Gelatin (also known as Collagen Hydrolysate) is a natural protein and peptide mix made from collagen by thermal hydrolyzation, used in food and medicine since the Egyptian civilization. It's a unique multifunctional ingredient with many beneficial effects in skin care applications; it acts as a gelling agent, thickener, stabilizer, film forming, and humectant.
In contrast to most other natural proteins, gelatin is a non-allergenic and safe ingredient that has no E-number used to identify EU-permitted food additives. Furthermore, the WHO considers gelatin a safe ingredient for food and topical application.
Collagen booster and NMF
Being a perfect source of amino acids (18 different amino acids, including seven essential), gelatin provides building blocks for collagen production in balanced proportions. As a result, it replenishes the skin's natural moisturizing factors (NMFs), exposing a firmer, smoother, and healthy appearance. In addition, collagen hydrolysate improves the skin's water-binding ability, providing volume, elasticity, and density.
Besides the skin, it's a perfect ingredient for nail, scalp, and hair care, exposing the natural beauty and improving the manageability and shine. Gelatin smoothes the outer layer of the hair (cuticle), coating and providing brightness, combability, and volume. It also penetrates the cortex, integrating with structure and recovering damaged hair.
With pH close to neutral, gelatin is a perfect agent for encapsulation protecting ingredients from oxidation and other influences like an envelope. In addition, it microencapsulates unstable vitamins and other elements in multiple complexes for high-end skincare products.
Easily solved in warm water, without any chemical reactions, it simplifies the gel formulation manufacturing process and allows manufacturers to label the product as organically produced only from raw materials approved fit for human consumption. In addition, Gatlin forms a 100% reversible gel compatible with most other hydrocolloids and ingredients, improving the overall quality, sensory profile (no stickiness or sliminess), and texture of finished products.
