Calcium Chloride Dihydrate ●
TL;DR. This ingredient is used mainly as an electrolyte and viscosity adjuster in water-based formulas. It helps tune ionic strength, stabilize certain gel systems, and can contribute a slightly astringent skin feel.
What does Calcium Chloride Dihydrate do in a cosmetic formula?
This ingredient is used mainly as an electrolyte and viscosity adjuster in water-based formulas. It helps tune ionic strength, stabilize certain gel systems, and can contribute a slightly astringent skin feel.
Is Calcium Chloride Dihydrate clean?
From a clean-beauty perspective, it is generally low-concern at typical cosmetic use levels and is not a common restricted-list ingredient. Higher concentrations can feel drying or irritating, especially on compromised skin, so use level and formula context matter.
Is Calcium Chloride Dihydrate sustainable?
This material is an abundant inorganic mineral-derived salt, often sourced from brines or produced as an industrial co-product. It does not biodegrade in the organic-chemistry sense, but it dissociates in water and is not considered a persistent organic pollutant or bioaccumulative material.
Is Calcium Chloride Dihydrate COSMOS-approved?
It is generally compatible with COSMOS-natural and COSMOS-organic formulation rules when it meets purity and processing requirements for permitted mineral ingredients. Its Green Chemistry profile is strongest on simplicity, low bioaccumulation concern, and water compatibility, though it is not renewable in the plant-based sense.
How does Calcium Chloride Dihydrate work chemically?
The molecule is a hydrated crystalline electrolyte that dissociates readily in water into divalent cations and simple counterions, which can strongly affect polymer swelling, surfactant viscosity, and emulsion stability. It is typically used at low levels for ionic adjustment rather than as a headline active, and formulators need to account for its high water solubility and its tendency to disrupt salt-sensitive thickeners.
