Magnesium Laureth-11 Carboxylate: An In-Depth Look at Its Role in Cosmetics

What Is Magnesium Laureth-11 Carboxylate?

Magnesium Laureth-11 Carboxylate, also known by its chemical name Poly(oxy-1,2-ethanediyl), .alpha.-carboxymethyl-.omega.-dodecyloxy-, magnesium salts (10 mol EO average molar ratio), is a synthetic compound primarily used in cosmetic products for its cleansing properties. This ingredient is derived from lauryl alcohol, which is a fatty alcohol obtained from natural sources such as coconut oil or palm kernel oil. The “11” in its name refers to the average number of ethylene oxide units in its structure, which contributes to its surfactant properties.

The history of Magnesium Laureth-11 Carboxylate in cosmetics dates back to the mid-20th century when the demand for more effective and mild cleansing agents began to rise. Researchers were exploring various ways to enhance the performance of surfactants, leading to the development of ethoxylated compounds like Magnesium Laureth-11 Carboxylate. Its ability to effectively remove dirt and oil without being overly harsh on the skin made it a popular choice in formulations.

The production of Magnesium Laureth-11 Carboxylate involves a multi-step chemical process. Initially, lauryl alcohol undergoes ethoxylation, where ethylene oxide is added to the alcohol to form laureth-11. This intermediate product is then carboxymethylated, introducing a carboxyl group into the molecule. Finally, the compound is neutralized with magnesium salts to form Magnesium Laureth-11 Carboxylate. This process results in a surfactant that is both effective and relatively mild, making it suitable for use in a variety of personal care products.

The Benefits/Uses of Magnesium Laureth-11 Carboxylate

In this section, we will delve into the officially recognized cosmetic benefits and uses of Magnesium Laureth-11 Carboxylate:

Cleansing

Magnesium Laureth-11 Carboxylate is primarily used for its cleansing properties. This means it helps to remove dirt, oil, and other impurities from the skin and hair. When included in products like shampoos, facial cleansers, and body washes, it aids in creating a lather that effectively lifts away grime, leaving the skin and hair feeling fresh and clean. This is particularly beneficial for those looking to maintain a clear complexion or healthy scalp by ensuring that residues and pollutants are thoroughly washed away.

Note: The listed benefits above are exclusively based on the officially recognized and defined functions of the ingredient, as documented by the International Nomenclature of Cosmetic Ingredients (INCI).

Potential Side Effects & Other Considerations

Magnesium Laureth-11 Carboxylate is generally considered safe for use in cosmetic products. However, as with any ingredient, there are potential side effects and considerations to keep in mind.

• Skin irritation: Some individuals may experience mild irritation, especially if they have sensitive skin.
• Allergic reactions: Although rare, allergic reactions such as redness, itching, or swelling can occur.
• Dryness: Prolonged use may lead to dryness in some skin types.

Regarding individuals who are pregnant or breastfeeding, data and research on the topical usage of Magnesium Laureth-11 Carboxylate during pregnancy are lacking. Therefore, it is recommended that they consult a healthcare professional for further advice.

Adverse reactions to Magnesium Laureth-11 Carboxylate are uncommon. However, it is always a good idea to conduct a patch test before widespread usage to ensure there are no adverse reactions.

In terms of comedogenicity, Magnesium Laureth-11 Carboxylate has a rating of 1 on a scale of 0 to 5, where 0 is totally non-comedogenic and 5 is highly comedogenic. This low rating indicates that it is unlikely to clog pores, making it suitable for individuals prone to acne, blemishes, or breakouts.
