Antioxidants
Butylated hydroxytoluene, often shortened to BHT, is a synthetic chemical compound used in cosmetics as an effective antioxidant. Its structure is based on a toluene molecule, enhanced with hydroxyl and butyl groups, which provide stability. The main function of this substance is to protect products from oxidation, slow down the spoilage processes of fats and oils, and maintain their quality and effectiveness. This ingredient is most often produced in laboratories by chemical synthesis, so it is considered completely artificial and does not belong to naturally derived substances. Despite its effectiveness, the use of BHT is debated due to its potential effects on the skin and the environment, so its concentration in cosmetic products is strictly regulated.
Purpose and Benefits
BHT, or butylated hydroxytoluene, plays a crucial role in cosmetics when it comes to product longevity. This compound ensures that the formula remains stable and effective even long after production. Its antioxidant properties help neutralize free radicals that can cause the breakdown of the product’s structure or active ingredients. This is especially important in skincare products containing sensitive oils or vitamins, such as vitamin E, which quickly oxidizes and loses stability. Without this ingredient, many cosmetic products would lose their effectiveness before even reaching the consumer._x000D_

In hair care products, BHT is also an indispensable ally. It protects ingredients such as plant extracts, fragrances, or natural fats from deterioration. This allows maintaining not only the product’s effectiveness but also its pleasant aroma and texture. This ingredient is especially valued when formulating masks or serums that contain sensitive ingredients requiring additional protection from light and air exposure._x000D_

It should be mentioned that BHT is used in very minimal amounts to avoid potential adverse reactions. Its concentration in cosmetics is carefully controlled, taking into account scientific research and relevant regulations. This allows achieving a balance between product functionality and safety for the user. For this reason, it is often used as an alternative to natural antioxidants, which may not always provide the same level of stability in the long term._x000D_

This substance also has the ability to protect cosmetic products from external factors such as temperature fluctuations or air humidity. Long-term stability guarantee means that the product retains its original properties even under challenging storage conditions. Therefore, the importance of BHT lies not only in protecting the product’s ingredients but also in ensuring its overall reliability every day of use.
Security Information
Used in cosmetics, butylated hydroxytoluene has an interesting safety profile. While this ingredient is generally considered safe when used in low concentrations, some people are known to experience skin irritation or allergic reactions. This can manifest as redness, itching, or rash, especially in sensitive individuals. Regulatory bodies, such as the European Commission, set strict rules and limits to ensure a level of consumer safety. As a result, the concentration of BHT in cosmetic products typically does not exceed 0.1%. Consumers are advised to carefully monitor their skin’s reactions and discontinue use of the product if any adverse symptoms occur. It is important to remember that everyone is unique, so what works for one person may not work for another.
Sustainability and Extraction
The production of butylated hydroxytoluene is primarily based on the petrochemical industry – a process that raises concerns about sustainability and environmental protection. Since this substance is not derived from renewable or natural sources, its production contributes to the use of fossil fuels and the emission of carbon dioxide into the environment. Furthermore, chemical synthesis methods often require a lot of energy and can lead to the formation of secondary waste, the disposal of which is an additional challenge. From a social perspective, BHT production is not closely linked to local communities or fair trade principles, as it does not occur through traditional agricultural or artisanal production channels. For these reasons, this ingredient is not considered a sustainable choice, especially when compared to natural antioxidants, the production of which can be more environmentally friendly and based on renewable resources.
Products
It can be found in various beauty products, especially those containing easily oxidized ingredients. Facial moisturizers rich in vitamins or natural oils often rely on this guarantee of stability. For example, Korean brands like Laneige, COSRX, or Missha use BHT in their popular creams, essences, and serums to maintain the effectiveness of the formulas. This ingredient is also often found in lip balms, where it protects against oxidation and preserves the product’s texture and moisturizing properties for longer. Makeup bases and powders, such as products from Holika Holika or Etude House, also frequently include this stabilizer to ensure long-lasting color and consistency retention. In addition, hair care products, such as serums or oils from Innisfree or The Face Shop, utilize the protection provided by BHT to keep sensitive ingredients effective even after prolonged use.
