Unilever has introduced what it claims to be the first packaging reduction initiative in aerosol deodorants since they were invented in the 1960s. The company has developed a compressed can technology that utilizes 50% of the propellant needed for its predecessor can, effectively reducing the can size by half.
The new 75 ml cans also require 25% less aluminum and reduce the carbon footprint of the product by an estimated 35% as well. The cans will initially be used for the Sure, Dove and Vaseline brands but may be used for the company's other lines. Although the cans will be half the size, they are said to last just as long as the 150 ml cans.
“Unilever is becoming a leader in sustainability and we believe that this new innovation represents a genuine shift change in the way aerosol deodorants can be manufactured. The reduced environmental impact of providing consumers with a smaller can will take us another step closer to realizing our global ambition of doubling the size of our business while reducing our environmental impact, " noted Amanda Sourry, chairman of Unilever UK and Ireland.
The new cans are a result of years of research and leading-edge innovation, which will allow Unilever to make positive progress towards two of its Unilever Sustainable Living Plan targets: to halve the greenhouse gas impact of products across the lifecycle by 2020 and to halve the waste associated with the disposal of products by 2020.
The development of grittiness in a certain cosmetic emulsion is caused not by a lack of energy input, but rather by the application of too much energy intended to solve the problem caused by a slow crystal growth. While it is true that in many emulsions, application of additional thermal and mechanical energy in the form of heating and mixing will generally reduce the average droplet size, in some formulations, it promoted supersaturation and slow crystal growth which degraded product quality.Read more sample pages from Chapter Fourteen of Manufacturing Cosmetic Emulsions: Pragmatic Troubleshooting and Energy Conservation by T.
