Question 1

What does Perilla Frutescens Seed Oil do in a cosmetic formula?

Accepted Answer

This ingredient primarily functions as an emollient and skin-conditioning lipid, helping soften the skin and support barrier feel. It can also act as a carrier for oil-soluble actives and pigments.

Question 2

Is Perilla Frutescens Seed Oil clean?

Accepted Answer

This ingredient is generally well-tolerated and has little clean-standard friction when fresh and properly refined or cold-pressed. The main watchpoint is oxidation, since highly unsaturated lipids can develop odor and skin-sensitizing breakdown products over time.

Question 3

Is Perilla Frutescens Seed Oil sustainable?

Accepted Answer

This ingredient is plant-derived from an agricultural it crop and is biodegradable. Its sustainability profile depends on farming inputs, regional sourcing, extraction method, and freshness controls, but it has no major persistence or bioaccumulation concern.

Question 4

Is Perilla Frutescens Seed Oil COSMOS-approved?

Accepted Answer

This ingredient is permitted in COSMOS-natural and COSMOS-organic products when sourced and processed according to the standard, especially through physical extraction. It aligns well with Green Chemistry principles because it is renewable, biodegradable, and can be produced with relatively simple processing.

Question 5

How does Perilla Frutescens Seed Oil work chemically?

Accepted Answer

This ingredient is a triglyceride mixture notable for a high polyunsaturated fatty acid profile, often rich in alpha-linolenic acid at roughly 50% to 65%, with smaller amounts of linoleic and oleic acids. It is commonly used around 1% to 20% in emulsions or higher in anhydrous products, and it benefits from antioxidants, low-oxygen headspace, and opaque packaging because it is oxidation-prone.
