Top Yield produces high-quality ancillary packaging elements that aid in the correct application of personal care products. Among its many items, it offers face masks for correct hygiene as well as other components to offer consumers a quick and easy way to apply creams, serums, and gels used in personal care treatments.

The rising star of the company's offering seems to be the material from which the treatment masks are created. Dubbed "Viceral" by the firm, the fabric is produced entirely from fine linter, the short fibres of the cotton boll that develop between the plant's seeds and its longer fibres which comprise about 10% of the boll's weight. Cotton linters are fine, silky fibres which adhere to the seeds of the cotton plant. This "cotton wool" has traditionally been used in applications not related to textiles, such as in paints or explosives, though recent developments allow it's use as a basic component of cellulose, paper, and cellulose-based fabrics, like Viceral.

Viceral is composed entirely of continuous cellulose filaments, markedly reducing the potential for lint and fallen-fibre formation and separation. It is soft, smooth, and gentle when in contact with the skin, making it the material of choice for applications ranging from medical gauzes and cosmetic pads to face masks and wipers for electronics and semiconductors. The material is inherently composed of smooth, rounded filaments, a finely ordered micro-structure, and an additive-free composition, which results in a very low amount of surface abrasion when using it. Viceral abrasion on a simulated skin surface is minimal even after repeated wiping, in contrast with the cumulative abrasion caused by other fabrics, such as normal cotton or rayon. As such, it is one of the smoothest natural fabrics available, perfect for skin treatments and other cosmetic uses, even on very sensitive skin.

As Viceral is a natural fibre, it is completely free from any binding agents for freedom from binder elution, retention of inter-filament bonds, and ultra-low fibril release in use with a broad range of solvents. Thanks to being natural, the material also benefits from the following properties:

• Viceral grade SB283 test results indicate it can absorb and hold about 13x its own weight in water
• It generates CO and CO2 during incineration, but virtually no harmful gases due to binder-free cellulose composition
• It minimizes static charge formation, due to moisture-retention properties inherent to its fibres
• It undergoes bio-degradation in soil and landfill disposal
• It can withstand temperatures up to 260ºC, free from the softening and decomposition characteristic of synthetic fabrics

For contact with the skin, especially as a spa component, Viceral is swiftly becoming the material of choice.
