Lactic Acid is an industrial ingredient used for organic acid for ph adjustment, acidification, and buffering support. in selected chemical formulation systems.
Lactic Acid is used in practical industrial formulations where organic acid for ph adjustment, acidification, and buffering support. are required. Grade selection should consider active matter or assay, impurity profile, physical form, pH range, compatibility, processing conditions, and supplier documentation. Typical values are screening guidance only and should not replace supplier specifications.
Commercial specifications vary by grade, impurity profile, concentration, physical form, and supplier documentation.
| Property | Value | Unit | Source / Method |
|---|---|---|---|
| Appearance | Clear to pale yellow liquid | N/A | Typical industrial range; verify supplier specification. |
| Assay | 80 - 90 | % | Typical industrial range; verify supplier specification. |
| pH | 1 - 3 | N/A | Typical industrial range; verify supplier specification. |
| Solubility Water | Water miscible | N/A | Typical industrial range; verify supplier specification. |
| Molecular Weight | 90.08 - 90.08 | g/mol | Typical industrial range; verify supplier specification. |
| Density | 1.18 - 1.22 | g/cm3 | Typical industrial range; verify supplier specification. |
status: avoid | Avoid incompatible oxidizing conditions unless supplier SDS supports use.
status: compatible | Typically used in aqueous systems with controlled dilution.
status: limited | Neutralization is exothermic and must be controlled.

Review and verify the supplier SDS/TDS before handling, scale-up, or commercial use. Concentrated lactic acid can irritate or burn skin and eyes; review supplier SDS/TDS.
Use must be assessed by product category, exposure route, impurity profile, and local requirements. Confirm current status from supplier documentation before market launch.
