Nanomaterials are substances used to improve UV protection and product texture in skincare products including sunscreens, creams, lotions, anti-aging products and serums. But, their use has raised concerns about potential safety and health risks, which has led to strict regulations and safety assessments to ensure they do not pose health risks to consumers.
The INCI code for nanomaterials is not a single code but rather a system used to name and classify ingredients used in cosmetics like nanomaterials. If a nanomaterial is present in a cosmetic product, it should be identified as a nanomaterial by placing the word "nano" in front of the INCI name. For example, if the INCI name for a specific nanomaterial is "Titanium Dioxide," and it's used in nanoscale form, it would be listed as "Nano Titanium Dioxide" on the product label.
Nanomaterials can be created through various methods in laboratories or extracted from natural sources, depending on the specific material and its intended application.
The tolerance of nanomaterials on skin depends on the specific material and formulation, so some may be well-tolerated while others may cause skin irritation. Careful testing and evaluation in cosmetic and skincare products is needed.
Improves Sun Protection
Nanoparticles of ingredients like zinc oxide and titanium dioxide in sunscreens provide effective UV protection with a more transparent and lightweight application.
Reduces White Effect
In sunscreens, nanoparticles help reduce the undesirable white cast often associated with mineral-based UV filters.
Improves Ingredient Penetration
Nanotechnology can enable better delivery of active ingredients into skin to improve product effectiveness.
Smoothes Product Texture
Nanoparticles can improve product texture and make creams and lotions feel smoother and more pleasant during application.
Extends Shelf Life
Nanoparticles can improve product stability and prevent ingredient degradation, which helps to extend the product shelf life.
