1 Colloids and SurfacePhenomena Aspects Of Make Up and Lipstick. Group Members CHAIN, KOK KEONG LE, DIEUHANH THI MCLAUGHLIN, KELLY E VAN NATTER, RAINEE M Date: 18 th April 2002

2 Introduction Definition of Cosmetic Ingredients Overview of Customer Requirements Role by Polymer and Surfactants Application in Cosmetic Products: –Eye shadow and Blush –Lipstick –Liquid Cream –Pressed Powder for both pale and dark skin

3 Overview of Cosmetic Consumer aspect –High quality –Safe or non allergic –Reasonable Price –Multiple Performance –Long Wearing

4 Role by Polymer And Surfactant Polymer –gel like, long chain carbon with cross-linked conformation Encapsulation Firm distribution High internal surface areas, ideal sorption and desorption mechanism Surfactant –hydrophilic head group + hydrophobic tail Emollients, wetting agents, and emulsifying agents,humectants To promote lubricant, adhesiveness, slip and covering purposes

5 What are pressed powder properties? Slip –Spread Easily, smooth feeling –Rhapsody, Zinc Stearate Adhesiveness –Cling Together –Zinc Stearate, Octyl Palmitate Other Ingredients –Coloring Pigments, Iron Oxide –Shininess Appearance –Not over darkness and chalkiness

6 Pressed Powder for both pale and dark skin

7 Action and Mechanism Zinc Stearate –Zn (C 18 H 35 O 2 ) 2, –long hydrocarbon chain – ideal physicals < 6% of moisture, alkaline, soluble in mineral oils –promoting the powder flow ability –reduced the interfacial tension Octyl Palmitate –as liquid binder, –provide cohesion –as emulsifier, emollients Iron Oxide –(Fe 2 O 3 ), Color Pigment

8 How to Produce make up? Guidelines by Ultra. Chemical Inc. –pulverize or to crush Rhapsody talc in to powder form –compress them into pan utilizing (200psi – 2000psi )

9 Lipsticks Purpose: –Protect lips from hard weather –Color lips Objectives: –Variation in color from application to application –Lasts all day –Removable with cleansers Basic categories of lipsticks: –Matte: heavy in wax and pigment but lighter in emollients. –Gloss : less wax and more oil to make the lips shinier. –Long lasting: contains silicone oil, which seals the color the lips. –Satin: combination of gloss and matte lipsticks. –Frosted: include a pearl zing agent that adds luster to the color.

10 Lipsticks Example of Lipsticks, Matte Formulation composition* Components Range % by wtPreferred by wt 1.Candellela Wax Ozokerite Paraffin wax Isosteryl Isostearated Ultrapure HMP-S Capric/Caprylic Triglyceride Castor OilQS Propyl Paraben Tocopheryl Acetate Colorants: D&C #7 CA lake Red Oxide Rhapsody Talc 4M Total *Ultra Chemical Inc.

11 Lipsticks Function of Ingredients 1.Emollients a. Castor oil: -extracted from castor plant b. Capric/Caprylic Triglyceride: -oily liquid extract from plant vegetable oil and dairy fats. c. Isostearyl Isostearate 2.Emulsifiers a. Paraffin Wax: -derived from petroleum b. Ozokerite Wax: -ceresin wax, naturally occurs in mineral wax. 3.Preservatives a. Propyl Parahen: -propyl-4-hydroxylbenzoate and prepare from p- bromophenol 4.Colorants a. D&C Red #7 CA lake: b. Red Oxide c. Ultrapure HMP-S 5.Binders a. Candellia wax

12 Lipsticks Processing 1. Heat the ingredients to 75-85degree Celsius 2. Mix until the batch is smooth and uniform

13 Lipstick Shapes, packaging and price *There are different shapes and packaging of lipsticks. The prices are ranging from $1.99 to $29.99, depending to the Brand name of product, such as Lancôme, Avon, L’Oreal, etc.

14 Eyeshadow & Rouge Purpose: –To provide color Requirements & Objectives: –Contain pigments –Adhere to skin –Have adequate “slip” to spread onto skin –Limited solubility in perspiration (to avoid streaking), but easily removable with cleansers –Safe for eyes (preservatives) ~40 sec

15 Forms Liquid suspension/ emulsion Solid, stick (L’Oreal) (Wet N Wild) Dry, Compact (Almay, Inc.) (Black Opal/ BioCosmetic Research Labs ) Solid, creamy ~25 sec

16 Rouge/Eyeshadow Ingredients Filler Pigments and Opacifiers Binders Emulsifiers Emollients Preservatives Absorbents Perfume Carriers Viscosity controllers/thickeners (Brief Overview Slide)

17 Main Ingredients Dry, Compact Cosmetics: –Talc ( 3MgO·4SiO 2 ·H 2 O ) (Filler) –“Slip” and shine due to lamellar structure –Very soft –White –Adheres to skin evenly Liquid/Gel Rouges: –Water (Solvent) Cream/Solid Cosmetics: –Caprylic/capric triglyceride (Solvent & Emollient) –Octyl Palmitate (Binder & Emollient) –Mineral Oil (Binder) –Castor Oil (see “Lipsticks”) ( Marmion, Sagarin ) Talc already discussed (kkc) - don’t describe in detail Below: esters and oils Talc already discussed (kkc) - don’t describe in detail Below: esters and oils

18 Pigments & Opacifiers Purpose: –To provide the color for the cosmetic –Opacifiers increase the opaqueness (coverage) of the applied cosmetic color Objectives: –Should not change color, bleed, or streak with pH changes, water, or oil (perspiration) –Should not fade significantly when exposed to light –Be heat stable –Be easy to add into product –Be non-toxic –All pigments of same particle size ~15 sec (Sagarin , Poucher III 283)

20 Binders, Emulsifying Agents, Surfactants, and Emollients Binders: –Provide cohesion of powders Emulsifying Agents/Surfactants –Promote the mixing of otherwise immiscible liquids –Lower surface tension, promoting more even mixing Emollients –Soften and smooth the skin ***Many cosmetic ingredients serve more than 1 of these purposes, and thus they have been combined for the purpose of listing ingredients.
