Palm oil is a widely used ingredient in soap making due to its ability to create firm bars with a creamy lather. However, its popularity has been overshadowed by significant environmental and social concerns.
The production of palm oil is linked to deforestation, habitat destruction, greenhouse gas emissions, and unethical labor practices. This article explores the reasons why palm oil should not be used in soap, focusing on its environmental impact, social implications, and alternatives available for soap makers.
Environmental Impact of Palm Oil
Deforestation and Habitat Loss
The expansion of palm oil plantations is a major driver of deforestation, particularly in tropical regions like Indonesia and Malaysia. These forests are not only rich in biodiversity but also serve as critical carbon sinks. The clearance of forests for palm oil cultivation leads to the loss of valuable ecosystems and the destruction of wildlife habitats.
According to the World Wildlife Fund (WWF), large areas of tropical forests have been cleared to make room for vast monoculture palm oil plantations, threatening endangered species such as rhinos, elephants, and tigers.
Greenhouse Gas Emissions and Pollution
The process of establishing palm oil plantations often involves burning forests and peatlands, releasing massive amounts of carbon dioxide and other greenhouse gases into the atmosphere.
This contributes significantly to climate change and air pollution. Additionally, palm oil production relies heavily on fertilizers and pesticides, which can lead to water pollution and soil degradation.
Water Pollution
Palm oil plantations contribute to water pollution through agricultural runoff and industrial waste. The effluent from palm oil mills can cause severe freshwater pollution, affecting downstream biodiversity and local communities. The use of fertilizers in these plantations increases surface runoff, leading to nutrient pollution in waterways, which can cause algae blooms and "dead zones" where marine life cannot survive.
Social Implications of Palm Oil Production
Labor Practices
The palm oil industry is plagued by unethical labor practices, including the use of cheap labor and child labor. This keeps the cost of palm oil low but exploits workers, particularly in Indonesia and Malaysia, where most of the world's palm oil is produced. Reports have also highlighted issues of sexual harassment and lack of freedom of association among workers on palm oil plantations.
Community Displacement
The expansion of palm oil plantations often results in the displacement of local communities. Traditional lands are converted into plantations, leading to conflicts over land rights and cultural heritage. This not only affects the livelihoods of these communities but also erodes their cultural identity.
Alternatives to Palm Oil in Soap Making
Babassu Oil
One of the closest substitutes for palm oil in soap making is babassu oil. It offers similar firming and moisturizing properties, with a lighter feel on the skin. Babassu oil can be used to replace some or all of the palm oil in a recipe, though adjustments may be needed in the lye calculation.
Tallow and Lard
Tallow and lard are also viable alternatives, providing hardening properties similar to palm oil. They can be used in place of palm oil to create firm bars of soap.
Coconut Oil and Other Oils
Increasing the amount of coconut oil in a soap recipe can help achieve hardness, though it may require additional moisturizing oils to prevent dryness. Other oils like avocado, sweet almond, and jojoba can add moisturizing properties while helping to create a creamy lather.

Hard Butters
Adding hard butters such as mango, cocoa, and shea butter can enhance the hardness of soap bars while providing moisturizing benefits.
The Final Word
While palm oil offers beneficial properties for soap making, its environmental and social costs are significant. The use of palm oil contributes to deforestation, greenhouse gas emissions, water pollution, and unethical labor practices. Instead of boycotting palm oil entirely, which could lead to increased demand for less efficient alternatives, supporting sustainable palm oil practices through certifications like RSPO can help mitigate these issues.
However, for those committed to avoiding palm oil, there are viable alternatives available that can achieve similar soap-making results without the environmental and social drawbacks. Ultimately, the choice to use or avoid palm oil in soap making should be informed by a consideration of these broader impacts.
