Regulators usually are part of the car's alternator, although many cars, particularly older cars and modern American models, have exterior voltage regulators. Alternators or generators are used to generate power, which is fed into the car's battery to maintain a full charge.
Titanium dioxide as used in sunscreens is commonly modified with other ingredients to ensure efficacy and stability. Examples of what are known as surface modifier ingredients used for titanium dioxide include stearic acid, isostearic acid, polyhydroxystearic acid, and dimethicone/methicone copolymer.
1 About Titanium Dioxide What is titanium dioxide? ï· Titanium dioxide (TiO 2) is a white solid inorganic substance that is thermally stable, non-flammable, poorly soluble, and not classified as hazardous according to the United Nationsâ (UN) Globally Harmonized System of Classification and Labeling of Chemicals (GHS). Based on existing safety information, it can be concluded that the use of titanium dioxide nanomaterial (ultrafine) as an ingredient in cosmetic sunscreen products at a concentration up to 25 % poses no risks to human health (12, 13).
