Cosmetic Product Formulation I SS2 Beauty & Cosmetology Lesson Note

Why “Natural” is Trending

Before we start mixing, we need to understand why people are moving away from factory-made products.

• The Skin is a Sponge: Whatever we rub on our skin can be absorbed into our bodies. Natural cosmetics use ingredients you can often eat (like honey, coconut oil, or sugar), making them safer for long-term use.
• Eco-Friendly: Natural products don’t use “microplastics” that hurt the ocean.
• Cost-Effective: You can often find your ingredients in the local market or even your backyard (like Aloe Vera or Shea Butter).

Teacher’s Note: “Natural” doesn’t mean “weak.” Nature is powerful! Think of how lime juice can brighten a stain; that same power can be used for the skin.

The Magic of Oils and Butters (The Base)

Every natural product needs a “base.” This is the ingredient that carries the vitamins and moisture to the skin.

• Carrier Oils: These are liquid oils like Coconut Oil, Almond Oil, or Jojoba. They sink into the skin quickly.
• Natural Butters: These are solid at room temperature.
  1. Shea Butter (Ori): Excellent for healing scars and deep moisturizing.
  2. Cocoa Butter: Great for skin elasticity and smells like chocolate!
• Essential Oils: These are the “scent” and the “medicine.” Examples include Lavender (for relaxation) or Tea Tree (for fighting pimples). Warning: Never use these directly on the skin without mixing them into a carrier oil first!

Exfoliants (The Natural Scrubs)

Our skin is constantly renewing itself. A scrub helps “brush away” dead skin cells so the fresh, glowing skin underneath can show.

• The “Scratch” Factor: * Sugar: Soft and melts quickly. Good for the face and lips.
  1. Salt: Rougher and detoxifying. Best for feet and elbows.
  2. Coffee Grounds: Great for “waking up” the skin and reducing puffiness.
• The Recipe: A basic scrub is usually 2 parts exfoliant (sugar/salt) to 1 part oil (coconut/olive).

Practical Tip: When making scrubs, never let water get into the jar. Since we aren’t using chemical preservatives, water will make the scrub grow mold!

Cold-Process Soap Making (The Basics)

Soap making is a chemical reaction called Saponification. This is when an oil meets an “alkali” (Lye) and they turn into soap.

• The Ingredients: 1. Oil: (Palm oil, Coconut oil, or Shea butter). 2. Lye (Sodium Hydroxide): The “activator.” 3. Water: To dissolve the lye.
• The Safety Rule: Lye is dangerous before it becomes soap. You must wear gloves and goggles. Always pour the Lye into the Water, never the other way around (remember: “The Snow falls on the Lake”).

Packaging and “Shelf Life”

Because our products are natural, they don’t last forever like the ones in the supermarket.

• Sterilization: Always wash your jars with hot water and dry them completely before filling them.
• Vitamin E: Adding a few drops of Vitamin E oil doesn’t just help the skin; it acts as a natural antioxidant to keep the oils from going “rancid” (smelling bad).
• Labelling: Every product must have:
  1. The name of the product.
  2. All ingredients used.
  3. The “Made On” date.

Classroom Practical & Discussion

1. Sensory Test: Smell and feel the difference between Shea Butter and Coconut Oil. Which one feels “heavier”?
2. The Mix: Create a simple “Hand Scrub” using brown sugar and any oil available in the lab.

Safety Quiz: Why do we wear goggles when working with Lye?
