This work developed a mild cleansing composition containing supercritical CO2 extract of strawberry seeds (SC-CO2 strawberry seed oil) as a moisturizing and softening agent for the skin. Experiments showed that the oil concentration in this formulation affected the stability of the product. Only the formulation containing 0.5-2% of the extract showed high stability.
Washing formulation composition and preparation
· Sodium cocoamphoacetate and disodium lauryl sulfosuccinate were included as gentle surfactants in this new cleansing formula. A small amount of sodium lauryl sulfate served as the primary detergent, while cocamide DEA and cocamidopropyl betaine acted as secondary surfactants. SC-CO2 strawberry seed oil was incorporated for its moisturizing and active properties. The components were added in a specific order to ensure a uniform product: first, the oil was blended with glycerin and surfactants, followed by gradual addition of water.
· Stability tests indicated that oil concentration significantly affected the product's stability; only samples with 2% or less oil (C 0% St, C 0.5% St, C 1% St, C 2% St) remained stable. These formulations were all homogeneous, clear, colorless, pleasant-smelling liquids with no signs of instability. In contrast, samples containing more than 2% oil developed a visible layer on the surface one week after preparation.
What is Sodium Cocoamphoacetate and what are its main benefits?
Sodium Cocoamphoacetate is an amber liquid derived from coconut. It functions as a mild surfactant with excellent foaming properties, making it a popular ingredient in both skin and hair care products. Its dual-charged amphoteric structure helps it bind with both oil and water, aiding in the effective cleansing and conditioning of the skin and hair. Additionally, with its fruity scent and non-irritating properties, it is suitable for sensitive skin and products intended for children and babies.
How does Sodium Cocoamphoacetate function in skin care products?
In skin care formulations, Sodium Cocoamphoacetate acts as a surfactant, foam booster, and conditioning agent. It helps other ingredients blend well and facilitates the removal of sebum and impurities from the skin. Its ability to stabilize foam enhances the efficacy of products like shaving creams, soaps, and cleansers, providing a luxurious texture and gentle cleaning experience.
Why is Sodium Cocoamphoacetate preferred in hair care formulations?
Sodium Cocoamphoacetate is prized in hair care products such as shampoos and conditioners due to its ability to cleanse and enhance the appearance of hair. It contributes to increased hair body, suppleness, and sheen, particularly for hair that has undergone physical or chemical damage. Its mild nature makes it suitable for frequent use without causing irritation or sensitivity.
Is Sodium Cocoamphoacetate safe for use in personal care products?
Yes, Sodium Cocoamphoacetate is considered a low-hazard ingredient according to the Cosmetics Database and is approved by the Cosmetic Ingredient Review (CIR) with certain concentration limits. Studies indicate that it is non-mutagenic, non-toxic in acute oral toxicity assessments, and does not act as an irritant or sensitizer at concentrations up to 10%.
What role does Sodium Cocoamphoacetate play in product formulations?
Sodium Cocoamphoacetate plays a multi-faceted role in product formulations, primarily serving as a cleansing agent and surfactant. It enhances the aesthetic quality of foams, improves the texture and spreadability of creams and gels, and offers mild yet effective cleansing, making it an indispensable ingredient in many personal care products.
How is Sodium Cocoamphoacetate produced?
The production of Sodium Cocoamphoacetate involves reacting coconut acid with aminoethylethanolamine to create an imidazoline. This is then reacted with monochloracetic acid or monochloropropionic acid in the presence of sodium hydroxide, leading to the formation of mono- or dicarboxylated products. These products are amber liquids containing 40% to 50% solids, with sodium chloride added to increase viscosity.
