Safe for Sensitive Skin: Yes

SAFETY & COMPATIBILITY

Safety Profile: Excellent safety profile. ewg score: 1.

Works Well With: Humectants,ceramides,actives as carrier

Avoid Combining With: No significant incompatibilities

SCIENTIFIC NOTE

Dimethicone's exceptional silky feel arises from its very low intermolecular attractive forces (weak van der waals forces due to non-polar methyl groups) that allow silicone chains to slide freely over skin. the coefficient of kinetic friction for pdms against skin (~0.04) is among the lowest of any cosmetic material – explaining why even small amounts transform product feel.

DESCRIPTION

What It Does: Prevents microbial contamination that would otherwise render water-containing cosmetics unsafe — inhibiting bacterial, fungal, and yeast growth through membrane disruption, enzyme inhibition, or metabolic interference at permitted regulatory concentrations.

Why It's Used: Preservatives are safety-critical — un-preserved water-containing cosmetics can develop dangerous microbial contamination (pseudomonas aeruginosa eye infections, s. aureus skin infections) within days. preservation is a regulatory requirement, not an optional enhancement.

How It Works: Mechanism varies by class: organic acids (benzoic, dehydroacetic) disrupt intracellular ph in bacteria and fungi by proton flux across membranes; parabens inhibit membrane-associated enzyme function; chlorhexidine disrupts bacterial and fungal membrane integrity through divalent ion chelation of membrane phospholipids.
