BRUSH PATENTS
AND INVENTIONS
Invented the Twisted Wire Mascara Brush
Within a year of Ken Sanderson and Bruce MacLeod starting this company with three employees and a few basic machines in 1958, at the request of a Hollywood make-up artist, Sanderson MacLeod invented the first twisted wire mascara brush. It soon became an industry standard and was widely developed by major cosmetic companies.
Invented the ZTip™
When Sanderson MacLeod’s customers needed a better brush tip, the company searched beyond the brush industry and found the answer in material joining science. The result is a new manufacturing process using high energy fusion welding technologies to melt a pre-constructed core wire section of a twisted wire brush into a consistent, smooth and inseparable protective tip – the ZTip – in a fully automated inline process.
Sanderson MacLeod has innovated countless new brush applications for wholesale cosmetic brushes, medical brushes, firearm cleaning and cleaning brushes. These ground breaking technologies also include snap off medical brushes. Working with top engineers in the extrusion industry, Sanderson MacLeod has developed a propriety method of printing and scoring a rod so that the sampling end snaps off.
We found a way, by adding color-coating to the tips
Introducing the ZTip+, which gives you all of the amazing qualities of the ZTip and allows you to color-identify specific brushes for certain applications. By color-coating the tips, you’ll save time, reduce brush selection errors, and gain efficiencies in device cleaning.
We are ready to help you with your brush innovation and supply.
Whether you have a current brush and want to take advantage of Sanderson MacLeod’s large volume direct manufacturing pricing or want to work with our team of engineers on a new design, we have you covered.

Mascara brush construction Patent number: 5551456
Abstract: An applicator brush for fluid-type cosmetics, such as may be used in applying mascara to eyelashes which includes a bristle portion disposed at one end of a helical twisted wire core with a handle disposed at the outer end. The configuration of the bristle portion is such that the bristle tips define a generally cylindrical outer surface having two (2) diametrically opposed channels and application surfaces helically disposed along the length of the brush portion which are spiraled about the core to form a helix thereof. The brush portion is formed by disposing the bristles between the lengths of the wire and helically twisting the wire to form the core that retains the bristles therebetween. The bristle portion is then trimmed to a shape of generally rectangular cross-section. To form the helical application surface, the wire core is further twisted in the same direction a predetermined number of turns.

Mascara brush Patent number: 4733425
Abstract: Mascara brush construction composed of a plurality of radially extending bristle filaments fastened in brush formation by a helically twisted metallic wire core. The bristles are tubular or hollow polyamide filaments, each crimped at the midpoint of its length by portions of the helically twisted wire so that the filament halves flare outward in various directions from the brush core. In an alternate embodiment the filaments are noncircular in cross-section and include a plurality of longitudinal, radially extending flange portions.
