The paints industry has developed myriad chemicals to enhance the product shelf life, color, texture and other properties. These paints are made from a few chemicals that are especially suited for this industry. Many of these are volatile organic compounds (VOCs), which vaporize as soon as they are exposed to the atmosphere. They also contain heavy metals such as arsenic, lead and chromium. VOCs such as ethyl acetate, glycol ethers, and acetone are organic chemicals that are mainly used as solvents for conventional paints. Once they enter the air we inhale, they can go into our lungs and create a toxic effect on our bodies. The odor emanating from these paints can be quite suffocating.
These chemicals can cause a variety of harmful effects on people who are exposed to it, depending on exposure. These effects can be mild, like minor irritation in the eyes, throat, nose or skin, or could cause a major burning sensation. Since VOCs from these paints can linger in home interiors for a long time, they can cause headaches, nausea and dizziness from regular exposure to the chemicals in conventional paints. Some long-term effects include liver and kidney damage, respiratory issues and even cancer. These paints not only harm the human body, but also the environment. The by-products and waste of the synthetic chemical industry are highly detrimental to the environment and they leave an immense carbon footprint.
The harmful health effects of these toxic paints have made paint companies reconsider the composition of their products. This has led to the development of a new range of non-toxic environmentally friendly paints. They aim to reinvent paints so that serious health and environmental problems can be prevented.
Eco-friendly paints available in India can be classified into three types:
- Zero-VOC paints: The level of VOCs in these paints is so low that they can be termed as ‘zero-VOC paints’. As per the EPA* standard, the total VOC content should be less than 5 grams per liter of paint.
- Low-VOC paints: As specified by the EPA, these paints can have VOC concentrations ranging from 5 to 200 grams per liter of paint.
- Natural paints: These paints are made of natural compounds such as tree resins, water, plant oil, essential oil and natural dyes. They do not contain any VOCs. Water-based paints do not have an odor, while oil-based paints have a smell.
*Since India does not have guidelines on such non-toxic paints, we have considered the standards formulated by the Green Seal Standard for Paints & Coatings and the US Environment Protection Agency (EPA).
It is important to note that most green certifications stand for VOC in the paint base. VOC in colouring agents in the paint, the biggest contributor of VOC, is often ignored. As a thumb rule, darker colours and glossier paints have more VOC. BIS has recently reduced the standard for lead in normal paints from 1,000 ppm to 90 ppm, following the example of the US and China. Paints in India can undergo testing for certification from the National Testing House too, like Nerolac Paints. You can check various eco-friendly acrylic paints available at ubuy india.

Leading brands that sell eco-friendly and non-toxic paints in India:
Asian Paints is India’s largest paint company that provides paint products for personal, industrial and automotive needs. Asian Paints began its journey into non-toxic paints by removing lead and heavy metals from its paints. The company has also substantially reduced the VOC content in its paints to comply with international standards, as specified by the Green Seal Standard for Paints & Coatings. For example, its Ace Exterior Emulsion (White) has 22.22 grams of VOC per liter of paint, which is substantially less than the international standard of 50 grams of VOC.
Berger Paints is another leading paint company that has a broad customer base in India. Through its Green Horizon endeavor, the company seeks to protect the environment by producing better products. Berger Paints has removed lead, mercury and chromium from its paints, which are toxic to the human body. The company has also greatly reduced VOCs (8.4 gram per liter in its Breathe Easy Emulsions) and decreased the content of aromatics so that their products have zero negative health impact. Berger Paints has also diversified into water-based paints, custom-made for the pharmaceutical industry. Their Breathe Easy Emulsions are also water-based.
Dulux is a UK-based multinational company that has several production units in India. The company complies with the highest environmental standards on paints, especially in the area of VOC content. Dulux promotes water-based substitutes actively through its website and other promotional activities. The company offers a wide variety of water-based products such as Paint Mixing Kitchen, Endurance Silk, Magic White Silk, Quick Dry Gloss, Watershield Exterior Satin, and many more.
Nerolac is now the second largest player in the paints market in India. The company had switched to lead-free paints years ago due to the several health hazards associated with lead. All its manufacturing plants are ISO-14001 certified, which helps the company to achieve sound environmental performance. Recently, Kansai Nerolac launched a line of water-based, low-VOC paints that has the National Test House (NTH) certification.
LEINOS, a division of the German company Reincke Naturfarben GmbH, specializes in the production of natural and eco-friendly paints and wood-care products. The key products offered in the Indian market include Terrace Wood Oil 236, Premium Wood Varnish 260, Countertop Oil 280, and Interior Hardwax Oil 290. These products are distinguished by their unique combination of natural ingredients, including linseed oil, beeswax, dammar, carnauba wax, shellac, and clay. This rich composition not only provides a high level of protection but also enhances the durability and aesthetic appeal of treated surfaces. Each ingredient is carefully selected for its natural properties and ability to provide a long-lasting, eco-friendly finish. The products are priced in a range from mid to premium, reflecting their quality and environmental purity. LEINOS products in India can be found through various dealers, with a complete list available on the company website.
It is clear that eco-friendly and non-toxic varieties of paints come at a higher cost than regular paints, but they do last long. They also benefit you and your family’s health, as well as the environment.
The shift to low/zero-VOC paints is seen not only because of an environmentally conscious industry but with an industry that understands that consumers are increasingly buying green-labeled products. Thus, it is necessary that consumers understand what a green label means. Green Seal Certifications (International), EcoMark Scheme (in India) are standards prevalent in the market for green paints. The EcoMark, conferred by the Bureau of Indian Standards (BIS), has the following standards for water-based coatings:
- 5% or less VOC
- Absence of metals like Mercury and its compounds, Lead, Cadmium, Chromium VI and their oxides
- Less than 10 milligrams per kilogram of free formaldehyde
- Absence of chemicals like halogenated solvents, benzene, poly-aromatic hydrocarbons and other aromatic hydrocarbons
