From perfumery to skincare, sun care, or makeup, all cosmetics categories come with the spray option for their final packaging. Albéa France’s Étienne Brière, Marketing Director Fine Mist, and Jean-Pierre Songbe, Innovation & Development Expert, came to the 12th edition of the PCD show (Packaging of Perfumes, Cosmetics & Design) to reveal what lies behind a ‘hiss’.
What is a spray?
To provide a technical answer to this question, Étienne Brière first gave details on the seven main features of a spray:
1/ Droplet size and distribution
‘A droplet can be 30 micrometres to 1 millimetre in diameter’, the speaker explained. Its impact on the consumer’s perception varies depending on its size: for example, the thinner the droplets, the drier the spray on the user’s skin.
2/ Spray angle
It can be of 30°, 40°, or 60°, bearing in mind that a reduced angle makes it possible to target specific areas (arms, legs, armpits, etc.), while a large angle is more efficient for immersing oneself or touching larger areas like the chest.
3/ Spatial distribution
It helps verify the spray is homogeneous enough, round, and harmonious, and it does not generate any hollow inside.
4/ Spray length
It can measure from a few centimetres to more than a metre, depending on its application in the field of cosmetics.
5/ Spray speed
‘It is the speed with which a droplet impacts the skin of a consumer’, Étienne Brière explained. ‘It also determines the gentleness of the contact, an essential parameter, in particular for facial care applications.’
