added in small amounts to add consumer acceptance and to make the product more marketable. ex. Adding fragrance, adding vibrant colors.

added extra

these are used to remove skin cells or plaque from teeth through friction

they reduce oxidation and rancidity from occuring over time.

antioxidants

they are also known as sequestrants.

chelating agents

they act as supportive ingredients to lengten the shelf life of the product

antioxidants

marketed as skin nurturers

antioxidants

help improve the product's stability by binding metal ions that may be present in raw materials

chelating agents

they are essential in foaming products as they bind ions in hard water and prevent deterioration of the foam.

chelating agents

used to give color to the product or the skin.

colorants

They induce a tightening and toning effect on the skin.

cosmetic astringents

It stabilizes the emulsion once formed and prevents the separation of oil and water in the emulsion and used as thickening agent.

Emulsion stabilizer

They remove dead skin cell layers by dissolving intracellular "cement" holding surface skin cells together.

exfoliants

They are usually found in skin whitening or skin peel products in the presence of low pH.

Exfoliants

This is used to enhance the products' smell or to mask undesirable odors/scents.

fragrance

These are used to condition and improve the hair's appearance, gloss, and shine while facilitating styling and reducing the static of the hair.

Opacifying agents

They adjust the pH of the product at the desired range.They can be considered as Acids (lower the pH) and bases (raise the pH).

pH adjusters

They prevent or retard microbial growth in cosmetics.

preservatives

a type of skin conditioning agent that imparts softness to the skin by remaining on the upper layer of the skin and reducing flaking

Emollients

type of skin conditioning agents that retard moisture loss by holding water within the surface layers of the skin and drawing in moisture from the air

These thicken the water-soluble components of the product.

viscosity increasing agents (aqueous)

These thicken the oil-soluble components of the product.

viscosity increasing agents (non-aqueous)

can flow freely.

Liquid

thicker than liquid and have limited flow properties(high viscosity)

gel

has limited flow capacity and prevents the product from running out of the hand since it foams up.

Foaming gel

made up of smaller molecules that can penetrate deeply into the skin and deliver a high concentration of active ingredients

Serum

contains low viscosity emulsions

Lotion

A type of binder between oil and water
