Siberian Pine Seed Oil Polyglyceryl-6 Esters
INCI: Pinus Sibirica Seed Oil Polyglyceryl-6 Esters
A lightweight, skin-softening ester that helps blend oils and water in formulas while leaving a silky, non-greasy feel.
In plain English
This ingredient is a modified version of oil from Siberian pine seeds, combined with polyglycerol to make it mix better with water. In skincare, it acts as an emollient—meaning it helps smooth and soften the skin—and as an emulsifier, which helps oil and water stay blended in a product. It feels light and silky, not heavy or sticky, and is generally very gentle on the skin.

Score terms in plain English
Irritation risk
lowLess likely to sting, burn, or bother most users, though sensitive skin can still react.
Clogging risk
lowLess likely to feel heavy or contribute to clogged pores for most skin types.
Evidence level
moderateThere is useful support, but formula details and claim strength still matter.
What it is
A semi-synthetic ester created by reacting Siberian pine seed oil with polyglycerol-6. The result is a mild, biodegradable emulsifier and emollient that is compatible with many skin types.
How it works
It sits on the skin's surface to fill in tiny gaps between skin cells, making the skin feel smoother and softer. As an emulsifier, it reduces the surface tension between oil and water, allowing them to mix into a stable cream or lotion without separating.
Pros
Lightweight feel
Unlike heavier oils, this ester absorbs quickly and leaves a silky, non-greasy finish, making it comfortable for daily use on the face and body.
Gentle emulsifier
It helps create stable creams and lotions without harsh detergents, reducing the risk of irritation for sensitive skin.
Cons and cautions
Limited safety data
While generally considered safe, there are fewer long-term studies on this specific ester compared to more common emulsifiers like cetearyl alcohol.
Potential allergen
Derived from pine seeds, it may trigger reactions in the rare case of pine nut allergy, though such allergies are uncommon.
Best for
- People with normal to dry skin looking for a light emollient
- Those who prefer plant-derived, biodegradable emulsifiers
Use caution if
- Individuals with a known allergy to pine nuts or pine seed oil
Usage tips
Safety summary
This ingredient is considered safe for cosmetic use at typical concentrations. It has low irritation and comedogenic potential, though individuals with pine nut allergies should exercise caution. Regulatory bodies have not flagged any significant safety concerns.
Research notes
Research on polyglyceryl esters in general supports their safety and mildness. Specific studies on Pinus Sibirica Seed Oil Polyglyceryl-6 Esters are limited, but the ingredient is structurally similar to other well-studied polyglyceryl esters used in cosmetics.
Common label clues
- Typical concentration
- 1–5% in leave-on products; up to 10% in rinse-off products
- Regulatory status
- Approved for use in cosmetics in the EU, US, and other major markets. No specific restrictions beyond general cosmetic safety requirements.
- Common uses
- Moisturizers, Serums, Cleansers, Body lotions
- Environmental note
- Siberian pine is a renewable resource, and the polyglycerol portion is typically derived from plant-based glycerin. The ester is biodegradable, making it a relatively eco-friendly choice.
Good to know
- This ingredient is often used in 'natural' or 'green' formulations because it is biodegradable and derived from renewable plant sources.
- It is not the same as pure pine seed oil—the polyglycerol modification makes it water-compatible and milder.
