Topically, it has been used in lotions as a soothing agent, oil-in-water emulsifier, and as astringent. Acacia Senegal gum is used externally to cover inflamed surfaces like bums or nodular leprosy.
Stabilizer
Stabilizer is a general term that describes ingredients with several functions that stabilize the properties of personal care products and prevent unwanted changes in color, odor, constituency, and texture. The use of antioxidants, UV absorbers, and chelating agents to protect cosmetic and household products has become a commonly accepted procedure.
In general, these stabilizers or mixtures thereof have to allow substrates to retain a pleasant appearance (e.g., in terms of color and odor), ensure the stability of emulsions, and maintain the rheological properties (e.g., viscosity) of the product. Moreover, the integrity and efficacy of labile active ingredients such as fragrances, vitamins, and natural extracts have to be maintained.
The ideal stabilizer should be stable and effective over a wide pH range, and any reaction byproducts should be colorless and odorless. Other evident and essential requirements are that it should be non-toxic and compatible with all ingredients in the products and their packages.
Because of this and the need for product differentiation in this competitive market, the cosmetics and toiletries industry needs to develop new and improved stabilizers, these new chemistries reduce the drawbacks associated with current "state-of-the-art" products and allow formulators to produce products with more effect-driven requirements.Examples of these include antioxidants with a lower tendency to discolor, biodegradable chelates, and ultraviolet absorbers that protect over a broader range (UVA and UVB). All these materials allow new tools to expand various key properties of products, such as shelf life, color selection, and environmentally friendly formulations. The use of these new chemistries offers superior protection for products being sold in a highly competitive marketplace.
BHT (Butylated Hydroxytoluene) is an antioxidant, white crystalline powder that will delay the rancidity of oils and fats in food and personal care applications.
Carrageenans are anhydrogalactose sulfate polymers (both gelling and non-gelling types) obtained from red seaweeds, including Eucheuma and Chondrus species.
Carrageenan is a protein-reactive gum that stabilizes protein-containing cosmetic formulations.
Magnesium Aluminum Silicate (MAS) is a white, highly purified mineral derived from smectite clays. It serves as stabilizing, suspending, and emulsifying agent for cosmetic formulations.
Pentaerythrityl Tetra-Di-T-Butyl Hydroxyhydrocinnamate is a structurally modified BHT. This highly efficient phenolic antioxidant does not exhibit the drawbacks associated with BHT (high volatility and photo-oxidative yellowing) and is helpful for product protection and stabilization.
Polyquaternium-39 is an amphoteric terpolymer, a conditioning polymer that is compatible with anionic and amphoteric surfactants. It is a clear, colorless liquid with a mild aldehydic odor especially useful in natural soap-based formulations. It has a wide pH stability range of 3-12.
Stearamidopropyl Dimethylamine is a multifunctional ingredient, a hair-conditioning agent, thickener, and emollient that appears as white to yellowish flakes.
Sunflower Seed Oil Sorbitol Esters is a co-emulsifier corresponding to the cosmetic industry's "Green" trend. Being based on vegetable, renewable, and GMO-free sources and free from EO and PEG-containing substances, it has been approved by EcoCert.
