HYDROLYZED CALF SKIN.

Valuable CAS - / NOT REPORTED

A refined form of hydrolyzed collagen, Hydrolyzed Calf Skin acts as a sophisticated humectant and moisturizer, delivering essential amino acids and oligopeptides to the skin. This ingredient plays a pivotal role in enhancing the skin's natural capacity for hydration, elasticity, and cellular regeneration.

Summary

moisturizer/humectant emollient skin conditioning skin regeneration support

Science

Mechanism of Action

This ingredient operates by drawing and binding water to the skin, thus acting as an effective humectant that enhances plumpness and elasticity. It supplies free amino acids, crucial building blocks for endogenous collagen and elastin synthesis. Furthermore, its oligopeptides function as ligands, signaling fibroblasts to augment the production of new collagen, elastin, and hyaluronic acid, thereby promoting significant skin regeneration and overall dermal health.

Key findings

  1. 01 Topical application of a 10% solution of Hydrolyzed Collagen (MW 1500 Da) demonstrated a reduction in UV-induced erythema, indicating a protective or soothing effect.
  2. 02 Cosmetic matrices, including emulsions and gels formulated with 0.5% to 1.5% collagen hydrolysates from various animal sources, showed measurable improvements in skin hydration and a visible reduction in periorbital wrinkles.
  3. 03 Hydrolyzed bovine collagen has been observed to enhance skin elasticity, hydration, and overall appearance, while actively supporting skin regeneration to aid in the recovery from imperfections such as blemishes and scars.

Stability

Hydrolyzed calf skin is highly soluble in water and exhibits stability within a pH range of 5.0-7.5 at 25°C. Enzymatic hydrolysis is often favored for its specific and mild processing conditions. For optimal skin health, topical products containing this ingredient are generally recommended to be formulated within a pH range of 4.0 to 6.0.

Conflicts

  • Incapable of independent film formation; requires co-formulation with other biopolymers for film-forming applications.

Sensitization risk Low

The Cosmetic Ingredient Review (CIR) Expert Panel has deemed hydrolyzed collagen, encompassing bovine and other animal sources, as safe for use in cosmetics under current practices and concentrations. Human studies indicate no irritation at concentrations up to 50% in water solution. Although comprehensive systemic toxicity data (e.g., reproductive, developmental, genotoxicity, carcinogenicity) were not available, the panel did not anticipate adverse systemic effects from topical application.
