Market & IP Analysis of Eco-Friendly Paints

Market & IP Analysis of Eco-Friendly Paints – A Step Closer To A Non-Toxic Home

Have you ever experienced a distinct odour when entering a freshly painted room? That characteristic smell is most likely the result of toxic paint fumes that linger on for days and at times, even weeks or years. A majority of conventional paints contain toxic fumes such as Volatile Organic Compounds (VOCs) ­­­- exposure to which pose health and environmental risks, especially when used indoors. This is particularly alarming since studies have found that indoor VOC levels are routinely ten times higher than outdoor levels and are up to a thousand times higher right after painting. These harmful VOCs get dispersed into the air at high levels after the paint dries and may have both short and long-term adverse health effects.

Although VOC levels are the most extreme during and after painting, they continue to get released from painted walls for several years. In fact, only half of the initial VOCs may be released in the first year. This prolonged release of toxic contaminants has led to the emergence of eco-friendly paints that are made up of natural materials.

Natural paints or eco-friendly paints are specifically designed to have zero or lower levels of VOCs. As a result, such paints improve the interior air quality, are beneficial to the environment, and eliminate the discomfort caused by the harmful chemicals present in traditional chemical paints. This article discusses the need for eco-friendly paints, its types, benefits, market penetration, challenges, and IP analysis.

The Severe Impact of Conventional Paints on Human Health & Environment

1. Effect on Human Health

Traditional chemical-based paints contribute to volatile pollutants and reduce indoor air quality. Moreover, as per the Environmental Protection Agency, VOCs may have adverse effects on health which may be caused by short-term and longer-term exposure to VOCs. Unless and until people use products containing safe ingredients, they can expose themselves and their loved ones to very high pollutant levels, and elevated concentrations can persist in the air long after whitewashing is completed.

These chemicals can cause various adverse effects on people (Shown in Figure 1), depending on the exposure time.

Figure 1: Adverse Effects of VOCs on Human Health

2. Effect on Environment

Apart from the adverse impact on human health, traditional paints are also harmful to the environment. Consider this fact, conventional paints are a product of the non-sustainable petrochemical industry, and their production can generate a massive quantity of toxic waste. The toxic waste may contain metals such as lead, chromium, silver, cadmium, mercury, barium, arsenic and selenium. These metals cause severe ecological degradation, including a lasting impact on aquatic life, underground water, and soil.

Therefore, the health and environmental safety concerns while selecting high VOC paints are critical. An eco-friendly paint or natural paint helps in eliminating such risk.

Once you realize the need for eco-friendly paints, it is natural to understand the types of eco-friendly paints available in the market.

Are All Eco-Friendly Paints the Same?

To be eco-friendly, a paint must not contain chemicals such as formaldehyde, phthalates, isoaliphates, 1, 3 butadiene, bisphenol A, toluene and toluene compounds, crystalline quartz silica, alkyl phenolic compounds, heavy metals or biocides, etc. Eco-friendly paints do not contain toxic chemicals, and in case it does contain any VOC, it is in the lowest possible amount that does not pose severe health or environmental impact.

Eco-friendly paints can be classified into three types, as shown in Figure 2 below.

Figure 2: Types of Eco-Friendly Paints   

1. Natural Paints: These paints are made of natural compounds such as tree resins, water, plant oil, milk casein, natural latex, bees wax, plant, earth, mineral dyes, essential oils, and natural minerals. They do not contain any VOCs. Water-based paints are odour-free, while oil-based paints have a smell.

2. Zero VOC Paints: The level of VOCs in these paints is relatively low so that they can be termed as ‘zero-VOC paints.’ Such paints contain a minimal VOC percentage, i.e., less than five g/litre of VOC.

3. Low VOC Paints: These paints contain five g/litre to 50 g/litre of VOC. In addition, they use water as a solvent.

The positives of using eco-friendly paints are enormous irrespective of their type. The following section will discuss the advantages of using eco-friendly paints.

Benefits of Eco-Friendly Paints

Since eco-friendly paints are low in VOCs, they’re much safer to use in homes, hospitals, or schools. Additionally, there are set specific standards, such as the one mentioned here, that paints must meet to qualify as ‘eco-friendly’.

With advanced manufacturing techniques, eco-friendly paints are durable and greener than the conventional options. These paints are designed in a large selection of hues to supplement any style while offering better performance, improving the overall atmosphere of your household, and safeguarding the environment.

