alpha aromatics®The unique fragrance niche known as Petrichor fragrances aims to capture the alluring scent of fresh rain, particularly the scent after a dry, humid spell of weather. Yes, it’s that specific, and as a perfume manufacturer and supplier, we understand the delicate balance required to replicate and introduce its evocative scent into products or product lines. In the following, we explore this esoteric fragrance type and the considerations guiding perfumers when incorporating it into soaps, candles, and other scented products.
What Exactly Is Petrichor?
This little known and strange sounding name is instantly recognized as the ethereal, pleasant smell of the first rain after a long spell of dry, humid weather.
In the 1960s, two Australian scientists, Isabel Joy Bear and Richard Thomas, coined the term as “blood of stones.
”Technically, the name derives from two ancient Greek words; petra, meaning stone, and ichor, which in mythology concerns the golden fluid that flows through the veins of the gods.
Three substances define the aromatic character of petrichor; namely, ozone, geosomin and plant terpenes especially, which are soil bacteria that are released from the soil and into the air via ozone.
Geosomin attracts humans and animals as well.
Some scientists claim that the aroma of petrichor is 200,000 times more potent in humans than the smell of blood in the sea is for sharks.
Down through the ages, mankind has relied on rain for survival, as its timeless cycle has always been the force behind replenishing lakes and reservoirs supporting crops and nourishing all life forms.
In addition, when rain evaporates, it leaves behind a residue of salt, which is a primary source of fresh water.
Camels in the desert depend upon petrichor to locate oases and other sources of water, and some species can even track the scent from as far as 50 miles away.
Petrichor’s aroma is never the same in any one place and greatly depends upon which part of the world the rain is falling, whether it is in a forest or urban environment, how strong the rainfall is and whatever surface it is striking.
What Does Petrichor Smell Like?
Who doesn’t feel a loving and primal connection with the earth after a storm?
It adds something to the air that whispers of continuity, new beginnings and a letting go of the past.
Master perfumers often seek to capture the elusive, enigmatic essence of petrichor because it serenades the psyche in a way no other scent can.
Its various elements are earthy, fresh, musky, damp and salty. Some people believe it is the actual smell of the rain itself, but it isn’t.
It occurs only when the rain hits the parched land and micro-organisms formerly hidden in the earth emerge, blended with the aromas of plant oils and ozone.
This aspect of nature, while only recently understood, is highly valued.
The sound, feel, appearance and smell of rain has inspired writers, poets and artists down through time.
In James Joyce’s 1916 Portrait of The Artist As A Young Man, he wrote how: “‘…the trees in Stephen’s Green were fragrant of rain, and the rain-sodden earth gave forth its mortal odour, a faint incense rising upward through the mould from many hearts.”
The Symbolic Nature of Rain And Soil
Since the days when the world was young, rain has been a boon to mankind and all living things.
Hunters and gatherers seeking food and water rejoiced in its occurrence as a sign from the great spirit in the sky that the cycle of life would continue.
It symbolizes transformation and renewal and a washing away of yesteryear’s dust.
Soil is existential as well as mystical and poetic for its connection to existence and the biological death and decay of microbes that in turn serve to feed life.
How Is Petrichor Used In Perfumery?
Petrichor has been used in perfume in India since 1911 where it is blended with creamy sandalwood and known as the ‘fragrance of life.’
It is also sometimes combined with potent patchouli, musty vetiver or green, mossy or woody facets that evoke the sensation of water on surfaces.
Perfume formulators are well aware that the intricate combination of so many organic molecules makes it impossible to snare all of them in a scent.
The process is painstaking, but well worth the effort.
Petrichor is the earthy, floral and natural life blood of spring and early summer, permeating the atmosphere with a warm, soft, viscerally familiar and comforting presence.
A Few Other Benefits of Petrichor
Rain makes modern life possible as a source of water for multiple industries including but not limited to:agriculture; electrical energy; perfume and hygiene.
The sounds of rain are relaxing and soothing to the human spirit.
Songs and poems down through time have extolled walking in the rain as a means of gleaning new perspectives.
A new rain opens a one-of-a-kind window into a different realm that lays hidden in the cold light of day.
Here, air is fresher and cleaner, shapes and colors diffuse into uniquely refracted light and blooms close their petals until they can once again bask in the warmth of the sun.
Symbolically, rain is acceptance of that which we cannot control, and as such, a new aspect of thought arises that speaks to the fact that other things in our lives are also beyond our control.

When introducing a fresh rain fragrance into a product line, our perfumers consider several factors.
Firstly, they need to ensure that the scent is authentic and evocative, capturing the earthy notes and subtle sweetness of petrichor.
Additionally, compatibility with the base of the product is crucial to maintain stability and longevity of the fragrance.
Moreover, the intensity of the scent must be balanced to create a pleasing olfactory experience without overwhelming the senses.
Perfumers may also experiment with complementary notes such as green foliage or floral undertones to enhance the complexity of the fragrance while maintaining its freshness.
By carefully considering these factors, perfumers can craft petrichor-infused products that not only captivate the senses but also evoke the soothing essence of a gentle rain shower, bringing a touch of nature’s tranquility into everyday life.
