Question 1

What is Polyglyceryl-2 Dipolyhydroxystearate and what does it do in sunscreen?

Accepted Answer

Polyglyceryl-2 Dipolyhydroxystearate is a plant-derived emulsifier that stabilizes water-in-oil systems, the type of formula where water droplets are suspended in an oil base. In a sunscreen it helps hold that structure together and conditions the skin, which supports rich, water-resistant textures. It is the kind of emulsifier you see in creams and sticks meant to stay put through sweat and water.

Question 2

Is Polyglyceryl-2 Dipolyhydroxystearate safe?

Accepted Answer

Yes. Polyglyceryl esters are a well-regarded, gentle family of emulsifiers favored in natural-leaning and sensitive-skin formulas. At the levels used in sunscreen it is non-irritating for most people. As always, very reactive skin can patch test a new product first.

Question 3

Does Polyglyceryl-2 Dipolyhydroxystearate clog pores?

Accepted Answer

Generally no. It is not flagged as comedogenic in our data, and it functions as an emulsifier in modest amounts rather than as a heavy, pore-clogging oil. If a water-resistant sunscreen feels rich, that richness usually comes from the oils and waxes in the formula, not from this emulsifier.

Question 4

Does Polyglyceryl-2 Dipolyhydroxystearate feed fungal acne (malassezia)?

Accepted Answer

It can. This ingredient sits in the fatty ester and emulsifier lane, and the malassezia yeast behind fungal acne can use the fatty part of such esters as food. People actively managing fungal acne (malassezia folliculitis) may prefer to avoid it. For everyone else it is harmless, and this is one specific skin concern rather than a wider safety problem.

Question 5

What is Polyglyceryl-2 Dipolyhydroxystearate on an ingredient list (INCI)?

Accepted Answer

"Polyglyceryl-2 Dipolyhydroxystearate" is the full INCI name on the label, which describes a polyglycerin backbone joined to polyhydroxystearic acid. It is a mouthful, but it simply marks an emulsifier. You will usually find it among the texture and emulsifier ingredients, common in water-resistant creams and sticks.

Question 6

Is Polyglyceryl-2 Dipolyhydroxystearate natural or synthetic?

Accepted Answer

It is plant-derived but lab-made. Its building blocks come from plant sources such as glycerin and fatty acids, but they are joined through processing to create the finished emulsifier, which does not occur ready-made in nature. So it is best described as naturally sourced and then refined.
