Inositol ●
TL;DR. This ingredient is used mainly as a water-soluble humectant and skin-conditioning agent, helping formulas hold water at the surface and leave a smoother feel. In hair care, it can also add light conditioning without oiliness.
What does Inositol do in a cosmetic formula?
This ingredient is used mainly as a water-soluble humectant and skin-conditioning agent, helping formulas hold water at the surface and leave a smoother feel. In hair care, it can also add light conditioning without oiliness.
Is Inositol clean?
Clean-beauty frameworks generally view it as low-friction, with a low sensitization profile and no common restricted-list concerns. It is typically well tolerated, including in leave-on skin care at standard use levels.
Is Inositol sustainable?
This material is commonly sourced from plant carbohydrates or fermentation-based routes, with corn and rice-derived supply chains being common. It is water-soluble and readily biodegradable, with little concern for environmental persistence.
Is Inositol COSMOS-approved?
It is generally permitted under COSMOS natural and organic standards when sourced and processed from approved natural raw materials. Its renewable sourcing, biodegradability, and aqueous processing profile align well with Green Chemistry principles.
How does Inositol work chemically?
The molecule is a small cyclic polyol, a six-carbon ring bearing six hydroxyl groups, which explains its high water solubility and humectant behavior. It is typically used around 0.1% to 2% in skin and hair care, remains stable across normal cosmetic pH ranges, and is not especially prone to oxidation.
