And here are the study notes for the text:
Cosmetic Creams
- Cosmetic creams are emulsified products.
Classification of Creams
- Creams can be classified according to their function: cleansing, foundation, hand, night, or all purposes creams.
- Creams can be physically described as liquid or semisolid, with descriptive adjectives like soft, firm, thick, or thin.
Emulsion Type
- Creams can be classified into oil-in-water (o/w) or water-in-oil (w/o) emulsions.
pH Measurement
- pH measurement for o/w creams: use a pH meter directly.
- pH measurement for w/o creams: dissolve in aqueous alcohol (50%) and use a pH meter.
Slip Melting Point
- The slip melting point of the oil phase is measured using the capillary tube method.
Ingredients and Claims
- Named ingredients and special claims can be obtained from the label.
