Sodium Aluminum Lactate, also known by its chemical composition as aluminum, lactate sodium complexes, basic, is a compound that has found its niche in the world of cosmetics. This ingredient is primarily sourced from the combination of sodium lactate and aluminum salts. Sodium lactate itself is derived from the fermentation of sugars, typically from corn or beets, while aluminum salts are commonly obtained from naturally occurring minerals.
The use of Sodium Aluminum Lactate in cosmetics is relatively modern, emerging as formulators sought multifunctional ingredients that could enhance product stability and efficacy. Historically, both sodium lactate and aluminum compounds have been utilized separately for various purposes, including food preservation and medicinal applications. Their combination into Sodium Aluminum Lactate leverages the beneficial properties of both components, making it a valuable addition to cosmetic formulations.
The production of Sodium Aluminum Lactate involves a controlled chemical reaction where sodium lactate is reacted with aluminum salts under specific conditions to form a stable complex. This process ensures that the resulting compound maintains the desired properties of astringency and buffering, which are crucial for its role in skincare and other cosmetic products.
In this section, we will delve into the officially recognized cosmetic benefits and uses of Sodium Aluminum Lactate:
Sodium Aluminum Lactate acts as an astringent, which means it helps to tighten the skin and reduce the appearance of pores. This can be particularly beneficial for individuals with oily or acne-prone skin, as it helps to control excess oil and minimize the likelihood of breakouts. By tightening the skin, it can also give a smoother and more refined appearance, making it a popular choice in toners and facial cleansers.
Another key function of Sodium Aluminum Lactate is its role as a buffering agent. This means it helps to maintain the pH balance of cosmetic products, ensuring they remain effective and safe for use. A stable pH is crucial for the skin’s health, as it helps to protect against harmful bacteria and environmental stressors. By keeping the product’s pH in check, Sodium Aluminum Lactate ensures that the formulation remains gentle on the skin while still delivering its intended benefits.
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).
When considering the use of Sodium Aluminum Lactate in cosmetic products, it is important to be aware of its safety, suitability, and allergenic potential. While generally regarded as safe for topical application, there are some potential side effects to be mindful of:
Regarding individuals who are pregnant or breastfeeding, data and research on the topical usage of Sodium Aluminum Lactate during pregnancy are lacking. Therefore, it is advisable for pregnant or breastfeeding women to consult a healthcare professional for further advice before using products containing this ingredient.
Adverse reactions to Sodium Aluminum Lactate are relatively uncommon, but as with any cosmetic ingredient, individual responses can vary. To minimize the risk of adverse reactions, it is recommended to conduct a patch test before widespread usage.
In terms of comedogenicity, Sodium Aluminum Lactate has a rating of 1 on a scale of 0 (totally non-comedogenic) to 5 (highly comedogenic). This low rating suggests that it is unlikely to clog pores and is generally suitable for people prone to acne, blemishes, or breakouts.
