INCI Name and Common References

International Nomenclature of Cosmetic Ingredients name: PEG-150 Distearate Common terms: Polyethylene glycol 150 distearate Nicknames: PEG-150 DS, PEG-150 Stearate

Function

PEG-150 Distearate is an emulsifying agent that is commonly used in cosmetic formulations. It helps to mix oil and water-based ingredients together, creating a smooth and consistent texture. This ingredient also acts as a thickener, giving the product a more luxurious feel. Additionally, PEG-150 Distearate can help to improve the stability and shelf life of the product.

Science

PEG-150 Distearate is a type of polyethylene glycol that is derived from stearic acid. It is commonly used in cosmetic and personal care products as an emulsifier, which means it helps to mix oil and water-based ingredients together. This is due to its physical properties, which include a high molecular weight and a hydrophilic (water-loving) nature. When added to a formulation, PEG-150 Distearate forms a stable emulsion by surrounding oil droplets with a layer of hydrophilic molecules, preventing them from clumping together and separating from the water-based components. This allows for a smooth and consistent texture in the final product. Additionally, PEG-150 Distearate can also act as a surfactant, reducing the surface tension between different ingredients and improving their spreadability and absorption into the skin.

Benefits

PEG-150 Distearate is a versatile ingredient that offers several skincare benefits. It is a mild surfactant that helps to cleanse the skin without stripping it of its natural oils. It also acts as a thickening agent, giving skincare products a luxurious texture. PEG-150 Distearate is known for its moisturizing properties, helping to hydrate and soothe dry, irritated skin. Additionally, it can improve the absorption of other active ingredients in skincare products, making them more effective. Overall, PEG-150 Distearate is a beneficial ingredient for those looking to improve the texture and hydration of their skin.

Negatives

PEG-150 Distearate is a common ingredient in many personal care and cosmetic products, including shampoos, conditioners, and body washes. While it is generally considered safe for use, there are some potential side effects, sensitivities, and interactions that should be taken into consideration. One possible side effect of PEG-150 Distearate is skin irritation. This can occur in individuals who are sensitive to the ingredient or who have pre-existing skin conditions. Symptoms of skin irritation may include redness, itching, and rash. Another potential sensitivity to PEG-150 Distearate is eye irritation. If the ingredient comes into contact with the eyes, it can cause redness, burning, and tearing. It is important to avoid getting the product in the eyes and to rinse thoroughly with water if contact does occur. In addition, PEG-150 Distearate may interact with other ingredients in a product. For example, it may reduce the effectiveness of certain preservatives or antimicrobial agents. This can lead to an increased risk of bacterial or fungal growth in the product. Overall, PEG-150 Distearate is a safe and effective ingredient when used as directed. However, individuals with sensitive skin or eyes should be cautious when using products containing this ingredient. It is also important to be aware of potential interactions with other ingredients in a product to ensure its safety and effectiveness.

Source

PEG-150 Distearate is a synthetic ingredient that is derived from polyethylene glycol and stearic acid. It is commonly used as an emulsifier and thickening agent in cosmetic and personal care products. The processing pathway involves the reaction of stearic acid with ethylene oxide to form polyethylene glycol stearate, which is then further reacted with additional ethylene oxide to produce PEG-150 Distearate.

Safety

According to the EWG Skin Deep database, PEG-150 Distearate has a safety rating of 3 out of 10, which indicates a moderate level of concern. This ingredient has been flagged for potential skin irritation and toxicity concerns. Other sources also suggest that PEG-150 Distearate may be harmful to the environment and aquatic life. Overall, it is important to use caution when using products containing this ingredient and to consider alternative options if possible.

Sustainability

PEG-150 Distearate is a synthetic ingredient commonly used in personal care products such as shampoos, conditioners, and body washes. While it is generally considered safe for use in cosmetics, its environmental impact and ethical sourcing practices are a cause for concern. PEG-150 Distearate is derived from petroleum, a non-renewable resource that contributes to greenhouse gas emissions and climate change. The production of petroleum also involves drilling, which can have negative impacts on local ecosystems and communities. In addition, the manufacturing process of PEG-150 Distearate involves the use of ethylene oxide, a toxic chemical that can be harmful to human health and the environment. Ethylene oxide is a known carcinogen and can also cause respiratory problems and skin irritation. As for ethical sourcing practices, there is little information available on the sourcing of PEG-150 Distearate. However, given that it is derived from petroleum, it is likely that its production involves the exploitation of natural resources and potentially harmful working conditions for those involved in the extraction and processing of petroleum. Overall, while PEG-150 Distearate may be a common ingredient in personal care products, its environmental impact and ethical sourcing practices are concerning. Consumers should consider choosing products that use more sustainable and ethically sourced ingredients.

Conclusion

In conclusion, PEG-150 Distearate is a versatile ingredient commonly used in personal care products due to its emulsifying and thickening properties. While it is generally considered safe for use, there are some concerns about its potential to cause skin irritation and environmental impact. It can be derived from both natural and synthetic sources, and its sustainability depends on the source and production methods used. Overall, PEG-150 Distearate can provide benefits to personal care products, but it is important to consider its potential negatives and sustainability when choosing products containing this ingredient.
