INCI: Sorbitan Olivate - Also known as: Olivem 1000 (with Cetearyl Olivate), Sorbitol Olive Oil Ester

QUICK FACTS

What is Sorbitan Olivate?

Sorbitan Olivate is the second component of the Olivem 1000 emulsifier system, produced by esterifying olive oil fatty acids with sorbitol - a sugar alcohol derived from fruit. While Cetearyl Olivate provides the primary emulsification and lamellar structure-forming character of the system, Sorbitan Olivate contributes the hydrophilic counterpart that enables the two components to co-create the characteristic lamellar liquid crystal architecture that defines the Olivem system's skin interaction profile.

The chemistry of the pair reflects the HLB (hydrophilic-lipophilic balance) principle of emulsifier design: Cetearyl Olivate is relatively lipophilic, while Sorbitan Olivate's sorbitol head group adds sufficient hydrophilicity to create a balanced emulsifier pair that can organize oil and water phases into ordered lamellar structures rather than conventional globular droplet emulsions. The specific ratio in which the two are formulated is critical to the lamellar architecture - they are not interchangeable or independently effective and are always listed together in formulas where the Olivem system is used.

Sorbitan Olivate's sorbitol component also contributes mild hygroscopic character - sorbitol is a polyol with humectant properties that adds a subtle moisture-attracting dimension to the emulsifier's skin contact, contributing to the comfortable, hydrating application feel of both cream formulas.

What does it do for skin?

Sorbitan Olivate's contribution to skin is understood through its role within the Olivem 1000 system. As the hydrophilic partner to Cetearyl Olivate, it is essential to the formation of the lamellar liquid crystal emulsion structure that gives both cream formulas their distinctive skin-like application feel and their studied compatibility with the stratum corneum's own lipid architecture.

The lamellar structure that Sorbitan Olivate helps create is associated in research with improved active delivery at the skin interface - because the ordered lipid layers of a lamellar crystal emulsion can interact more intimately with the skin's own lamellar barrier structure than a globular emulsion. This is studied in connection with more efficient deposition of the emulsion's active payload at the skin surface, which is particularly relevant in formulas where 40-46% of the formula by weight consists of skin-targeted actives.

Sorbitan Olivate's sorbitol moiety also contributes a mild skin-conditioning and smoothing dimension at the point of application - the sorbitol's hygroscopic character adds to the initial moisturizing skin feel that characterizes the Hydra-Cream's cushioned satin finish and the Lipid-Cream's emollient radiant finish.

FOUND IN

In 2 Formulas - Always Paired with Cetearyl Olivate

Sorbitan Olivate functions exclusively as part of the Olivem 1000 system alongside Cetearyl Olivate. The two are always formulated together and are listed consecutively in the ingredient lists of both Sweet Chemistry cream formulas.

Hydration - Dry to Normal

Elasticity Reinforcing Hydra-Cream Cetearyl Olivate + Sorbitan Olivate (above 1%) - 1.7 oz / 50 ml

The Olivem system creates the lamellar liquid crystal architecture of the Hydra-Cream's 40%-active emulsion - the structural foundation that enables stable co-delivery of 3% Matrikynes® peptides, 2% THD ascorbate, the full ceramide barrier complex, and the complete NMF system in a cushioned satin finish.

Hydration - Dry to Dehydrated

Elasticity Reinforcing Lipid-Cream Cetearyl Olivate + Sorbitan Olivate (above 1%) - 1.7 oz / 50 ml

In the Lipid-Cream, Sorbitan Olivate co-creates the lamellar emulsion structure that carries 3% Matrikynes® peptides, 2% THD ascorbate, shea butter, the full botanical seed oil panel, and the ceramide barrier complex in the highest-active-concentration cream in the Sweet Chemistry range.

WORKS TOGETHER WITH

Olivem Partner Cetearyl Olivate

INCI: Cetearyl Olivate.

The lipophilic primary emulsifier in the Olivem 1000 system, always formulated alongside Sorbitan Olivate in both Sweet Chemistry cream formulas. Synergy Note: Cetearyl Olivate and Sorbitan Olivate are two halves of a single emulsifier system - the hydrophilic Sorbitan Olivate completes the HLB balance needed for Cetearyl Olivate to form lamellar crystal structures. Neither produces the lamellar architecture independently.

Rheology System Carbomer + Xanthan Gum + Polyvinyl Alcohol

INCI: Carbomer, Xanthan Gum, Polyvinyl Alcohol.

The polymer network that reinforces and gives viscosity to the Olivem lamellar emulsion in both cream formulas. Synergy Note: The Olivem system provides the lamellar structural foundation; the polymer network provides viscosity and application consistency. The combination creates both the structural elegance and the practical usability of the Sweet Chemistry cream textures.

Co-Emulsifiers Sodium Lauroyl Lactylate + Sodium Stearoyl Glutamate

INCI: Sodium Lauroyl Lactylate, Sodium Stearoyl Glutamate.

Supporting emulsifiers in both creams that complement the primary Olivem system. Synergy Note: The secondary emulsifier system reinforces the Olivem architecture at lower concentrations, contributing additional emulsion stability and broad-spectrum emulsification coverage alongside the primary Sorbitan Olivate / Cetearyl Olivate pair.

ECM Peptide Complex Matrikynes® Bone Peptides

INCI: Hydrolyzed Cow Bone Extract.

At 3% in all four formulas. Synergy Note: The Olivem lamellar system - to which Sorbitan Olivate is essential - provides the structural architecture that makes stable delivery of Matrikynes® peptides at 3% within a high-active cream emulsion possible. Emulsifier performance and peptide delivery are directly connected.
