Both equally Ascorbyl Tetraisopalmitate and Ethyl Ascorbic Acid are common derivatives of Vitamin C Employed in skincare formulations, but they have distinct Qualities that make them acceptable for various pores and skin concerns and formulations.
1. Ascorbyl Tetraisopalmitate:
Solubility: Oil-soluble
Balance: Very steady; less vulnerable to oxidation compared to pure Vitamin C
Penetration: Its oil-soluble nature enables it to penetrate deeper into the pores and skin, achieving the lipid layer for Improved performance.
Key Benefits:
Potent antioxidant motion
Stimulates collagen generation
Lowers hyperpigmentation and evens skin tone
Offers anti-getting older benefits by smoothing fine strains and wrinkles
A lot less annoying plus much more suited to sensitive pores and skin forms
Utilization: Typical in anti-getting older and brightening serums, creams, and sunscreens.
two. Ethyl Ascorbic Acid:
Solubility: Drinking water-soluble
Stability: Reasonably stable in comparison to pure ascorbic acid; extra steady than L-ascorbic acid but less steady than Ascorbyl Tetraisopalmitate.
Penetration: As being a h2o-soluble kind, it really works properly in hydrophilic environments and is helpful while in the upper levels from the pores and skin.
Principal Positive aspects:
Robust brightening effects by inhibiting melanin generation
Efficient antioxidant that shields towards absolutely free radicals
Supports collagen synthesis, marketing firmness and elasticity
Lightens darkish Ascorbyl Tetraisopalmitate places and improves skin tone
Utilization: Often present in brightening serums, light-weight formulations, and h2o-based mostly solutions.
Important Discrepancies:
Solubility: Ascorbyl Tetraisopalmitate is oil-soluble, rendering it ideal for oil-based mostly formulation and further pores and skin penetration, Whilst Ethyl Ascorbic Acid is h2o-soluble, perfect for lightweight, water-based mostly merchandise.
Steadiness: Ascorbyl Tetraisopalmitate tends to be much more stable, particularly in very long-time period formulations, whilst Ethyl Ascorbic Acid is more stable than pure Vitamin C but can nevertheless degrade after a while.
Pores and skin Sensitivity: Ascorbyl Tetraisopalmitate is mostly gentler and not as likely to bring about discomfort, when Ethyl Ascorbic Acid is well suited for lots of pores and skin forms but may be slightly much more irritating for extremely delicate pores and skin.
Summary:
Equally Ascorbyl Tetraisopalmitate and Ethyl Ascorbic Acid offer you exceptional Added benefits as Vitamin C derivatives, but These are preferred based upon formulation desires. Ascorbyl Tetraisopalmitate Ascorbyl Tetraisopalmitate is ideal for deeper penetration and oil-centered solutions, even though Ethyl Ascorbic Acid performs effectively in water-centered solutions by using a target brightening and antioxidant protection.
