Mea-Thiolactate, also known as Propanoic acid, 2-mercapto-, compound with 2-aminoethanol (1:1), is a chemical compound primarily used in the cosmetic industry for hair waving or straightening. This ingredient is a combination of 2-mercaptopropanoic acid and 2-aminoethanol in a 1:1 ratio. The mercapto group (–SH) in its structure is crucial for breaking the disulfide bonds in hair, which allows for the reshaping of hair strands, making it an effective agent for both curling and straightening treatments.
The history of Mea-Thiolactate in cosmetics dates back to the mid-20th century when the beauty industry was exploring various chemicals to achieve longer-lasting hair styling results. As the demand for more effective and less damaging hair treatments grew, Mea-Thiolactate emerged as a viable option due to its ability to alter hair structure without causing excessive damage.
The production of Mea-Thiolactate involves a chemical reaction between 2-mercaptopropanoic acid and 2-aminoethanol. This process typically occurs in a controlled laboratory setting to ensure the correct stoichiometric balance and purity of the final product. The resulting compound is then incorporated into various hair care formulations designed for professional and at-home use, providing consumers with the ability to achieve their desired hair texture and style.
In this section, we will delve into the officially recognized cosmetic benefits and uses of Mea-Thiolactate:
Mea-Thiolactate is a key ingredient in products designed for hair waving. This means it helps to create waves in the hair, giving it a more voluminous and textured appearance. The compound works by breaking and reforming the disulfide bonds in the hair’s keratin structure, allowing the hair to be reshaped into waves. This is particularly beneficial for individuals looking to add natural-looking waves to their hair without the use of heat styling tools.
In addition to its waving capabilities, Mea-Thiolactate is also used in hair straightening products. Similar to its waving function, it breaks the disulfide bonds in the hair, but instead of creating waves, it allows the hair to be straightened. This can be a game-changer for those with curly or wavy hair who desire a sleek, straight look. The ingredient helps to achieve long-lasting straightness, reducing the need for frequent heat styling, which can be damaging to the hair.
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).
Mea-Thiolactate, while effective for hair waving or straightening, does come with potential side effects and considerations that users should be aware of. Its safety profile is generally well-documented, but like any cosmetic ingredient, it may not be suitable for everyone.
Regarding individuals who are pregnant or breastfeeding, data and research on the topical usage of Mea-Thiolactate during pregnancy are lacking. Therefore, it is advisable for these individuals to consult a healthcare professional for further advice before using products containing this ingredient.
Adverse reactions to Mea-Thiolactate 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.
In terms of comedogenicity, Mea-Thiolactate scores a 1 on a scale of 0 to 5, where 0 is totally non-comedogenic and 5 is highly comedogenic. This low score indicates that it is unlikely to clog pores, making it a suitable option for individuals prone to acne, blemishes, or breakouts.
