FlavScents AInsights Entry for Poly(vinyl stearate) (CAS: 9003-95-6)

1. Identity & Chemical Information

Poly(vinyl stearate) is a synthetic polymer derived from the esterification of vinyl alcohol and stearic acid. It is commonly referred to by its CAS number 9003-95-6. The material does not have a FEMA number as it is not typically used in flavor applications. The molecular formula is (C20H40O2)n, where 'n' represents the number of repeating units, and the molecular weight varies depending on the polymerization degree. The polymer is characterized by long hydrocarbon chains, which contribute to its hydrophobic nature and influence its functional properties in formulations.

2. Sensory Profile

Poly(vinyl stearate) itself does not possess a distinct odor or flavor profile, as it is primarily used as a structural component rather than a sensory agent. Its role in formulations is more about modifying texture and stability rather than imparting any sensory characteristics. Therefore, it is not typically evaluated for odor or taste thresholds.

3. Natural Occurrence & Formation

Poly(vinyl stearate) is not naturally occurring. It is synthesized through the polymerization of vinyl stearate, which itself is produced by the esterification of vinyl alcohol with stearic acid. This synthetic pathway does not align with the criteria for "natural flavor" or "natural fragrance" designations, as it involves chemical synthesis rather than extraction from natural sources.

4. Use in Flavors

Poly(vinyl stearate) is not typically used directly in flavor formulations due to its lack of sensory properties. However, it may be used as a carrier or encapsulating agent in flavor delivery systems, where its hydrophobic nature helps protect volatile compounds. Typical use levels in such applications are not well-documented, but industry practices suggest concentrations are kept low to avoid altering the flavor profile of the final product. Stability under various conditions such as heat and pH is generally good, making it a reliable component in complex formulations.

5. Use in Fragrances

In fragrance applications, poly(vinyl stearate) serves as a fixative or a film-forming agent, helping to stabilize volatile fragrance components and prolong their release. It is used across various fragrance families and product types, including lotions and creams. Concentration ranges are typically qualitative, with the polymer being used in small amounts to avoid affecting the fragrance's volatility profile. Its contribution is primarily in the base note, providing longevity to the fragrance.

6. Regulatory Status (Regional Overview)

Poly(vinyl stearate) is not specifically regulated as a flavor or fragrance material. In the United States, it is not listed under FEMA GRAS for flavor use. In the European Union, it does not have a specific FL number under Regulation (EC) No 1334/2008. Regulatory status in the UK post-Brexit remains aligned with the EU for such materials. In Asia and Latin America, specific regulations for poly(vinyl stearate) in flavors or fragrances are not well-documented, indicating a need for formulators to verify compliance on a case-by-case basis.

7. Toxicology, Safety & Exposure Considerations

Poly(vinyl stearate) is generally considered safe for use in cosmetic and personal care products, with low potential for oral, dermal, or inhalation toxicity. It is not typically ingested, so oral exposure is minimal. Dermal exposure is common in fragrance applications, where it is not known to cause irritation or sensitization. Inhalation exposure is limited due to its low volatility. Overall, the risk profile is favorable, but formulators should ensure compliance with relevant safety standards.

8. Practical Insights for Formulators

Poly(vinyl stearate) is valued for its film-forming and stabilizing properties, making it useful in both flavor encapsulation and fragrance fixation. It synergizes well with other polymers and stabilizers, enhancing the longevity and stability of volatile compounds. A common pitfall is using excessive amounts, which can lead to undesirable textural changes. It is often under-utilized in formulations where enhanced stability is needed without altering sensory profiles.

9. Confidence & Data Quality Notes

Data on poly(vinyl stearate) is well-established in terms of its chemical properties and functional roles. However, specific sensory and regulatory data are less documented, reflecting its primary use as a structural component rather than a sensory agent. Industry practices are generally consistent, but formulators should verify specific regulatory requirements for their target markets.

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.
