FlavScents AInsights Entry for PPG-9 Laurate (CAS: 9035-84-1)

1. Identity & Chemical Information

• Common Name(s): PPG-9 Laurate
• IUPAC Name: Polypropylene glycol laurate
• CAS Number: 9035-84-1
• FEMA Number: Not applicable
• Other Identifiers: Not available
• Molecular Formula: Not applicable (polymeric compound)
• Molecular Weight: Variable (depends on polymer length)
• Functional Groups and Structure–Odor Relevance: PPG-9 Laurate is a polymeric ester, typically used for its emollient and surfactant properties rather than its odor profile. The laurate moiety may contribute to a mild, fatty odor, but this is not its primary function.

2. Sensory Profile

PPG-9 Laurate is primarily used for its functional properties rather than its sensory characteristics. It may impart a subtle, fatty odor due to the laurate component, but this is generally considered negligible in formulations. The compound is not typically used for its flavor or fragrance impact, and specific odor or taste thresholds are not well-documented.

3. Natural Occurrence & Formation

PPG-9 Laurate is a synthetic compound and does not occur naturally. It is produced through the esterification of lauric acid with polypropylene glycol. This process does not align with "natural flavor" or "natural fragrance" designations, as it involves synthetic polymerization.

4. Use in Flavors

PPG-9 Laurate is not commonly used in flavor applications due to its primary role as an emulsifier and surfactant. When used, it serves to stabilize emulsions in flavor systems rather than contributing to flavor profiles. Typical use levels in food are not well-documented, but when used, they are generally low, often below 100 ppm, to avoid altering the sensory characteristics of the product.

5. Use in Fragrances

In fragrance formulations, PPG-9 Laurate acts as a solubilizer and emollient, helping to blend and stabilize fragrance oils. It is used across various fragrance families and product types, including lotions and creams. Concentration levels vary but are typically low, often less than 1% of the total formulation, to maintain product stability without impacting the fragrance profile.

6. Regulatory Status (Regional Overview)

• United States: Not specifically listed as GRAS by FEMA; used under general safety guidelines for cosmetic ingredients.
• European Union: Not specifically listed under Reg. (EC) No 1334/2008; used in cosmetics under the Cosmetics Regulation.
• United Kingdom: Follows EU guidelines post-Brexit; no specific divergence noted.
• Asia: Usage varies; generally accepted in cosmetics with adherence to local regulations.
• Latin America: Usage in cosmetics is generally accepted, with specific regulations varying by country.

7. Toxicology, Safety & Exposure Considerations

• Oral Exposure: Limited data available; primarily used in non-ingestible applications.
• Dermal Exposure: Considered safe for use in cosmetics; low irritation potential. Not listed by IFRA as a sensitizer.
• Inhalation Exposure: Low volatility reduces inhalation risk; primarily a concern in occupational settings during manufacturing.

Overall, PPG-9 Laurate is considered safe for its intended uses, with a low risk profile in both food and fragrance applications.

8. Practical Insights for Formulators

PPG-9 Laurate is valued for its ability to stabilize emulsions and improve the texture of formulations. It synergizes well with other emulsifiers and surfactants. A common pitfall is using it in concentrations that affect the sensory profile of the product. It is often under-utilized in formulations where enhanced stability is needed without altering the fragrance or flavor.

9. Confidence & Data Quality Notes

Data on PPG-9 Laurate is well-established in terms of its functional properties and safety in cosmetic applications. However, there is limited documentation on its use in flavor systems. Industry practices are generally consistent, but specific regulatory approvals may vary by region.

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.
