Aluminum Lactate丨CAS 18917-91-4

Overview

Aluminum lactate丨CAS 18917-91-4 is a white to off-white powder or crystalline solid formed from the reaction of aluminum salts with lactic acid. It is water-soluble, has mild acidity, and possesses both complexing and buffering abilities, making it useful in a range of industrial, cosmetic, and pharmaceutical applications.

Applications

1. Cosmetics and Personal Care

Astringent and Antiperspirant Agent:
Used in deodorants and skincare products due to its ability to tighten pores, reduce sweating, and soothe irritated skin.

Skin Conditioning Agent:
The lactic acid component contributes to moisturization and mild exfoliation, improving skin texture.

pH Regulator:
Helps maintain product stability and skin-friendly pH in lotions, creams, and solutions.

2. Pharmaceutical Uses

Topical Formulations:
Incorporated into dermatological preparations for eczema, dermatitis, and excessive sweating due to its astringent and anti-irritant properties.

Wound Healing Aids:
May be used in wound-care products as an ingredient that supports tissue regeneration and provides a mild antimicrobial effect.

3. Cement, Ceramics, and Building Materials

Dispersing and Setting Agent:
Used in the formulation of special cements, ceramics, and construction materials. Acts as a set retarder or dispersant, particularly in aluminous cement systems.

Binding Agent in Refractories:
Aluminum lactate improves the binding and plasticity of refractory materials, ensuring mechanical strength and durability.

4. Textile and Leather Industry

Tanning Agent:
Functions as a mild tanning and complexing agent for leathers, helping improve durability and softness.

Fixative for Dyes:
Can be used to enhance dye adherence and color fastness on fabrics, especially in eco-conscious or natural dyeing systems.

5. Analytical and Chemical Synthesis

Complexing Agent:
Aluminum lactate can chelate metal ions, making it suitable for analytical chemistry and controlled-release formulations.

Precursor for Aluminum Oxide Materials:
In thermal decomposition processes, it can serve as a source of aluminum oxide (Al₂O₃) for ceramics and catalysts.

Benefits

1. Biocompatibility and Safety

Non-toxic at typical usage levels and well-tolerated on skin, particularly in regulated concentrations in cosmetics and dermatology.

2. Water Solubility

High solubility in water allows for easy formulation in aqueous-based products (lotions, sprays, gels, etc.).

3. Multifunctionality

Provides astringent, buffering, complexing, dispersing, and even film-forming properties, making it useful in diverse sectors from healthcare to industry.

Conclusion

Aluminum lactate丨CAS 18917-91-4 is a versatile and multifunctional compound used in cosmetics, pharmaceuticals, construction, leather processing, and chemical manufacturing. Its ability to act as an astringent, dispersant, and complexing agent, combined with good biocompatibility and water solubility, makes it an ideal additive for both consumer and industrial applications. As demand grows for safe, multifunctional, and sustainable materials, aluminum lactate continues to gain importance in formulation science and material engineering.
