Supporting brands and manufacturers to innovate in the personal care and home care categories, suppliers of technology, ingredients and packaging components continue to raise the bar in the aerosols industry.
The Lindal Group, a global leader in aerosol packaging technology is helping drive product development in the innovation-driven worldwide shaving cream market, which is expected to reach nearly US$8 billion annually by 2018. The group was recently chosen by Unilever for its AXE branded Men’s Chilled Shave Gel.
Lindal components such as its Bag on Valve (BoV) solution and wave actuator for foam and gel products, selected by Unilever, turn unique packaging concepts into a reality. According to Philip Brand, global marketing director, growth in this particular personal care market segment is spurred by new formats and end-user experiences, as well as the demographic impact of young men, 15 years and older. ‘These younger guys are entering the global consumer market with increasing disposable income and growing interest in personal grooming – in both developed and emerging markets,’ he says.
‘They look for products that deliver high performance, have plenty of ergonomic appeal, and fit their active lifestyles. For brand owners, our aerosol solutions can make this happen, with optimal supply chain efficiency and the highest quality outcome.’
This modern packaging technology has been developed to improve the performance of a wide range of personal care and cosmetic products. It is convenient and user friendly, and can be sprayed evenly at all angles, with a 99 per cent evacuation rate.
With a BoV system, the product is placed inside the bag while the propellant is filled in the space between bag and can. The product – such as a gel, cream or spray - is dispensed by the propellant simply squeezing the bag when the actuator is depressed. As a result, the bulk maintains its integrity and remains separated from the propellant at all times. According to Stewart & Brierley, a South African company that has been the sole agent of Switzerland’s Pamasol for the last 40 years, because of the flammability of gas some customers are moving to BoV systems.
The filling of packaging with BoVs is done in two steps. First the BoV is inserted into the aerosol container. Pamasol’s Undercup Crimper raises the valve slightly and fills the propellant into the container between the valve and the cup rim before the container is closed with the valve.
Through its association with Pamasol, Stewart & Brierley brings leading aerosol and spray system technology to the South African market including filling, crimping and gassing solutions, from laboratory to high speed automatic machines up to 750 cans per minute, with water bath testing, valve inserting, spray button inserting and fully automatic capping systems.
In a report on users of deodorants in South Africa published in May 2014, Analytix Business Intelligence noted that between 2009 and 2013, white users decreased from 14 to 11 per cent. Black South Africans remain the majority users at 76 per cent in 2013.
Regardless of race or colour, for all consumers sweating is a natural process in the human body. The evaporation of sweat is an important mechanism for temperature control. However, controlling body odour and preventing sweat marks are key to consumers through the use of underarm products, such as antiperspirants, deodorants or combined systems. Antiperspirants fall within the definition of a cosmetic and are used to significantly reduce the amount of sweat. This reduction is achieved by using aluminium salts, primarily aluminium chlorohydrate (ACH), as astringent ACH provokes a constriction of the perspiratory glands. When aluminium salts are exposed to sweat they react with proteins occurring on the skin and form insoluble aluminium compounds.
These substances ‘plug’ the gland ducts with the effect to temporarily prevent sweat reaching the surface of the skin. Aluminium containing antiperspirants are presently believed by some socialist movements to contribute to the accumulation of aluminium in the human body. In the opinion of the Scientific Committee on Consumer Safety, an independent group of experts advising the European Commission, no firm conclusion can be drawn due to absence of adequate data on dermal penetration. However, for consumers who want to avoid aluminium salts, pure deodorants are an excellent alternative.
With this in mind, Schülke, an international chemical and pharmaceutical company represented in South Africa by Savannah Fine Chemicals, has developed a new deodorant agent, sensidin DO. According to Schülke, sweat actually is an odourless secretion. Bodily malodour only develops when microorganisms transform sweat into volatile components like short-chain fatty acids, therefore generating unpleasant odour. For this reason deodorants are developed with antimicrobial ingredients to act against the involved Gram-positive bacteria, effectively preventing body odour. Sensidin DO is said to provide outstanding activity against these Grampositive bacteria. This sophisticated blend combines the well-known deodorant and skin care properties of ethylhexylglycerin with the antimicrobial capacity of octenidine HCl. Owing to the synergistic effect low concentrations of the active deodorant agent are required to ensure effectual protection. It is also proven gentle and mild to the sensitive axillary skin, even after shaving. Sensidin DO offers broad application capabilities including aerosols, roll-ons and non-stearate-based stick formulations.
For antiperspirant-deodorants (APD) it is a compatible combination partner to aluminium chlorohydrate. APD applications are on the rise, because they meet the demands of consumers who not only require odour prevention and reduction of sweat, but also want to expose their skin to the least amount necessary of aluminium salts.
