Science
Mechanism of Action
Ceresin operates by forming a network of micro-crystallites that crosslink to provide a stable scaffold within emulsions and anhydrous products. On the skin, it creates a breathable, hydrophobic film that significantly reduces transepidermal water loss (TEWL) while preventing the 'bleeding' or separation of liquid oils in the formula.
Research
Clinical Evidence
High confidence6%
Key findings
- 01 Clinical evaluations conducted by the CIR confirmed that concentrations of 6% are non-sensitizing and non-irritating to human skin.
- 02 Engineering data demonstrates that 2-3% concentrations are sufficient to establish a rheological network for matrix stabilization.
- 03 Safety surveys indicate that concentrations as high as 48% in color cosmetics remain dermatologically inert.
Transparency
Dusting Analysis
Ceresin is a functional texturizer and stabilizer rather than an 'active' ingredient. Because its utility is tied to the physical structure of the product, it is rarely included at sub-functional levels for marketing purposes.
The Formula
Formulation
Stability
Extremely stable due to its saturated hydrocarbon structure; it is chemically inert across a wide pH range and possesses a melting point between 60°C and 95°C.
