INCI Name and Common References

International Nomenclature of Cosmetic Ingredients name: Polymethylsilsesquioxane Common terms: PMSSQ, silicone resin Nicknames: poly-silicone, polymethylsiloxane, PMSS

Function

Polymethilsilsesquioxane is a silicone-based ingredient that is commonly used in cosmetic formulations as a texturizer, emollient, and film-forming agent. It helps to improve the texture and spreadability of products, while also providing a smooth and silky feel to the skin. Additionally, it can help to enhance the longevity of makeup and other cosmetic products by forming a protective barrier on the skin. Polymethilsilsesquioxane is often used in foundations, primers, and other makeup products, as well as in skincare formulations such as moisturizers and serums.

Science

Polymethylsilsesquioxane is a type of silicone-based polymer that is commonly used in cosmetics and personal care products. Its physical properties include a high surface area, low density, and excellent water repellency. When applied to the skin, polymethylsilsesquioxane forms a thin film that helps to reduce the appearance of fine lines and wrinkles by filling in the gaps between skin cells. It also provides a smooth, silky texture to the skin and helps to improve the spreadability of other ingredients in the formulation. Additionally, its water-repellent properties help to prevent moisture loss from the skin, which can help to keep it hydrated and healthy-looking. Overall, polymethylsilsesquioxane is an effective ingredient in cosmetics and personal care products due to its unique physical properties and ability to improve the appearance and health of the skin.

Benefits

Polymethilsilsesquioxane is a skincare ingredient that can provide a range of benefits to users. Some of the key benefits include its ability to improve skin texture and tone, reduce the appearance of fine lines and wrinkles, and provide a smooth, matte finish to the skin. Additionally, polymethilsilsesquioxane can help to protect the skin from environmental stressors and pollutants, while also providing a lightweight, non-greasy feel. Overall, this ingredient can be a valuable addition to any skincare routine, helping to promote healthy, radiant-looking skin.

Negatives

Polymethylsilsesquioxane is a synthetic ingredient commonly used in cosmetics and personal care products as a thickening agent, emollient, and skin conditioning agent. 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 polymethylsilsesquioxane is skin irritation or allergic reactions. This can occur in individuals who are sensitive to silicone-based ingredients or have a pre-existing skin condition. Symptoms may include redness, itching, swelling, or a rash. If you experience any of these symptoms, discontinue use of the product and consult a healthcare professional. Polymethylsilsesquioxane may also interact with other ingredients in a product, particularly those that are oil-based. This can cause the product to separate or become unstable, which can affect its efficacy and safety. It is important to follow the manufacturer's instructions and avoid mixing products that are not intended to be used together. Additionally, some studies have suggested that polymethylsilsesquioxane may have environmental impacts, particularly when it is washed off and enters waterways. While the long-term effects of this are not yet fully understood, it is important to consider the potential environmental impact of using products containing this ingredient. Overall, while polymethylsilsesquioxane is generally considered safe for use in cosmetics and personal care products, it is important to be aware of potential side effects, sensitivities, and interactions. If you have any concerns or experience any adverse reactions, consult a healthcare professional.

Source

Polymethylsilsesquioxane is a synthetic ingredient that is derived from silica, a natural mineral. The processing pathway involves the hydrolysis of silica to form silicic acid, which is then reacted with methylchlorosilanes to produce polymethylsilsesquioxane. The resulting product is a fine powder that is used in cosmetics and personal care products as a thickening agent and to improve the texture of formulations.

Safety

Polymethylsilsesquioxane has a low safety rating score according to the EWG Skin Deep database. It has been rated as a 1 out of 10, which means it is considered to be a low hazard ingredient. Other sources also suggest that this ingredient is generally safe for use in cosmetics and personal care products. However, as with any ingredient, it is important to use it in moderation and follow the recommended usage guidelines to avoid any potential adverse effects.

Sustainability

Polymethylsilsesquioxane (PMSQ) is a synthetic ingredient commonly used in cosmetics and personal care products as a thickening agent and to improve texture. While there is limited information available on the environmental impact of PMSQ, it is generally considered to be a low-risk ingredient. However, the ethical sourcing of PMSQ may be a concern. The production of PMSQ involves the use of silicones, which are derived from silicon, a non-renewable resource. Additionally, the production of silicones can result in the release of greenhouse gases and other pollutants. To ensure ethical sourcing practices, it is important for companies to work with suppliers who prioritize sustainability and environmental responsibility. This may include sourcing silicones from renewable sources or implementing measures to reduce the environmental impact of production processes. Overall, while the environmental impact of PMSQ may be minimal, it is important for companies to consider the ethical sourcing of this ingredient and work towards more sustainable practices in the cosmetics industry.

Conclusion

In conclusion, polymethylsilsesquioxane is a versatile ingredient commonly used in cosmetics and personal care products due to its ability to improve texture, provide a smooth finish, and enhance the longevity of makeup. While there is limited scientific research on its long-term effects, it is generally considered safe for use in cosmetics. However, its sustainability is questionable as it is a synthetic ingredient derived from non-renewable sources. Overall, while polymethylsilsesquioxane offers benefits in cosmetics, it is important to consider its potential negative impacts on the environment and seek out more sustainable alternatives.
