HYDROLYZED SPINAL PROTEIN.

Insufficient Data CAS 91080-05-6 / ANTISTATIC, HAIR CONDITIONING, SKIN CONDITIONING

Hydrolyzed Spinal Protein is a fragmented protein derived from spinal tissue, broken down into smaller peptides and amino acids. These smaller components are designed to enhance skin absorption, offering potential benefits for skin conditioning, hydration, and barrier support. Its utility as a cosmetic ingredient, however, necessitates careful consideration due to the origin material.

Summary

Antistatic Hair Conditioning Skin Conditioning

Science

Mechanism of Action

As a hydrolyzed protein, this ingredient functions by delivering amino acids and peptides to the skin's surface. These small molecules are understood to aid in moisturizing the stratum corneum, enhancing the skin's overall hydration capacity. Furthermore, they contribute to supporting the skin's inherent elasticity and repair processes, while reinforcing the natural protective barrier to mitigate transepidermal water loss.

Stability

Hydrolyzed proteins generally exhibit pH-dependent solubility and stability. Solubility is typically minimal around their isoelectric point, often in the pH 4-6 range. Solubility tends to increase under more acidic or basic conditions; however, degradation or further hydrolysis can occur in strongly alkaline solutions, particularly above pH 8.5.

Safety

Safety Profile

CIR Status
Not reviewed
Sensitization risk Unknown

No specific safety assessment by the CIR Expert Panel or SCCS for 'Hydrolyzed Spinal Protein' in cosmetics was identified. The FDA has prohibited the use of cattle spinal cord in human food due to regulatory concerns, which, while specific to food, highlights potential issues with the source material. For other hydrolyzed proteins, the CIR Expert Panel has generally deemed them safe for cosmetic use provided they are formulated to restrict peptides to a weight average of 3500 Daltons (Da) or less, or not exceeding 30 amino acids in length, to mitigate sensitization risk. The safety profile of this specific ingredient in cosmetic applications remains unconfirmed without dedicated evaluation.

Verdict

Insufficient Data

While general hydrolyzed proteins offer skin conditioning benefits, the lack of specific cosmetic safety and efficacy data for Hydrolyzed Spinal Protein, coupled with regulatory concerns regarding its source material in other applications, renders its cosmetic suitability insufficiently documented for a confident recommendation.
