What is α-Hydroxy Acid Lotion?

Hydroxy acids are derivatives of carboxylic acids in which a hydrogen atom on the hydrocarbon group is replaced by a hydroxyl group. This substitution can occur in fatty acids to form alkyds or in aromatic acid molecules to form phenolic acids. When naming hydroxy acids, their origin is often considered. In systematic nomenclature, the longest carbon chain containing both carboxyl and hydroxyl groups is selected as the main chain and numbered accordingly, starting from the carboxyl group closest to the hydroxyl group.

Hydroxy acids are typically found in the form of crystals or syrupy liquids. They have higher melting points compared to fatty acids with the same number of carbon atoms, and they exhibit high water solubility. The chemical properties of hydroxy acids are similar to those of carboxylic acids, but they also possess unique characteristics due to the presence of hydroxyl groups. The position of the hydroxyl group relative to the carboxyl group influences the properties of the hydroxy acid. For instance, an α-hydroxyl group significantly increases the acidity of the carboxylic acid, while a β-hydroxyl group has minimal impact on acidity.

When heated together with a dilute acid, α-hydroxy acids can decompose to produce an aldehyde (or ketone) and formic acid. They can also be oxidized to carboxylic acids by weak oxidants such as Tollen’s reagent. Under the presence of dehydrating agents, intermolecular dehydration can occur leading to the formation of cyclic esters or lactides. Beta-hydroxy acids can undergo heating to form α,β-unsaturated acids. Likewise, when γ- or δ-hydroxy acids are heated, intramolecular water loss can result in the formation of cyclic esters known as lactones.

Phenolic acids, on the other hand, exhibit properties typical of both aromatic acids and phenols.

Application of α-Hydroxy Acid Lotion

Alpha-hydroxy acids, commonly known as AHAs, are organic acids with a hydroxyl group at the alpha position. They are naturally found in fruits and plants such as apples, lemons, and sugar cane, which is why they are also referred to as fruit acids. AHAs are widely used in the food and pharmaceutical industries due to their moisturizing and exfoliating properties.

AHAs are small molecules that can be easily absorbed by the skin, providing excellent moisturization. They also have exfoliating properties that help in removing dead skin cells, improving skin texture, reducing fine lines, and evening out skin tone. This makes them a popular ingredient in cosmetics, where they are added to enhance the effectiveness of skincare products.

Common AHAs used in cosmetics include lactic acid, glycolic acid, citric acid, malic acid, and tartaric acid. These acids are often derived from fruit or plant extracts like lemon, blueberry, orange, sugar cane, papaya, and grape seed. In addition, lactic acid fermentation liquid is also a popular ingredient in skincare products.

Glycolic acid and lactic acid are the most commonly used AHAs in cosmetics, with glycolic acid being known for its ability to penetrate the skin effectively and promote cell turnover. Lactic acid, on the other hand, acts as a natural moisturizing factor in the skin, providing hydration with less irritation. These AHAs are added to cosmetics in varying concentrations based on the desired effects.

In conclusion, AHAs are versatile ingredients in cosmetics that offer multiple benefits for the skin. They are widely used for their moisturizing, exfoliating, and anti-aging properties, making them popular choices for skincare formulations.


α-Hydroxy Acid Lotion Preparation

The method of preparing α-Hydroxy Acid Lotion involves adding catalyst and liquid reaction materials consisting of solvent, hydrogen peroxide aqueous solution, and cycloalkane or its derivatives to the reaction section of a catalytic distillation tower. The mixture flows through the tower, where the liquid reaction material undergoes a catalytic oxidation reaction. The solvent is separated from the vaporized reaction material for recycling, while the catalyst and unvaporized material are separated and recycled. Unreacted naphthenes or derivatives are also separated for recycling. The catalyst used is titanium silicon molecular sieve or modified titanium silicon molecular sieve with a particle size range of 0.2~800μm. The reaction temperature is below the boiling point of the product, at a pressure of 0.1~2.0MPa. The catalyst to cycloalkane ratio is 1:5~100, with a liquid reaction material mass space velocity of 0.01~10h-1 and a top material reflux ratio of 1~30:1. The molar ratio of naphthenes or derivatives to solvent is 1:1.5~30, while the molar ratio of hydrogen peroxide is 0.1~10:1.

α-Hydroxy Acid Lotion Purification

A process for purifying alpha-hydroxy acids on an industrial scale (i.e. producing at least 1000 tons per year), the process includes:

(a) Treating the aqueous solution containing predominantly alpha-hydroxy acid through an extraction step to generate an aqueous phase rich in alpha-hydroxy acid. The chiral purity of the monomeric hydroxy acids in the aqueous solution containing mainly alpha-hydroxy acids is preferably over 90%, and ideally over 95%.

(b) Concentrating the aqueous phase containing alpha-hydroxy acid by evaporating water at reduced pressure to produce a concentrated solution of alpha-hydroxy acid in water. This concentrated solution should have a total acid content of at least 70% by weight, based on the total feed stream, and a monomeric alpha-hydroxy acid content of at least 70% by weight. Additionally, if relevant, the enantiomeric ratio of the alpha-hydroxy acid is not equal to 1.

(c) Crystallizing the concentrated solution of alpha-hydroxy acid to obtain pure alpha-hydroxy acid. The crystallization process may involve: (i) directly cooling the concentrated solution in a melt crystallization device, and/or (ii) diluting the concentrated solution with water and completing crystallization in one or more cooling or evaporative crystallization units, and/or (iii) conducting crystallization in one or more adiabatic crystallization units.
