Myristyl Lactate, also known as Tetradecyl lactate, is a versatile ingredient commonly found in various cosmetic products. It is primarily sourced from myristyl alcohol and lactic acid, which are both naturally occurring substances. Myristyl alcohol is derived from fatty acids, often sourced from coconut oil or palm kernel oil, while lactic acid is a well-known alpha hydroxy acid (AHA) that can be obtained from fermented carbohydrates.
The use of Myristyl Lactate in cosmetics has a relatively recent history, gaining popularity over the last few decades as the demand for multifunctional and effective skincare ingredients has grown. Its introduction into the cosmetic industry was driven by its ability to provide both skin conditioning and emollient properties, making it a valuable addition to a wide range of products, from moisturizers to makeup.
The production of Myristyl Lactate involves a chemical reaction known as esterification, where myristyl alcohol reacts with lactic acid. This process results in the formation of a stable ester compound that combines the beneficial properties of both parent ingredients. The resulting Myristyl Lactate is a smooth, waxy substance that easily blends into cosmetic formulations, enhancing their texture and performance.
In this section, we will delve into the officially recognized cosmetic benefits and uses of Myristyl Lactate:
Myristyl Lactate is known for its skin conditioning properties. This means it helps to maintain the skin in good condition by improving its appearance and texture. When applied in cosmetic formulations, it can make the skin feel softer and smoother. This is particularly beneficial for those with dry or rough skin, as it can help to restore a more supple and hydrated feel.
As an emollient, Myristyl Lactate plays a crucial role in moisturizing the skin. Emollients work by forming a protective barrier on the skin’s surface, which helps to lock in moisture and prevent water loss. This can be especially useful in products designed for dry or sensitive skin, as it helps to keep the skin hydrated and reduces the likelihood of irritation or flakiness. By maintaining the skin’s moisture balance, Myristyl Lactate helps to keep the skin looking healthy and radiant.
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).
Myristyl Lactate is generally considered safe for topical use in cosmetic products. However, as with any ingredient, there are potential side effects and considerations to keep in mind.
Regarding individuals who are pregnant or breastfeeding, there is a lack of specific data and research on the topical usage of Myristyl Lactate during pregnancy. Therefore, it is advisable for these individuals to consult a healthcare professional for further advice.
Adverse reactions to Myristyl Lactate are relatively uncommon, but they can occur. To minimize the risk of an adverse reaction, it is recommended to conduct a patch test before widespread usage.
Myristyl Lactate has a comedogenic rating of 2, which means it has a low to moderate likelihood of clogging pores. Individuals who are prone to acne, blemishes, or breakouts should be aware of this rating when considering products containing this ingredient.
