Hydroxypropyl Methylcellulose (HPMC), also known as hypromellose, is a semi-synthetic polymer derived from cellulose. Thanks to its unique properties – water solubility, gel-forming ability, thermal stability, and biocompatibility – HPMC is widely used in several industries:
- Pharmaceutical
- Food
- Cosmetic
- Construction
HPMC in Cosmetics: Functions, Benefits and Applications
HPMC is widely used in the cosmetic and personal care industry due to its versatility and safety. It is odorless, non-toxic, biodegradable, and well tolerated by the skin – making it ideal for a broad range of formulations.
Main Functions of HPMC
Thickening agent
- Increases the viscosity of emulsions, gels, lotions, and shampoos. Enhances product texture and stability – effective even at low concentrations (0.1%–2%) and across a wide pH range.
Emulsion stabilizer
- Improves the physical stability of emulsions (oil-in-water or water-in-oil) by preventing phase separation and creating a stabilizing gel matrix.
Film-forming agent
- Forms a thin, transparent, non-occlusive film on skin or hair that retains moisture and protects against environmental aggressors. Commonly used in leave-on products like serums, face gels, masks, and primers.
Suspending agent
- Keeps insoluble particles (e.g., pigments, botanical extracts, microcapsules) evenly dispersed in liquid products such as toners, cleansing gels, or shampoos.
Conditioning agent
- In hair care, it improves combability, reduces frizz, and provides a soft, smooth feel.
Specific Cosmetic Applications
Facial Care
- Hydrating gels and light serums: improves viscosity without heaviness, silky finish.
- Peel-off masks: film-forming properties help create easy-to-remove layers.
- Face primers: smooth skin texture and extend makeup wear.
Body Care
- Lotions and body creams: stabilizes emulsions, enhances sensoriality.
- Gel or roll-on deodorants: used as a structuring agent.
Hair Care
- Shampoos and conditioners: stabilizes the formula, improves texture, adds conditioning effect.
- Hair gels: provides structure and light hold without stickiness.
Make-up
- Liquid foundations and BB creams: improves texture, promotes even application.
- Mascara: helps control viscosity and enhances adherence to lashes.
Formulation Benefits
- Compatibility with humectants (glycerin, panthenol), actives (niacinamide, vitamin C), and oils.
- Thermal stability: effective both cold and hot (up to 80–90 °C).
- Dermatological safety: non-irritant, non-comedogenic, suitable for sensitive skin.
HPMC has established itself as a key ingredient in modern cosmetics, thanks to its versatility, safety, and performance. Its ability to enhance the texture, stability, and sensorial profile of products makes it valuable not only in skincare treatments but also in cleansing and make-up formulations. In a market increasingly focused on effective and skin-friendly ingredients, HPMC offers a technical and natural solution that meets even the most complex formulation challenges.
