The LINDAL Group’s TRUSPRAY® technology – available worldwide – is the first aerosol solution designed to handle the highly viscous formulas used in popular personal care and household product categories, and cut propellant and solvent use by as much as 50 percent, according to Philip Brand, the company’s Global Marketing Director.

The eco-friendly, patented, TRUSPRAY technology offers improved spray quality, with low flow rates. Its reduced need for propellant and solvent allows for compact packaging that saves on materials and transportation cost, and enhances easy, on-the-go consumer use.

As a result, LINDAL Group’s TRUSPRAY technology represents an exciting, sustainable option for makers of viscous gels, waxes, concentrates, deodorants and more.

The LINDAL Group is a worldwide leader in the development and manufacture of valves, actuators and spray caps for aerosol products and renowned for its innovative solutions.

“Lindal’s TRUSPRAY opens exciting new product development opportunities for brand owners throughout the world,” Brand said. “Here is an innovative, new and better aerosol solution that significantly reduces the use of propellant, solvent and packaging materials, enhances the end-user experience, and offers compatibility with conventional, high-speed filling lines. The bottom line: greater economic returns, with heightened retail and consumer appeal,” he said.


LINDAL Group’s TRUSPRAY technological breakthrough is based upon the principle of capillary atomization, a highly efficient, four-phase, method of aerosol formation.

The process requires no flow-inhibiting swirl chambers or atomizer jets. The energy generated with each actuation is fully-utilized, for more complete aerosol formation that requires less propellant.

With TRUSPRAY, a standard valve is paired with a capillary tube. Upon actuation, product rises up the capillary wall, with only minimal use of propellant. Tiny droplets are “torn” from the formulation by the flowing propellant and travel – as aerosol – through the spray head’s bent capillary tube and out, as an even, deep, mist. With flow rates as high as 1g/10 sec., even hard-to-atomize bulk can be efficiently dispensed.


The efficiency of the TRUSPRAY technology permits a wide range of highly viscous products to be offered in aerosol form, with reduced propellant and solvent use and more compact overall package dimensions.

As a result, product development opportunities are opened in a wide range of product subcategories, including cosmetics and body care; sun protection; hair care and styling; household products and technical products.

“For example, viscous personal care products such as creams and lotions are easier to dispense and use,” said LINDAL Group’s Brand. “Suncare SPF products – whether oil, lotion, cream or gel – can be sprayed on evenly, with no missed spots, drips or waste, in compact, easily packed cans.

“Air travelers, too, will appreciate the reduced package size and enhanced convenience, along with users of household- and specialized products for the car or outdoors, such as waxes and pastes. The end-user experience is enhanced, the economic efficiencies are increased – and the need for less propellant and solvent, and reduced pack size, makes a statement and a real impact in today’s eco-conscious marketplace.

“The TRUSPRAY technology, in every way, is the sustainable aerosol solution,” Brand said.
