Lactobionic Acid

Lactobionic acid combines multiple hydroxyl groups with a carboxylic acid group. This structure supports its use as a humectant and chelating ingredient in aqueous formulations. Its INCI name is Lactobionic Acid.

Key Features

• Supports hydration in creams, lotions and serums.

• Provides a PHA option for exfoliating formulations.

• Binds metal ions, supporting formulation stability where trace metals are a concern.

• Dissolves in water for incorporation into aqueous systems.

Typical Specifications

Confirm the current specification, assay method and reporting basis before ordering. Commercial lactobionic acid can contain both acid and lactone forms, so assay results should be interpreted using the stated test method.

Applications of Lactobionic Acid

Cosmetics and Personal Care

• Hydrating skincare: Used in facial serums, moisturizers and body-care products.

• Exfoliating formulations: Offers an alternative to conventional AHAs when developing products for smoother-looking skin.

• Formula development: Provides chelating functionality alongside its skincare role.

Performance and tolerance depend on concentration, final pH and the complete formulation. A mild ingredient profile does not guarantee that every finished product will suit sensitive skin.

Pharmaceutical Formulation

• Organ preservation: Lactobionic acid/lactobionate is a component of certain formulated organ storage solutions.

• Salt preparation: Used in developing lactobionate salts for specific pharmaceutical applications.

These uses require appropriate material qualification and control of relevant impurities. The powder described here should not be assumed to be sterile or suitable for injectable manufacture.

Biotechnology and Research

• Bioconjugation: Investigated as a galactose-bearing molecule for attachment to polymers and nanoparticles.

• Biomaterial development: Used in research on surface modification and targeted delivery systems.

Research applications do not establish clinical suitability for the supplied grade.

Packaging Options

• 1 kg packs.

• 5 kg packs.

• 25 kg fiber drums.

Confirm pack size, inner packaging and availability when requesting a quotation.

Storage and Handling

Lactobionic acid absorbs atmospheric moisture, which can cause sticking, clumping or changes in powder consistency.

• Keep the original container sealed in a cool, dry place protected from sunlight.

• Close the packaging promptly after sampling or dispensing.

• Use clean, dry tools and minimize exposure to humid air.

• Avoid breathing dust or getting powder in the eyes; use suitable gloves and eye protection.

• Follow the supplied SDS and the batch-specific storage and retest information.

Frequently Asked Questions

Is a 98% assay enough to establish pharmaceutical suitability?

No. Assay alone does not establish pharmacopoeial compliance, sterility or suitability for a particular manufacturing process. Review the complete specification and relevant supporting documentation.

Can lactobionic acid replace a lactobionate salt by weight?

No. The free acid and salts differ in molecular weight, counterions and their effect on formulation pH. Check whether your formulation requires lactobionic acid, potassium D-lactobionate or calcium lactobionate.

Is there one recommended concentration for all skincare products?

No. Select the concentration together with final pH, product format and intended use. Validate stability and finished-product safety rather than copying a use level from another formulation.
