This ingredient is biodegradable and non-toxic. This ingredient is commonly found in baby shampoos.

Decyl Glucoside is sometimes used to stabilize the UV filter Tinosorb.

Citric Acid

Buffering, Masking

Citric Acid is an AHA derived from citrus fruits (think oranges, lemons, and limes!).

As an AHA, Citric Acid removes the top layer of skin cells from the newer layer of skin underneath. This helps skin to remove dark spots and even out skin tone.

If you spot Citric Acid near the end of an ingredient list, it's likely there as a pH adjuster rather than an active ingredient.
