#1Cyclopentasiloxane

Origin: chemical
Role: Skin conditioning agent, Emollient, Hair conditioning, Solvent
Protection
Silicones
EWG Rating [ 3 ]
CIR Rating [ A ]

Cyclopentasiloxane is a fluid silicone. It’s non-greasy and doesn’t have any scent or color. It evaporates pretty fast which makes this ingredient essential when it comes to making products that have to dry quickly. It also gives a nice silky feeling when you apply the product to the skin and hair. It leaves a thin film that protects the skin after evaporation.

Cyclopentasiloxane is chemically neutral, meaning it doesn’t react with other components.

Position 2

#2Squalane

Origin: natural
Role: Skin conditioning agent, Emollient, Hair conditioning
Softening
Comedogenic rating [ 1 ]
EWG Rating [ 1 ]
CIR Rating [ A ]

Squalane is a more stable equivalent of Squalene. It is a very important component of our skin. It’s a major part of natural sebum that forms a protection barrier on the skin's surface. If the barrier isn’t strong enough, your skin will become more sensitive. Squalane helps to keep skin hydrated, protects it from the negative impact of the environment, lowers irritation, stimulates regeneration, and removes dryness. It is accepted by our skin very well and will not cause allergic reactions.

Avocado oil is a natural ingredient with an excellent rejuvenating and moisturizing effect. It's so effective because it contains a lot of squalene - a very strong chemical that protects the skin and helps to keep it hydrated. It's also a nice antioxidant that helps to slower aging. Avocado oil also contains different vitamins (A, B, E), lecithin, and beta-carotene.

Helianthus Annuus (Sunflower) Oil is an ingredient known from ancient times. It’s the oil people receive from Sunflower Seeds and use for different purposes, including cooking. It contains a lot of Lenoic acid which moisturizes the skin, makes it softer, and reduces inflammation. The oil also works as an occlusive agent that forms a protective film and helps to keep skin hydrated.

As for haircare, it’s the second most popular basic oil used in haircare products. It helps to lower hair fragility and make hair softer.
