Butylphenyl Methylpropional

What Butylphenyl Methylpropional is & what it does

A floral fragrance compound (Lilial) once widely used, now restricted in many regions. It is a labeled allergen.

What is Butylphenyl Methylpropional and what does it do in sunscreen?

Butylphenyl Methylpropional is a synthetic fragrance compound, long known by the trade name Lilial, that adds a soft floral, lily-of-the-valley scent. In a sunscreen it plays no role in sun protection; it is there only to make the product smell pleasant or to mask the raw smell of the UV filters and oils. It is one of the named fragrance allergens that must be declared on the label rather than hidden inside the word Fragrance.

Is Butylphenyl Methylpropional safe?

For most people it causes no problem at the levels used in cosmetics, but it is a recognised fragrance allergen, and that safety profile led the EU to restrict it. Because of those concerns it has been phased out of cosmetics sold in the European Union, and many brands worldwide have reformulated to drop it. If your skin tolerates fragrance, an older product containing it is unlikely to bother you, but it is not an ingredient new formulas are reaching for.

Why is Butylphenyl Methylpropional listed separately on the label?

Because it is one of the fragrance ingredients regulators require to be named individually when present above a small threshold, instead of being folded into the generic word Fragrance or Parfum. Seeing it spelled out does not mean there is a lot of it; it means the rules ask for transparency on this specific allergen. That labeling is meant to help people who know they react to it avoid it.

Is Butylphenyl Methylpropional bad for sensitive skin?

It can be, since it is a labeled fragrance allergen and fragrance is one of the more common triggers of irritation and allergic contact dermatitis. People with sensitive, reactive, or compromised skin are the ones most likely to notice it, while everyone else usually tolerates it fine. If you are prone to reactions, choosing a fragrance-free sunscreen is the simpler way to avoid it.

Does Butylphenyl Methylpropional clog pores?

Generally no. It is a volatile scent molecule used in tiny amounts, not a heavy oil or wax, so it is not a typical pore-clogging ingredient. The concern with it is allergy and irritation rather than breakouts; if a product is causing congestion, the richer emollients in the formula are the more likely cause.
