Hey there - those are same natural preservatives 

VERSATIL® TBG MB INCI: Triethyl Citrate, Glyceryl Caprylate, Benzoic Acid 

Solubility: Insoluble in water pH Stability: 4.0-6.0 Usage Level: 1.0-1.5% Versatil® TBG MB is insoluble in water and requires a solubiliser to incorporate it into water-based products and emulsions. Versatil® TBG MB is effective against Gram-positive and Gram-negative bacteria and yeast, however it needs to be boosted in its action against mould in order to cover the full spectrum.

EUXYL® K903 INCI: Benzyl Alcohol, Benzoic Acid, Dehydroacetic Acid, Tocopherol

Solubility: Limited water solubility pH Stability: 5.0-5.5 Usage Level: 0.4-1.2% Euxyl® K 903 is a liquid preservative for personal care products, with strong, broad-spectrum efficacy against bacteria, yeasts and moulds. This is a very effective preservative at low concentrations for all rinse-off and leave-on products. Since the preservative has lipophilic components, it is not completely water soluble; at 20°C, 100g of water will dissolve 1.2g of Euxyl® K 903. For water-based products, a solubiliser will be required to incorporate it into water, however it is best used in products that contain an oil phase.

LEUCIDAL® SF MAX INCI: Lactobacillus Ferment 

Solubility: Water soluble pH Stability: 3.0-8.0 Usage Level: 2.0-4.0% Leucidal® Liquid SF MAX is a probiotic-based ingredient created by the fermentation of Lactobacillus in a defined growth medium. Leucidal® SF MAX provides broad spectrum antimicrobial protection. Leucidal® SF Max can be used in a wide range of cosmetic products, however to ensure optimum results it is recommended that it is incorporated into formulations at a pH between 3 and 8, during the cooling phase of the process at temperatures lower than 70°C.

SPECTRASTAT™ G2 NATURAL MB INCI: Caprylhydroxamic Acid, Glyceryl Caprylate, Glycerin 

Solubility: Oil Soluble pH Stability: 4.0-8.0 Usage Level: 1.0-1.5% Spectrastat™ G2 Natural MB is a 100% natural broad spectrum alternative preservation system made from a blend of multi-functional ingredients. It is oil soluble and may be used in emulsion, anhydrous, and surfactant systems.These include creams, lotions, shower gels and make-up. It may be added in the final stage of formulation.

OPTIPHEN™ BSB-N/ROKONSAL™BSB-N INCI: Benzyl Alcohol, Glycerin, Benzoic Acid, Sorbic Acid 

Solubility: Miscible in water pH Stability: 2.0-5.4 Usage Level: 0.3-1.0% Optiphen™ BSB-N/Rokonsal™BSB-N is a nature-identical preservative for cosmetics. It is a broad spectrum liquid preservative that is effective against Gram-negative bacteria, yeast and mould. Optiphen™ BSB-N/Rokonsal™BSB-N was specifically designed for formulations with a pH of 2.0- 5.4 due to the presence of organic acids in its system. The lower the pH of the formulation, the better the efficacy of the preservative. It is ECOCERT, COSMOS, NATRUE and BDIH-compliant. Optiphen™ BSB-N/Rokonsal™BSB-N can be used in both O/W and W/O emulsions.

OPTIPHEN™ BSB-W INCI: Benzyl Alcohol, Aqua, Sodium Benzoate, Potassium Sorbate

Solubility: Water soluble pH Stability: up to 5.4 Usage Level: 0.3-1.0% Optiphen™ BSB-W is a nature identical preservative for cosmetics, it is broad spectrum protecting against Gram-positive and Gram-negative bacteria, yeast and mould. It can be selected for natural or organic personal care products. This preservative supports a variety of natural personal care products. It is recommended for use in products with a pH of 5.4 or below. The lower the pH of the formulation, the better the efficacy of the preservative. It is ECOCERT, COSMOS, NATRUE and BDIH-compliant.