Eco-friendly paint also offers a variety of other benefits, as shown in Figure 3 below:

Figure 3: Benefits of Eco-Friendly Paints

1. Low VOC Content: As discussed initially, VOCs are present in most commercial chemical paints. These VOCs not only leave behind a characteristic odour and floating pollutants that affect indoor atmosphere, but are also non-biodegradable and non-recyclable. On the other hand, eco-friendly paints have no or low VOCs, producing much less waste and damage.

2. Cost-Effective Options: Superficially, environment-friendly paints may seem more expensive than traditional paints. However, along with their eco-friendly benefit, these paints may also feature superior quality than chemical-based products, justifying the associated cost. Besides, they have better color retention, improved coverage, viscosity, abrasion resistance, paint coverage, and rare chances of yellowing.

3. Natural Raw Materials: Eco-friendly paints are manufactured only from natural ingredients such as lemon peel extract, seed oil, bees wax, milk protein, etc. These natural raw materials do not produce harmful emissions and adverse effects on the environment during manufacturing and upon product application.

4. Minimal Environmental Impact: Eco-friendly paints help reduce carbon footprint and are biodegradable since they utilize water or alternative environment-friendly materials as a base. The use of water or other eco-friendly material as a solvent cuts the risk of harmful VOCs emission that is generated from the conventional paints containing harmful chemicals such as: Bisphenol A (BPA), N-methyl pyrrolidone (NMP) solvent, Isothiazolinone preservatives, and Nonyl phenol-based surfactants.

5. Healthier Alternative: The VOCs found in chemical paints are active up to five years after the initial application. Hence, individuals continuously exposed to VOCs are at a higher risk of developing respiratory illness, sensitivity, and lung cancer. On the other hand, eco-friendly paints manufactured from natural and environment-friendly ingredients are entirely safe for humans and the environment.

6. Superior Coverage: Besides reducing the impact of harmful emissions on the environment, eco-friendly paints are also qualitatively better than their chemical counterparts. Eco-friendly paints will give your walls superior coverage, improved colour retention capacity, viscosity, offer wide range of colors, minimal abrasion, and avoid issues such as yellowing of paint.

7. Reduced wastage: While analyzing the reduced waste production, eco-friendly paints are far better than conventional chemical-based paints. Chemical paints emit toxic VOCs when manufactured and even years after their application. But, natural ones are without any such by-products.

Despite its many benefits, consumers are still lagging in making the transition towards eco-friendly paints. A common misconception among consumers is that they will be compromising on quality and finishing upon switching to eco-friendly paints. However, in reality, the fact remains that eco-friendly paints offer a wide range of color palette, are durable, and are long lasting. So, consumers do not have to strike a balance with the elegance while choosing eco-friendly paints. Although eco-friendly paints are relatively costlier than conventional paints, the range of benefits offered is worth every penny spent.

So, is there a trade-off between eco-friendliness and aesthetics?

The benefits that low VOC paint offers makes it attractive for the buyers, provided they know how to identify a low-VOC or a no-VOC paint.

How to Spot a Low-VOC or No-VOC Paint?

There are three ways to spot a low-VOC or no-VOC paint, as shown in Figure 4 below:

Figure 4: Three Ways to Spot a Low-VOC or No-VOC Paint

1. 50 g/L or Below: VOC levels are generally expressed in grams per litre (g/l) or pounds per gallon (lbs/gal). Most low VOC paints sold by reputed brands contain levels of 50 g/L or below. However, the numbers mentioned on the paint container are the measurements that are taken before pigment or any additives are added.

2. The Green Seal: Paints containing the green seal are guaranteed to fulfil high environmental standards and performance requirements. Paints with a green seal also confirm that they meet the requisite compliance and are free from a wide range of toxic chemicals including, reproductive toxins, carcinogens, heavy metals, hazardous air pollutants, and formaldehyde-donors.

3. Natural Paints: These paints use naturally occurring materials, such as, lime, clay, linseed oil, and chalk. Natural paints do not utilize any synthetic oil products. As a result, they naturally contain low VOCs with regulation by the Environmental Protection Agency (EPA) for air quality. Buyers should always check the composition on the label since some natural paints may contain unchecked VOCs.

Having stated how to pick out low-VOC or no-VOC paint, let us now discuss the present and future market penetration of low VOC paint.
