Isochrysis Galbana Extract ●

TL;DR. This ingredient is primarily a skin-conditioning extract, used to add antioxidant, soothing, and hydration-supporting properties to creams, serums, and masks. Its value comes from naturally occurring pigments, lipids, amino acids, and polysaccharide fractions.

What does Isochrysis Galbana Extract do in a cosmetic formula?

This ingredient is primarily a skin-conditioning extract, used to add antioxidant, soothing, and hydration-supporting properties to creams, serums, and masks. Its value comes from naturally occurring pigments, lipids, amino acids, and polysaccharide fractions.

Is Isochrysis Galbana Extract clean?

It is generally compatible with clean-beauty standards and is not a common restricted-list concern. The main quality questions are extraction solvent, preservative system, trace contaminant testing, and batch-to-batch standardization.

Is Isochrysis Galbana Extract sustainable?

This material is usually sourced from cultivated marine biomass, which can reduce pressure on farmland and freshwater compared with many land crops. Its sustainability profile depends on cultivation method, drying energy, and extraction process, while the organic fractions are expected to be biodegradable.

Is Isochrysis Galbana Extract COSMOS-approved?

It can be permitted under COSMOS-natural and COSMOS-organic when made with approved physical processes or allowed solvents and preserved with compliant systems. From a Green Chemistry view, it aligns well when sourced from renewable cultivation and extracted with water, ethanol, glycerin, or other lower-impact media.

How does Isochrysis Galbana Extract work chemically?

This compound is a complex biological extract rather than a single molecule, with polar polysaccharides and amino acid derivatives in water-rich extracts and more pigment or lipid content when less polar extraction is used. Typical cosmetic use is often around 0.1% to 5%, and pigment-rich or unsaturated fractions benefit from protection against heat, light, oxygen, and metal-catalyzed oxidation.
