Vanishing cream : Cosmectic science notes

Vanishing cream : Cosmectic science notes

The formulation of vanishing cream follows certain principles and utilizes specific building blocks to achieve its desired characteristics. Vanishing creams are cosmetic preparations that are typically lightweight and designed to quickly absorb into the skin, leaving behind a smooth, non-greasy, and transparent or semi-transparent finish. Here are the principles of formulation and the building blocks commonly used in vanishing cream:

  1. Emulsification: Vanishing creams are typically oil-in-water (o/w) emulsions. The emulsification principle is essential to create a stable, uniform product. Emulsifiers, such as various types of surfactants, are used to facilitate the dispersion of oil droplets within the water phase, ensuring a homogeneous mixture.
  2. Base Ingredients:
  • Water: The water phase provides the main component of the cream and serves as a dispersion medium.
  • Oils or Lipids: Light oils or lipids are used in vanishing creams to provide emollient properties while being easily absorbed into the skin. Examples include mineral oil, cyclomethicone, dimethicone, and isopropyl myristate.
  • Humectants: Humectants like glycerin or propylene glycol are incorporated to attract and retain moisture, helping to hydrate the skin.
  • Thickeners: Thickeners, such as carbomer or cellulose derivatives, are used to provide the desired consistency and improve the stability of the cream.
  1. Active Ingredients: Vanishing creams may also contain active ingredients that provide specific benefits to the skin, such as moisturizing agents, antioxidants, vitamins, or other additives targeting skin conditions or desired effects.
  2. Fragrance and Preservatives: Fragrances are often added to provide a pleasant scent, while preservatives are included to prevent microbial growth and ensure product safety and shelf life.
  3. Stabilizers and Co-solvents: Stabilizers and co-solvents may be incorporated to enhance the stability of the emulsion and improve the compatibility of the ingredients. Examples include cetyl alcohol, stearic acid, or sorbitan stearate.
  4. pH Adjusters: pH adjusters, such as citric acid or sodium hydroxide, may be used to maintain the desired pH level for optimal skin compatibility.

The building blocks are carefully combined following appropriate formulation techniques, such as heating and mixing, to create a stable emulsion with the desired texture, spreadability, and absorption properties. The proportions of the ingredients and the specific manufacturing process may vary depending on the desired characteristics and the targeted skin types.

It’s worth noting that the specific formulation and building blocks of vanishing creams can vary among different products and manufacturers. It is essential to refer to the specific product formulation or consult with a cosmetic chemist for precise information on a particular vanishing cream.

Formulation:

While I can provide you with a general outline of a vanishing cream formula, it’s important to note that specific formulations may vary depending on the manufacturer, desired characteristics, and regulatory requirements. Here’s a basic formula for a vanishing cream:

Ingredients:

  • Water phase:
    • Distilled water: q.s. (quantity sufficient)
    • Glycerin: X%
    • Propylene glycol: X%
    • Preservatives: as required
    • pH adjuster (e.g., citric acid or sodium hydroxide): as required
  • Oil phase:
    • Light oils or lipids: X%
    • Emulsifier: X%
  • Active ingredients:
    • Desired active ingredients: X%
  • Thickeners:
    • Thickeners (e.g., carbomer or cellulose derivatives): X%
  • Stabilizers and co-solvents:
    • Stabilizers (e.g., cetyl alcohol, stearic acid, or sorbitan stearate): X%
  • Fragrance: as required

Instructions:

  1. In a separate container, combine the water phase ingredients (distilled water, glycerin, propylene glycol, preservatives, pH adjuster) and mix well until homogenous.
  2. In another container, combine the oil phase ingredients (light oils or lipids, emulsifier) and heat gently until the ingredients melt and blend together.
  3. Slowly add the water phase to the oil phase while stirring continuously.
  4. Continue stirring until the emulsion forms and cools down to room temperature.
  5. Add the active ingredients and mix thoroughly.
  6. Gradually add the thickeners while stirring to achieve the desired consistency. Adjust the amount as needed.
  7. Incorporate stabilizers and co-solvents while mixing well.
  8. Finally, add the fragrance and mix until evenly distributed.
  9. Perform pH testing and adjust if necessary by adding small amounts of the pH adjuster.
  10. Transfer the vanishing cream to suitable containers and label them appropriately.

It’s important to note that this is a basic formulation outline, and the percentages of the ingredients may vary depending on the specific product requirements and desired characteristics. Additionally, it is crucial to follow appropriate manufacturing practices, including hygiene, quality control, and stability testing, to ensure the safety and effectiveness of the final product.

Why vanishing cream are called as vanishing cream?

Vanishing cream is called so because of its unique property to seemingly disappear or “vanish” when applied to the skin. It is a type of cosmetic product that is designed to be easily absorbed into the skin without leaving any visible residue or greasy feeling. When you apply vanishing cream, it typically goes on as a creamy texture, but as you rub it into your skin, it appears to disappear, leaving behind a smooth and matte finish.
The term “vanishing cream” originated in the early 20th century when these types of cosmetic products became popular. The name was chosen to describe the cream’s ability to vanish upon application and leave the skin looking clean and natural. The idea was to create a product that would provide moisturization and other benefits to the skin without leaving any visible trace behind.
Over time, the term “vanishing cream” has become synonymous with this particular type of cosmetic product, which is designed to be lightweight, non-greasy, and quickly absorbed by the skin, resulting in a smooth, matte appearance.

What is disappear cream used for?

Disappearing cream is a type of cosmetic product that is primarily used in skincare routines. Its main purpose is to provide a light, non-greasy moisturizing effect while creating a smooth and matte appearance on the skin.

What is disappear cream made of?

Disappearing creams typically contain a combination of ingredients that contribute to their moisturizing, smoothing, and mattifying properties.

Latest Developments in Vanishing Creams:

  1. Multifunctional Formulations: Recent advancements focus on vanishing creams that serve multiple purposes beyond basic moisturization. Formulations are tailored to address concerns like acne, pigmentation, or uneven skin tone. Ingredients like niacinamide and salicylic acid are commonly included for their pore-minimizing, oil-controlling, and blemish-reducing properties.
  2. Advanced Active Ingredients: Manufacturers are integrating advanced active ingredients to enhance the efficacy of vanishing creams. Components like hyaluronic acid, peptides, and botanical extracts such as licorice root or green tea are being used to offer additional skin benefits like hydration, anti-aging effects, and antioxidant protection.
  3. Skin Type Specificity: Customized formulations are being developed to suit different skin types, such as oily, combination, or sensitive skin. Ingredients like aloe vera, chamomile, and soothing botanical extracts are included in formulations designed for sensitive skin, ensuring gentleness and minimizing potential irritations.
  4. Matte Finish and Oil Control: A major focus of recent vanishing creams is delivering a matte finish while effectively controlling excess oil. Innovations involve incorporating oil-absorbing ingredients like silica or kaolin clay, providing a smooth, non-greasy appearance without compromising hydration.
  5. Sustainability Initiatives: Similar to trends in other cosmetic products, there’s a growing emphasis on sustainability in vanishing creams. Brands are exploring eco-friendly packaging options, biodegradable materials, and responsibly sourced ingredients to align with environmentally conscious consumer preferences.
