Answer: superficial
4 Traditional intended benefits of cosmetic products:
improvement of:
1. scaling
2. skin color
3. wrinkles (fine and coarse)

is generally defined as an alkali salt of a long-chain fatty acid. When a fat or oil is saponified, the sodium or potassium salt
formed from the long-chain fatty acids.

Soap cleans by altering the surface tension of
water and emulsifying and suspending soils to
be rinsed away.

Which of the following accurately describes what happens when soap molecules encounter oil or grease?
A) The oil or grease is broken down into smaller molecules by the soap.
B) The soap molecules form a barrier around the oil or grease, preventing it from interacting with water.
C) The soap molecules coat the oil or grease, forming clusters called micelles.
D) The soap molecules repel the oil or grease, causing it to separate from water.
Answer: C) The soap molecules coat the oil or grease, forming clusters called micelles.
This are soap’s raw materials?
FATS AND OILS
naturally occurring fats and oils used in soap making with three fatty acid groups randomly esterified with glycerol (trihydroxy alcohol)

Hydrolyzed (split)
Which of the following is the purpose of distillation in the process of producing soap from fatty acids?
A) To mix the fatty acids with water and alkali
B) To filter out impurities from the fatty acids
C) To separate the fatty acids from other compounds
D) To heat the fatty acids and alkali mixture
Answer: C) To separate the fatty acids from other compounds.
The principal animal fat in soap making is obtained from the meat processing industry as a result of rendering body fat from beef and in some cases sheep.
PALM OIL
TALLOW
PALM STEARIN
COCONUT OIL
PALM KERNEL OIL
TALLOW
one of the most important vegetable oils used in soap making. Composed mostly of C12 (lauric, 48%) and C14 (myristic, 18%) fatty acids, reducing hardness and providing solubility and lather with large bubbles that do not last long.
PALM OIL
TALLOW
PALM STEARIN
COCONUT OIL
PALM KERNEL OIL
COCONUT OIL
Often serves as a substitute for tallow, it is obtained from the fruit of the palm tree. Composed of mostly long chain-length fatty acids-such as C16 (palmitic, 44%) and C18:1 (oleic, 41%)-providing properties and compositions more similar to tallow than other vegetable oils.
PALM OIL
TALLOW
PALM STEARIN
COCONUT OIL
PALM KERNEL OIL
PALM OIL
Obtained from the center of the nuts of the palm tree and is
composed of mostly shorter chain-length fatty acids-such as C12 (lauric, 50%) and C14 (myristic, 16%)-providing properties and composition similar to coconut oil. And commonly used as a substitute to coconut oil in the soap making process.
PALM OIL
TALLOW
PALM STEARIN
COCONUT OIL
PALM KERNEL OIL
PALM KERNEL OIL
composed of mostly long chain- length fatty acids but with lower degree of saturation. It is produced by splitting palm oil
into palm olein (which is used in foods) and palm stearin. It provides properties more similar to tallow than other vegetable oils.

SKIN ADDITIVES used in soap:
GAFFPOSS ABAFE
A. Fragrance
B. Free Fatty Acid or Superfatting
C. Glycerin
D. Preservatives
E. Skin conditioners
F. Antimicrobial agent
G. Synthetic surfactants
H. Others:
● binders (gums and resins)
● Fillers (dextrin, salt, talc, etc.)
● Exfoliants,
● Anti-acne actives,
● Anti-irritants.
neutral fats and oils are first upgraded to remove particulate
dirt, proteinaceous materials, and other odor and color bodies, and then reacted with caustic (NaOH or KOH) yielding neat soap and free glycerin.
Neutral Fat/Oil Route or Saponification
Fat splitting/Fatty acid route
Neutral Fat/Oil Route or Saponification

Neutral Fat/Oil Route or Saponification
Fat splitting/Fatty acid route
Neutral Fat/Oil Route or Saponification
the fats and oils (triglycerides) are hydrolyzed with
high-pressure steam (fat splitting) to produce
fatty acids and glycerin. The fatty acids are then purified by distillation and neutralized with an alkali to produce soap
(neat soap) and water. This method of production is most suitable when lower grade fats and oils are used for
soap production.
