Sodium Hydroxide. May Contain Red 33/Ci 17200 ●
TL;DR. This ingredient is used mainly as a pH adjuster, raising formula pH or neutralizing acidic ingredients. In soaps and some hair products, it can also support saponification or polymer neutralization.
What does Sodium Hydroxide. May Contain Red 33/Ci 17200 do in a cosmetic formula?
This ingredient is used mainly as a pH adjuster, raising formula pH or neutralizing acidic ingredients. In soaps and some hair products, it can also support saponification or polymer neutralization.
Is Sodium Hydroxide. May Contain Red 33/Ci 17200 clean?
From a clean-beauty perspective, it is generally accepted when used at low levels and when the finished product has an appropriate pH. The concentrated raw material is highly irritating, so evaluation depends more on final formula pH than on its presence alone.
Is Sodium Hydroxide. May Contain Red 33/Ci 17200 sustainable?
This material is typically made from salt brine through electrolysis, which can be energy intensive but uses abundant mineral inputs. It is inorganic and does not biodegrade in the usual sense, but it dissociates and is neutralized rather than persisting as an organic pollutant.
Is Sodium Hydroxide. May Contain Red 33/Ci 17200 COSMOS-approved?
It is permitted under COSMOS for allowed technical functions such as pH adjustment and soap making. Its Green Chemistry profile is mixed, with simple mineral feedstocks and no organic persistence, but energy use in manufacture is a consideration.
How does Sodium Hydroxide. May Contain Red 33/Ci 17200 work chemically?
The molecule is a small inorganic ionic compound that dissociates fully in water, making it a strong pH-raising agent. Typical use is often below 1% in finished formulas, added as a dilute solution and controlled by pH targets, since excess can destabilize emulsions, thickeners, or skin-compatible acidity.
