Ingredient review
Polyglyceryl-5 Polyricinoleate
INCI: Polyglyceryl-5 Polyricinoleate
A gentle, plant-based emulsifier that helps create stable, non-greasy lotions and creams.
In plain English
This ingredient is a helper that allows water and oil to mix together smoothly in your skincare products. Without it, your lotion or cream would separate into watery and oily layers. It's made from castor oil and glycerin, so it's considered gentle and unlikely to clog pores or cause irritation.

Quick decision guide
Useful, but context matters
Polyglyceryl-5 Polyricinoleate is generally a lower-concern ingredient when the full formula suits your skin.
Plain-English read
Treat this as a practical screening step before you compare products that contain this ingredient.
- Step 1Start with the score, then check the irritation and clogging risk before judging Polyglyceryl-5 Polyricinoleate.
- Step 2Use the "Best for" and "Use caution if" sections to match the ingredient to your skin, not just to a marketing claim.
- Step 3If a product stings, breaks you out, or worsens irritation, judge the finished formula and stop using it even if the ingredient scores well.
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
Polyglyceryl-5 Polyricinoleate is a semi-synthetic emulsifier created by combining polyglycerin (derived from glycerin) with polyricinoleic acid (derived from castor oil). It belongs to a family of mild, skin-friendly emulsifiers often used in natural and sensitive-skin formulations.
How it works
It works by reducing the surface tension between oil and water, allowing them to form a stable, uniform mixture. This creates a smooth, creamy texture that spreads easily on the skin and helps active ingredients deliver more evenly.
Pros
Gentle on skin
Polyglyceryl-5 Polyricinoleate has a very low irritation risk, making it a good choice for sensitive skin types and daily-use products.
Non-comedogenic
It does not tend to clog pores, so it's suitable for acne-prone or oily skin when used in properly formulated products.
Cons and cautions
Not a treatment ingredient
This is an emulsifier, not an active ingredient. It won't directly hydrate, exfoliate, or brighten your skin.
Formula-dependent performance
Its effectiveness depends on the overall formula. In some extreme pH or oil ratios, it may not stabilize the product as well as other emulsifiers.
Best for
- Anyone looking for gentle, non-irritating moisturizers or cleansers
- People with sensitive or acne-prone skin who want to avoid pore-clogging emulsifiers
Use caution if
- Those seeking a direct active ingredient for anti-aging or brightening — this is a formulation helper, not a treatment
