, mica transforms into a versatile pigment with a lustrous finish. Its reflective qualities have made it a staple in cosmetics, where it's prized for creating a range of effects, from the subtly radiant to the boldly metallic.
To gain a fuller understanding of mica pigment, one must learn about its elemental makeup. Mica is a group of sheet silicate minerals known for their high chemical stability, large aspect ratio, and softness. Its composition is a combination of various minerals, the most common being silicate sheets, aluminum, potassium, and trace amounts of iron, magnesium, and water.
When turning mica into pigment, a careful extraction and purification process ensures that the mica particles are uniform, fine, and free of impurities. This crucial step helps prevent any inconsistencies that could affect the pigment&#;s quality and behavior.
The properties of mica pigment are as diverse as its usage, making it a sought-after material for a myriad of applications. Let&#;s dive into the most distinct properties of mica pigment:
Mica pigment is highly reflective, giving off an iridescent shine when exposed to light. Its reflective properties can vary depending on the particle size, with finer particles often providing a more brilliant effect.
Despite being reflective, mica pigment is mostly transparent. This translucent nature allows it to blend seamlessly with the medium it's mixed into, creating a smooth and even finish.
Mica's sheet-like structure also imparts thermal insulation properties, making it an ideal pigment for applications exposed to high temperatures, such as automotive paints and ceramic glazes.
Electrical manufacturers use mica for its exceptional electrical resistance, which makes it a key ingredient in insulators and electronic coatings.
