Toxicity	Highly toxic if ingested	Contains denaturants to make it toxic if ingested
Color	Clear	Usually colored (e.g., purple or blue)

Introduction

When it comes to cleaning and disinfecting, two common options are 99.9% pure ethanol and methylated spirits. Both substances have their own unique attributes that make them suitable for different purposes. In this article, we will compare the characteristics of these two products to help you determine which one is best for your needs.

Chemical Composition

99.9% pure ethanol, also known as absolute ethanol, is a type of alcohol that is free from impurities. It is made through a process of distillation that removes water and other contaminants, resulting in a highly pure form of ethanol. On the other hand, methylated spirits, also known as denatured alcohol, is ethanol that has been mixed with additives such as methanol or isopropanol to make it toxic and undrinkable. This makes methylated spirits unsuitable for consumption but suitable for industrial and household use.

Uses

99.9% pure ethanol is commonly used in laboratories and pharmaceutical industries for purposes such as sterilization, extraction, and as a solvent for chemicals. It is also used in the production of alcoholic beverages and as a fuel for alcohol burners. Methylated spirits, on the other hand, is often used as a solvent for cleaning and degreasing surfaces, as well as for fueling camping stoves and lamps. It is also used in the production of paints and varnishes.

Flammability

Both 99.9% pure ethanol and methylated spirits are highly flammable substances. Due to their alcohol content, they can easily catch fire when exposed to a flame or spark. It is important to handle these substances with care and store them in a safe place away from sources of ignition. When using them for cleaning or fueling purposes, it is essential to follow proper safety precautions to prevent accidents.

Toxicity

While 99.9% pure ethanol is safe for consumption in small quantities, methylated spirits are toxic and should never be ingested. The additives in methylated spirits make it harmful to humans and animals if consumed, leading to serious health consequences. When using methylated spirits for cleaning or other purposes, it is important to wear protective gear such as gloves and goggles to prevent skin contact and inhalation of fumes.

Cost

In terms of cost, methylated spirits are generally more affordable than 99.9% pure ethanol. This is due to the fact that methylated spirits are a mixture of ethanol and additives, which makes them cheaper to produce. For budget-conscious consumers, methylated spirits may be a more cost-effective option for cleaning and other household tasks. However, for industries that require high-purity ethanol for specific applications, the higher cost of 99.9% pure ethanol may be justified.

Conclusion

In conclusion, both 99.9% pure ethanol and methylated spirits have their own unique attributes that make them suitable for different purposes. While 99.9% pure ethanol is highly pure and suitable for laboratory and pharmaceutical use, methylated spirits are more affordable and commonly used for cleaning and fueling purposes. When choosing between these two substances, it is important to consider factors such as flammability, toxicity, cost, and intended use to determine which one is best for your needs.
