VEEGUM® R is the original, economical and most widely used grade of VEEGUM®. These products are water-washed smectite clays that serve as suspension stabilisers, emulsion optimisers and rheology modifiers. This also reduces the slippery or sticky feel of gums and polymers, while providing a silky, tack-free feel in topical preparations.

This study was designed to test the foamability, adhesion & fragrance retention capacity of the formulation with and without the addition of VEEGUM® R.
Foam Ability & Bubble Size
The foaming test was conducted and compared against each other as shown below. The formulation containing VEEGUM® R had small compact bubbles with high volume.
Also, the foam was quite stable overtime for almost 20 mins as seen here.
Whereas the one without VEEGUM® R had large loose bubbles and the foam collapsed relatively quickly.
The developed formulations were then sprayed on a vertical wall to check its adhesion for cleaning purposes.
The formulation with VEEGUM® R had better adhesion property than the formulation without the VEEGUM® R.
Fragrance Delivery
A sensory panel evaluation was conducted with 5 panelists to compare the fragrance1 intensity overtime for both the developed formulations.
Each formulation was placed at room temperature (~25oC) and accelerated stability in an incubator at a temperature of 45oC for 4 weeks. Below are the results from the panel evaluation.
Two surfactant systems were developed with one formulation containing VEEGUM® R and the other formulation without it. Adding VEEGUM® R to the formulation didn’t return a clear formulation. However, the vertical adhesion & fragrance intensity was better. Also, the foam was stable with tight bubbles compared to the formulation without the VEEGUM® R.
Study conducted in A S Harrison & Co Customer Experience Laboratory (CEL).
The CEL, based on site at Brookvale, NSW, was opened in early 2020 and provides exceptional support to our team of technically qualified commercial managers.
The CEL strengthens our ability to provide solutions needed by our customers and supply partners in end-use product development, formulation design techniques, product launch, field trial management and product testing.

Product and customer insights
CHALLENGE A power plant relying on ultrafiltration (UF) and reverse osmosis (RO) faced a critical operational challenge. A wastewater treatment upset severely fouled the UF system, drastically reducing water production. Despite multiple cleaning attempts with sodium hypochlorite and citric acid, transmembrane pressure (TMP) remained high, and flux showed no improvement. The plant’s inability to meet […]
CHALLENGE A gold processing plant in New Zealand sought to improve gold recovery efficiency while addressing high Total Organic Carbon (TOC) levels. Elevated TOC increased the Preg-Robbing Factor (PRF), reducing the plant’s ability to efficiently recover gold during the Carbon-In-Leach (CIL) process. The traditional use of kerosene as a carbon blanking agent offered limited efficacy, […]
CHALLENGE A municipal water reuse plant processing 8 million gallons per day (MGD) experienced severe fouling and scaling issues, including calcium phosphate and silica deposits. With steep feed pressure increases and differential pressures in both stages, the plant required frequent cleanings every 4 to 6 weeks, amounting to 32 cleanings annually. Each cleaning cycle resulted […]
The plant was experiencing weekly shutdowns for fiber clean up (~ 3 kg bags of matted slurry is cleaned per week). The shut downs were costly as they reduce plant availability for production.
CHALLENGE A municipal reverse osmosis (RO) plant on Florida’s west coast, with a 20 MGD capacity, faced high operational costs due to its reliance on 93% sulfuric acid for pH adjustment. The plant used a combination of a brackish water reverse osmosis (BWRO) membranes and fiberglass-wrapped membranes across 10 trains, each operating at 75% recovery. […]
The International Maritime Organisation (IMO) regulation, known as IMO 2020 was the the largest change in regulation relating to marine fuels impacting 75% of the fuel used by the shipping industry.
Keeping drilling costs low using Redi-Guard™ High Performance, an ecologically friendly drilling fluid technology with revolutionary rheological and shale encapsulation properties
CHALLENGE A municipal reverse osmosis (RO) plant, with a capacity of 2 million gallons per day (MGD), faced frequent system cleanings, every 2-4 months, due to rising feed pressure. The plant, which sources water from brackish wells and uses Toray TMG-20D-400 membranes in a (16×7) -> (8×7) train configuration, was operating at 78% recovery. Despite […]
Research indicates that Sea Buckthorn may be able to strengthen the immune system. One in vitro study focused on the possible immunomodulatory properties of Sea Buckthorn.
AWC A-110 effectively inhibited scale at a dosage of 3.5 ppm and an operating pH of 6.9. This increase in operating pH reduced the district’s annual acid consumption by ~$350K per year based on their current production.
MCI® -2020 V/O and ChemMaster’s Colorsil were chosen to repair and protect the walls based on their 20 year warranties and the fact that together they could fulfill the other specified repair design requirements.
Despite numerous cleanings, the productivity of the Reverse Osmosis plant would not recover from severe membrane fouling. The membrane autopsy revealed that the ferric hydroxide was seeding
silica polymerization and that even while the ferric hydroxide was removed, the silica scaling was continuing to grow.
The East Hokkaido region is known to have the highest volume of potato product in Japan. Unfortunately, a potato farmer in the area was experiencing a high rate of potato scab infection in his agricultural field.
