Emulsifiers
Steareth-21 is a cosmetic ingredient that is frequently used in various skin care and hair product formulas. It belongs to the stearyl alcohol group, and although its name may sound complicated, its functions are very beneficial. The main task of Steareth-21 is to act as an emulsifier, which helps to combine water with oils, allowing for the creation of smooth, easily spreadable products. In addition, it provides a feeling of softness and hydration to the skin and hair. This ingredient is of synthetic origin, often derived from stearic acid, which is extracted from palm or coconut oils. Its use in cosmetics not only improves texture but also leads to long-lasting comfort when using products. Steareth-21 is an excellent choice for those looking for effective and pleasant cosmetic solutions.
Purpose and Benefits
Steareth-21 is also distinguished by its ability to help stabilize cosmetic product formulas, ensuring their integrity and stability even under challenging conditions. This is particularly important for products such as creams, lotions, or hair care products, where it is essential to maintain their consistency and effectiveness for a long time. In addition, this ingredient allows manufacturers to create a light, non-greasy texture that ideally adapts to the skin or hair surface without leaving a feeling of heaviness. One of the subtle but highly valued benefits of Steareth-21 is its ability to reduce surface tension. This allows products to work more evenly and effectively, ensuring that active ingredients reach the required layers of skin or hair. This function is particularly useful for products designed for intensive hydration, nourishment, or protection. This ingredient is extremely well-tolerated by most skin types, including more sensitive skin. Its gentleness combined with its functionality allows it to be included in a wide range of cosmetic product compositions, from daily care to specialized therapeutic remedies. It is not just a technical element of the formula – it is a true “invisible” helper that contributes to making the use of cosmetics not only effective but also pleasant.
Security Information
When using Steareth-21, it is important to pay attention to its safety aspects. Studies show that this ingredient is well tolerated by most skin types, but in rare cases, allergic reactions may occur, especially in sensitive individuals. For example, some people may experience skin irritation or redness. Regulatory authorities, such as the European Cosmetics Directive, set safety standards according to which the use of Steareth-21 in cosmetics is recognized as safe. Consumers should carefully monitor for potential sensitivity and, if unpleasant symptoms occur, discontinue use of the product and consult a specialist. It is important to follow the recommended usage guidelines to ensure not only an effective but also a safe experience when using cosmetic products.
Sustainability and Extraction
Regarding the ethical and sustainable aspects of Steareth-21 production, it is worth noting that this ingredient is usually of synthetic origin, derived from stearic acid extracted from palm or coconut oils. While palm oil is widely used, its production can have a negative impact on the environment, including deforestation and biodiversity loss. Therefore, it is important for manufacturers to adhere to responsible supply chain management and select only sustainably grown raw materials. Coconut oil, on the other hand, may be somewhat less harmful to the environment, but its combination with palm oil poses challenges related to social conditions, such as improving working conditions and ensuring the rights of local communities. Therefore, transparency and accountability in the supply chain are essential to minimize the negative impact of this ingredient on both the environment and social structures.
Products
Creams, lotions, shampoos, and conditioners are products where this ingredient can often be found. For example, popular Innisfree moisturizers and Etude House hair care products often use Steareth-21 to improve texture and moisturizing properties. It is also found in Missha facial lotions designed for intense skin nourishment. In addition, The Face Shop hair care products also take advantage of the benefits of this ingredient to ensure smoothness and softness. Products of this type are an excellent choice for those looking for effective solutions in their beauty routine.
