FlavScents AInsights Entry: Carbonic Acid, Lithium Salt (CAS: 10377-37-4)

1. Identity & Chemical Information

Common Name(s): Lithium carbonate
IUPAC Name: Lithium carbonate
CAS Number: 10377-37-4
FEMA Number: Not applicable
Other Identifiers: EINECS 233-841-9
Molecular Formula: Li2CO3
Molecular Weight: 73.89 g/mol
Functional Groups and Structure–Odor Relevance: Lithium carbonate is an inorganic compound with no direct odor relevance due to its ionic nature. It is primarily used in industrial applications rather than in flavor or fragrance contexts.

Citation hooks: FlavScents; PubChem; FEMA

2. Sensory Profile

Lithium carbonate does not possess any significant odor or flavor characteristics. It is typically odorless and tasteless, which limits its direct application in sensory-driven industries such as flavors and fragrances. Its role, if any, in formulations would be more functional or technical rather than sensory.

Citation hooks: FlavScents; peer-reviewed sensory literature

3. Natural Occurrence & Formation

Lithium carbonate is not naturally occurring in the sense of being found in biological systems or as a component of natural flavors or fragrances. It is typically derived from mineral sources such as spodumene, petalite, and lepidolite through mining and subsequent chemical processing. Its formation involves the extraction and purification of lithium from these minerals.

Citation hooks: FlavScents; food chemistry literature; EFSA/JECFA monographs

4. Use in Flavors

Lithium carbonate is not used in flavor applications due to its lack of sensory properties. It does not contribute to flavor profiles and is not recognized as a flavoring agent. Its use in food systems is more aligned with its functional properties, such as pH regulation or as a mineral supplement, rather than flavor enhancement.

5. Use in Fragrances

Similarly, lithium carbonate is not utilized in fragrance formulations. Its lack of volatility and odor means it does not contribute to fragrance profiles. It is not recognized as a fragrance ingredient and does not play a role in the olfactory characteristics of products.

6. Regulatory Status (Regional Overview)

United States: Lithium carbonate is not listed as a FEMA GRAS substance for flavor use. It is regulated primarily for its use in pharmaceuticals and industrial applications.
European Union: Under Regulation (EC) No 1334/2008, lithium carbonate is not listed as a flavoring substance. Its use is more common in industrial and pharmaceutical contexts.
United Kingdom: Post-Brexit, the regulatory status aligns with the EU, with no specific flavor or fragrance applications.
Asia: In countries like Japan and China, lithium carbonate is primarily regulated for industrial and pharmaceutical use, with no specific approvals for flavor or fragrance use.
Latin America: Similar to other regions, lithium carbonate is not recognized for flavor or fragrance applications.

7. Toxicology, Safety & Exposure Considerations

Oral Exposure: Lithium carbonate is used in pharmaceuticals for its mood-stabilizing properties. It is not used in flavors, and its oral safety profile is well-documented in medical contexts.
Dermal Exposure: There is limited data on dermal exposure, as it is not used in topical applications. It is not known to cause irritation or sensitization in typical use scenarios.
Inhalation Exposure: Inhalation is not a typical route of exposure for lithium carbonate in flavor or fragrance contexts. Occupational exposure limits are more relevant in industrial settings.

Citation hooks: EFSA; FEMA; PubChem; toxicology literature

8. Practical Insights for Formulators

Lithium carbonate's primary value lies outside the flavor and fragrance industries. Its applications are more relevant in pharmaceuticals and industrial processes. Formulators in these fields should be aware of its functional properties, such as its role in pH regulation and as a source of lithium ions.

Citation hooks: FlavScents; industry practice

9. Confidence & Data Quality Notes

The data on lithium carbonate is well-established in industrial and pharmaceutical contexts. However, its lack of application in flavors and fragrances means there is limited sensory and formulation data available. Regulatory and safety information is robust for its approved uses.

About FlavScents AInsights (Disclosure)
FlavScents AInsights integrates information from authoritative government, scientific, academic, and industry sources to provide applied, exposure-aware insight into flavor and fragrance materials. Data are drawn from regulatory bodies, expert safety panels, peer-reviewed literature, public chemical databases, and long-standing professional practice within the flavor and fragrance community. Where explicit published values exist, they are reported directly; where gaps remain, AInsights reflects widely accepted industry-typical practice derived from convergent sensory behavior, historical commercial use, regulatory non-objection, and expert consensus. All such information is clearly labeled to distinguish documented data from professional guidance or informed estimation, with the goal of offering transparent, practical, and scientifically responsible context for researchers, formulators, and regulatory specialists. This section is generated using advanced computational language modeling to synthesize and structure information from established scientific and regulatory knowledge bases, with the intent of supporting—not replacing—expert review and judgment.
