2. VANISHING CREAM Definition: Vanishing Creams: They are oil in water type of emulsions. When applied on the surface of skin, they spread as thin oil less film which is not visible to the naked eye. Hence, they are called as vanishing creams. They are used to hold powder on the skin as well as to improve adhesion.

3. Advantages It is used as a  skin moisturizer , skin cleanser. Softens the skin and provides a shiny texture to the skin. Used as a base on the skin before any other cosmetic application because it  vanishes from the skin  surface once applied. Used to blemish any pimples or scars. Prevents skin  chapping  or roughening. VANISHING CREAM

4. Disadvantages Skin allergies due to certain compounds in the cream. Skin reactions like  itching, peeling, irritation, reddening  etc might happen. These products have stability issues and hence should be stored at prescribed conditions.       VANISHING CREAM

5. Neutral or pleasant odor and color Easy to spread, pleasant feeling during application Easy penetration Non-oily/ non-greasy after application Non comedogenic Well tolerance/ non-allergenic Bring hydration IDEAL PROPERTIES OF VANISHING CREAM

6. COMMON INGREDIENTS IN VANISHING CREAM Stearic acid It governs the consistency of the cream and imparts pearlescent property to the cream by forming crystals. Humectants Example: glycerin, sorbitol , Propylene glycol These help to keep skin moistened, wet, feels cool and gives emollient effect too.

7. COMMON INGREDIENTS IN VANISHING CREAM Alkalies Example: Potassium hydroxide: It imparts fine texture and consistency without providing harshness. Sodium hydroxide: It is used in combination with potassium hydroxide because it forms hard cream, when used alone. Carbonates i.e., potassium and sodium carbonate: They are widely used, because they liberate carbon dioxide due to this, creams become spongy.

8. COMMON INGREDIENTS IN VANISHING CREAM Ammonia: It is effective, but difficult to handle because of odour and volatility. it is also makes cream yellow in color with age. Borax: It is used in combination with potassium hydroxide to produce a white emulsion.

9. COMMON INGREDIENTS IN VANISHING CREAM Emulsifying agent It causes emulsification of the two phases i.e. oil and aqueous phase. Helps stabilize the preparation and enhancing uniformity of added ingredients. Example: triethanolamine soap, Amino glycol soap or Glyceryl monostearate Purified water (i.e., distilled and deionized ) It provides stability to the cream. If hard water is used, it leads to the formation of soaps of lime and magnesium, which causes inversion of emulsion and hence stability is reduced

10. COMMON INGREDIENTS IN VANISHING CREAM Preservatives They prevent deterioration cause by bacteria or fungi. Long term preservation of the product is an important aspect in economical point of use, as well for improved shelf life is concerned. Example: methyl paraben and propyl paraben Perfume i.e., perfume solvent or perfume is dissolved in alcohol. They should be added when the cream attains a temperature of about 40°c. Example: geranium, sandal wood, lavender oil, terpineol etc. It provides odour to the cream and also has aesthetic value.

11. PROTOTYPE FORMULATION OF VANISHING CREAM Phase Ingredients Quantity (%) A Stearic Acid 12.5 Cetyl alcohol 1.0 Glycerol 6.0 Potassium hydroxide 1.0 B Propyl Paraben 0.025 Methyl Paraben 0.05 Rose oil q.s . Purified water 29.34

12. Steps carried out in the preparation of vanishing cream are as follows: Preparation of oil phase The oil soluble ingredient such as Stearic acid, potassium hydroxide, and sodium carbonate are taken int oone porcelain dish and this mixture is melted at 70 O C. Preparation of aqueous phase The aqueous soluble ingredients as in different formulae e.g. glycerin, parabens , other extracts if any are taken into another porcelain dish and heated this mixture at 70 O C. FORMULATION OF VANISHING CREAM

13. Addition of oil phase to aqueous phase The oil phase is added to the aqueous phase with continuous stirring at 70 O C. Now, once the transfer is completed, it is allowed to come at room temperature, all the while being stirred. Perfume is then added at last just before the finished product transferred to suitable container. FORMULATION OF VANISHING CREAM

14. Determination of organoleptic properties The appearance of the cream is judged by its color, pearlscence and roughness and graded accordingly. The organoleptic features are very important concerned to user’s compliance and marketability. Determination of pH Accurately weighed 5 g of the sample of preparation is dispersed in 45 ml. of water. The pH of the suspension is determined at 27°C using digital pH meter. The value should comply to the specified pharmacopoeia limits. pH has a definite role to perform as far the skin friendliness and biological compatibility of this vanishing cream application is concerned. EVALUATION OF VANISHING CREAMS

15. Spreadability The spreading characteristic of the preparation is tested and observed for good spreadability which is very much desired characteristic of a good product. Determination of homogeneity The formulations are tested for the homogeneity by visual appearance and by touch. The high level of homogeneity is desired often to pass the preparation. Rheological studies Vanishing cream preparation is tested for rheological parameters and is concluded for fluidity. This also has correlation to physical integrity of the product and its spreadability parameter. EVALUATION OF VANISHING CREAMS

16. Determination of wetness It is determined by applying cream on skin surface of human volunteer. The wetly feel gives the test conclusion. Determination of type of smear It is determined by applying the cream on the skin surface of human volunteer. After application of cream, the type of film or smear formed on the skin is checked. A good long-lasting smear or film forming characteristic is desired. Determination of emolliency Emolliency , slipperiness and amount of residue left after the application of fixed amounts of cream is checked. All parameters have a definite role in view of product efficacy and acceptance by the users. EVALUATION OF VANISHING CREAMS

17. Sheen Effect:  One characteristic due to which these vanishing creams are preferred is the ‘sheen effect’. Rather than giving a caked look to the face, they give a natural attractive sheen to the skin. Daily day creams:  Vanishing Creams has the advantage of being non-greasy which makes them suitable for use during the day and by women with oily skin. In addition to keeping powder on the face, they also protect the skin from the elements such as ‘chapping winds’ and dry breezes. The presence of a humectant that they contain helps reduce moisture loss from dry skin. As vanishing creams have a semi-matt finish, they can also be used without powder to reduce the effects of oiliness and shine on skin. APPLICATION OF VANISHING CREAMS

18. Moisture locking power:  The magical quality of vanishing cream that makes it a choice as daily cream is the moisture locking power. As many women know that moisture is the key element of a healthy skin, the mystical power of vanishing cream still eludes some women. It is equally effective for normal and oily skin types. An airy, non-sticky, fluffed up emulsion, the cream is not at all greasy and protect your skin’s natural moisture. APPLICATION OF VANISHING CREAMS
