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.

Beauty Products That Contain Mica

Mica is used to thicken and add shimmer to the following beauty products:

• Bronzer and highlighter
• Lipstick and lip gloss
• Eye shadow and mascara
• Concealer, foundation, makeup primer, and facial serum
• Blush and facial powder
• Nail polish
• Daily use SPF
• Men&#;s shaving cream and baby shampoo

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.

If you check out the ingredient list of your lipstick or body bronzer, you may find it listed as:

• C
• Micagroup Minerals
• Pigment White 20
• Sericite
• Sericite GMS-ZC
• Sericite GMS-C
• Sericite MK-A
• Sericite MK-B
• Golden Mica
• Muscovite Mica

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:

• Fluorphlogopite
• Fluorphlogopite (MG3K[ALF2O(SIO3)3])
• Synthetic Fluorphilogopite
• Synthetic Fluorphlogopite

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.

Introduction to

Pigmently

Welcome to Pigmently, our online store for high-quality mica powder pigments and liquid dyes.

Because our store specializes in mica powder, it seems prudent to write an article on the fundamentals of mica powder and mica minerals.

In this article, we'll go over what mica minerals are, then we'll explain what mica powder is, how it's made, and the benefits of using it as a colorful powder pigment.

What Is Mica?

Before we dive into understanding mica powder, let's first uncover what mica is. Mica is a naturally occurring group of silicate minerals known for their perfect basal cleavage, which is the tendency for some minerals to be broken in certain shapes with a side that is smooth. What this means for mica is that these minerals can be split into thin, flexible, and elastic sheets. Mica can be found throughout the earth's crust.

There are 37 different types of mica mineral. The most common of these are muscovite and phlogopite, primarily used for their utility in construction and composite materials.

Mica is valued for several remarkable properties. It is heat-resistant, electrically insulating, and optically active. These characteristics make it an incredibly versatile mineral, used in a variety of industries, including electronics, cosmetics, and of course, as pigments in arts and crafts.

But how do these minerals turn into the shimmering powder we love to use in our art projects? Let's find out.

What is Mica Powder?

Now that we know what mica is, it's time to understand what mica powder is. Mica powder is essentially mica that has been ground into a fine powder. It retains all the beautiful properties of mica, including its shimmering appearance, which can range from a subtle shine to a more glittery effect. This is due to the light-reflecting properties of mica.

Mica powder is often mixed with colorful additives to produce vivid shades of various colors. Because mica itself has a limited range, these additives&#;which can be natural or synthetic&#;give it that vibrant boost that takes it from good to great.

From vibrant blues and rich greens to subtle pinks and bold reds, mica powder can be found in a myriad of hues. But it doesn't stop there. Mica powder is also safe for the skin, making it a popular choice in the cosmetics industry for products like eyeshadow, nail polish, and lip gloss. Keep in mind this doesn't necessarily apply to any additives, so it's important to confirm what's in it before using a mica powder for cosmetic purposes.

How Is Mica Powder Made?

The process of making mica powder is fairly straightforward. It starts with extracting mica from the earth, which often involves mining with heavy machinery. Once the mica is extracted, it's then cleaned and dried. After drying, the mica is ground into a fine powder. This process may be repeated several times until the intended particle size is achieved.

Once the mica has been ground into a fine powder, it's then often mixed with other minerals and compounds. These blends can create a wide range of colors, providing artists with a broad palette to work with. So, whether you're looking to add a pop of color or a subtle shimmer to your project, mica powder is a great way to go.

Mica Powder Pigments: What Are They?

Mica powder pigments are just mica powder that has been blended with other substances to create distinct and vivid colors. These pigments can be mixed with a variety of mediums, including paint, resin, and even soap, to create vibrant, shimmering effects.

These pigments are known for their excellent color stability, meaning they won't easily fade over time. This is in contrast to many other types of pigments that can lose their color over time or when exposed to sunlight. So, not only do mica powder pigments bring beautiful shimmer and color to your projects, but they also ensure longevity.

Benefits of Using Mica Powder in Your Art

There are many benefits to using mica powder in your art. First and foremost is the beautiful, shimmering effect it can bring to your projects. Whether you're painting, making jewelry, or crafting homemade soap, mica powder can add a touch of magic to your work.

Another benefit of mica powder is its versatility. As mentioned earlier, mica powder can be mixed with various mediums, allowing for a wide range of applications. They're often very potent, too, so a little goes a long way, giving you much control over the intensity of the colors you use. Additionally, because mica powder pigments are stable, they're a great choice for projects that will be exposed to light or heat.
