This ingredient functions as an emollient and skin-conditioning lipid, helping soften skin and reduce transepidermal water loss. It also improves glide in oils, creams, balms, and hair-care formulas.

Question 2

Is Vitis Vinifera Seed Oil / Grape Seed Oil clean?

Accepted Answer

From a clean-beauty perspective, this ingredient is generally well tolerated, with low irritation potential for most users. The main quality considerations are freshness, oxidation control, and pesticide-residue management in conventional supply chains.

Question 3

Is Vitis Vinifera Seed Oil / Grape Seed Oil sustainable?

Accepted Answer

This material is plant-derived and often sourced from seeds left over from wine and juice production, which gives it a useful upcycling profile. It is biodegradable, but sustainability depends on agricultural practices, solvent versus mechanical extraction, and refining choices.

Question 4

Is Vitis Vinifera Seed Oil / Grape Seed Oil COSMOS-approved?

Accepted Answer

It is permitted under COSMOS-natural and can be used in COSMOS-organic formulas when the agricultural raw material is certified and processing meets the standard. It aligns well with Green Chemistry when mechanically pressed or extracted with approved low-residue methods, using renewable feedstock and biodegradable chemistry.

Question 5

How does Vitis Vinifera Seed Oil / Grape Seed Oil work chemically?

Accepted Answer

This ingredient is a triglyceride-rich botanical lipid with a high share of linoleic acid, plus oleic acid, tocopherols, and phytosterols. It is typically used around 1-10% in emulsions and up to 100% in anhydrous oils, and its high polyunsaturated content means antioxidants and air-light control help manage oxidation.
