SODIUM CAPROOYL HYALURONATE.

Insufficient Data CAS - / FILM FORMING, SKIN CONDITIONING, SKIN PROTECTING

Sodium Caprooyl Hyaluronate is a precision-engineered derivative of hyaluronic acid, chemically modified with a caproyl group. This alteration enhances its inherent properties, allowing it to function as an advanced film-forming, skin conditioning, and protective agent.

Summary

Film-forming Skin conditioning Skin protecting

Science

Mechanism of Action

This ingredient operates by establishing a resilient, invisible film across the skin's surface. This protective barrier aids in conditioning the epidermis, minimizing transepidermal water loss, and offering generalized protection against environmental stressors. The unique caproyl modification is understood to amplify its performance beyond conventional hyaluronan structures.

Stability

The solubility of Sodium Caprooyl Hyaluronate is critically dependent on its degree of substitution (DS) and molecular weight (MW). Materials with a DS of 5-15% are fully water-soluble (up to 10% w/v for lower MW forms), while those with 15-40% DS are partially soluble, and 40-70% DS results in water insolubility (for higher MW). Stability is compromised by extreme pH values and elevated temperatures, which can induce molecular chain breakage and lower MW, particularly affecting higher MW material. It exhibits high sensitivity to free radicals and is prone to hydrolysis in both strongly acidic and alkaline conditions. For general sodium hyaluronate, optimal stability is observed between pH 5.5 and 8.0.

Conflicts

  • Amphiphilic cationic substances (e.g., cationic detergents)
  • High molecular weight positively charged substances (e.g., chitosan, quaternized polymers, certain proteins)
  • Free radicals
  • Extreme pH values
  • Heat

Safety

Safety Profile

CIR Status
Insufficient data
Sensitization risk Unknown

While the Cosmetic Ingredient Review (CIR) Expert Panel has affirmed the safety of general hyaluronates (including Hyaluronic Acid and Sodium Hyaluronate) in cosmetic applications, specific safety assessments and concentration limits for Sodium Caprooyl Hyaluronate itself are currently insufficient in available data. It is generally anticipated to share the favorable safety profile of its parent compounds.

Verdict

Insufficient Data

As a caproyl-modified hyaluronic acid derivative, this ingredient offers promising film-forming, conditioning, and protecting benefits; however, specific clinical efficacy and dedicated safety data for this particular compound are currently insufficient for a conclusive verdict.
