Tin Oxide \ Ci 778161\ ●
TL;DR. This ingredient is used mainly as an opacifier and colorant support, especially to add opacity, brightness, and soft-focus effects in makeup, sunscreens, and pearlescent pigment blends.
What does Tin Oxide \ Ci 778161\ do in a cosmetic formula?
This ingredient is used mainly as an opacifier and colorant support, especially to add opacity, brightness, and soft-focus effects in makeup, sunscreens, and pearlescent pigment blends.
Is Tin Oxide \ Ci 778161\ clean?
It has a low irritation profile because it is insoluble and largely inert on skin. Clean standards generally treat it as unproblematic when cosmetic-grade purity limits for trace metals are met.
Is Tin Oxide \ Ci 778161\ sustainable?
This material is mineral-derived and not biodegradable in the way plant-based organics are, but it is also not a persistent organic pollutant. The main sustainability considerations are mining impacts, energy use in refining, and trace-metal quality control.
Is Tin Oxide \ Ci 778161\ COSMOS-approved?
It is generally permitted under COSMOS-natural and COSMOS-organic as an allowed mineral colorant or opacifying material when it meets purity requirements. Its Green Chemistry fit is moderate to good, with strong stability and low skin reactivity, balanced by nonrenewable mineral sourcing and limited biodegradability relevance.
How does Tin Oxide \ Ci 778161\ work chemically?
The molecule is an insoluble inorganic metal oxide with a crystalline lattice, valued for high refractive index, opacity, and light-scattering behavior. It is stable to heat, light, and normal cosmetic pH ranges, and is commonly used as a coating or minor component in effect pigments rather than as a primary bulk powder.
