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.

Color Me Beautiful…ZTip+™ 2018 Launch Announced

How do you take the world’s most advanced protective brush tip and make it better?

By adding a little bit of creative color, of course. Now, for the first time, Sanderson MacLeod proudly announces the ZTip+, offering the color identification and branding alignment previously only available from traditionally molded brush tips. Imagine…All of the variety, colors and consistency of an insert molded tip without but without the separation risks, production costs or tooling lead times of traditional molding.

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.

    Patents Assigned to Sanderson MacLeod, Inc.

    TWISTED IN WIRE BRUSH HAVING A MOLDED TIP AND METHOD OF ASSEMBLY THEREFOR

    Publication number: 20170258214
    Abstract: A brush includes a wire core, a round tip formed on a distal end of the wire core, the round tip being unitary with the wire core section and being formed by melting or welding a portion of the wire core at the distal end, and a molded tip attached to the wire core at the distal end via a ball-and-socket connection.

    Homogeneous core wire protective cleaning tip Patent number: 8850650

    Abstract: A brush for use on sensitive surfaces includes a twisted wire core having a handle end and a bristle end, and a plurality of bristles extending radially outward from a portion of the wire core defining a bristle block. The brush further includes a protective tip integrally formed on the wire core at the bristle end for preventing the brush from damaging sensitive surfaces. The wire core and the protective tip are formed from the same material.

    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.
