Can SLES in Cosmetic Formulations Improve Moisturizing Effects

16-04-2026

Zhengzhou Mahaco Industrial Co.,Ltd (MAHACO) is a reputable supplier of SLES (sodium lauryl ether sulfate) for cosmetic formulations, including shampoos, body washes, hand washes, and more. The article explores whether SLES can improve the moisturizing effects in personal care products. SLES is predominantly a surfactant known for its effective cleansing and foaming abilities, but it can sometimes strip natural oils, potentially leading to moisture loss. However, MAHACO's research and formulation expertise demonstrate that SLES, when used at appropriate concentrations and combined with moisturizing agents such as glycerin, panthenol, aloe vera, and hyaluronic acid, can be a component of moisturizing cosmetics and skin care products.

By carefully selecting the SLES concentration and incorporating emollients, humectants, and co-surfactants, MAHACO manages to optimize product performance while minimizing potential dryness and irritation. The company also emphasizes sustainable sourcing and biodegradable SLES options. Their strategies include using SLES in synergy with gentle surfactants and innovative ingredients, leading to consumer products that deliver both effective cleansing and lasting hydration. Brands and manufacturers seeking technical support or customized solutions can rely on MAHACO’s expertise to develop high-quality, moisturizing cosmetic formulations with SLES.




Can SLES in Cosmetic Formulations Improve Moisturizing Effects? Insights from Zhengzhou Mahaco Industrial Co.,Ltd


SLES in cosmetic formulations—more formally known as Sodium Lauryl Ether Sulfate—is a prevalent ingredient in personal care products worldwide. As a leading supplier and manufacturer in the cosmetics industry, Zhengzhou Mahaco Industrial Co.,Ltd (MAHACO) continuously explores the potential advantages and limitations of SLES, especially regarding its impact on skin hydration and overall product performance.


Understanding SLES: Its Role in Cosmetic Formulations

SLES for shampoo, SLES for liquid soap, and SLES for facial cleansers are among the most sought-after applications. SLES acts primarily as a surfactant, offering excellent foaming and cleaning properties. MAHACO SLES 70% and MAHACO SLES 28% are two popular concentrations used in cosmetic and personal care products. But the key question remains: can SLES improve the moisturizing effects of cosmetic formulations, or does it have a drying effect?


The Science of SLES and Moisturization

Moisturization in skin and hair care relies on ingredients that can either attract, retain, or prevent the loss of water. SLES, as an anionic surfactant, is effective for removing oils and impurities. However, its action on the lipid layer of the skin and hair can sometimes lead to concerns about moisture loss. Leading SLES suppliers in China, like MAHACO, address these challenges by optimizing formulation strategies and combining SLES with moisturizing agents.

How SLES Interacts with Skin and Hair

  • SLES surfactant for cosmetics: Cleanses by emulsifying oils and lifting dirt.

  • Removal of natural oils can lead to increased transepidermal water loss (TEWL).

  • Proper formulation can mitigate potential dryness and maintain skin hydration.

  • Addition of humectants and emollients can counterbalance SLES’s cleansing power.

Through continuous R&D, MAHACO has developed innovative blends such as SLES with glycerin and SLES with aloe vera, targeting improved moisture retention for end-users.


Product Keywords: SLES Uses and Benefits in Cosmetic Products

  • SLES for emulsifiers

  • SLES for hand wash

  • SLES for body wash

  • SLES for hair care products

  • SLES surfactant for detergents

  • SLES for industrial cleaners

  • SLES for baby products

  • SLES for transparent shampoo

  • SLES for foaming agent

  • SLES for oral care

Integrating SLES with moisturizing agents has become a hallmark of MAHACO formulations, leveraging the ingredient’s cleaning power while controlling its impact on skin hydration.


MAHACO’s Approach to Enhancing Moisturizing Effects with SLES

At Zhengzhou Mahaco Industrial Co.,Ltd, formulation chemists research synergistic combinations that maximize the moisturizing effects of SLES in skin care. Strategies include:

  • Utilizing lower concentrations of SLES (e.g., SLES 28%) in sensitive formulations.

  • Blending SLES with natural oils, emollients, and humectants like glycerin, panthenol, and hyaluronic acid.

  • Using advanced encapsulation technology to reduce SLES’s direct contact with the skin’s lipid barrier.

  • Incorporating mild co-surfactants to optimize mildness and moisture retention.

Examples from MAHACO’s product line include moisturizing facial cleansers with SLES and moisturizing hand wash with SLES, which demonstrate measurable improvements in skin hydration after use, as confirmed by both instrumental testing and consumer feedback.

Key Considerations: SLES Dosage and Formulation

Formulation TypeSLES ConcentrationRecommended Moisturizing Additives
Shampoo5-15%Glycerin, Panthenol, Aloe Vera
Facial Cleanser2-7%Hyaluronic Acid, Allantoin, Natural Oils
Body Wash5-12%Shea Butter, Vitamin E, Plant Extracts

It is evident that SLES, when used at appropriate levels and combined with effective moisturizing agents, can be part of moisturizing cosmetic products.


Comparing SLES with Other Surfactants for Moisturizing Effects

SLES is often compared with other surfactants like SLS (Sodium Lauryl Sulfate) and amphoteric surfactants (e.g., cocamidopropyl betaine). MAHACO recommends SLES over SLS in cosmetic formulations due to its reduced irritancy and better skin compatibility, provided it’s formulated thoughtfully.

  • SLES vs. SLS: SLES generally causes less dryness and irritation.

  • SLES with betaine: Adding amphoteric surfactants can boost mildness and hydration.

For moisturizing baby shampoo with SLES, the lowest effective concentration is always paired with potent moisturizing complexes.


Innovative Formulation: The MAHACO Way

At MAHACO, product development is guided by consumer needs and scientific advancements. For clients looking to buy SLES in bulk for cosmetics, MAHACO provides not only the raw material but also formulation consultancy to ensure the best balance between cleansing, foaming, and moisturizing.

SLES for Sensitive Skin Products

  • Blending SLES with amino acid surfactants for ultra-mild cleansing.

  • Introducing plant extracts and ceramides to rebuild the skin barrier.

  • Using SLES in low-irritation formulas for facial cleansers and kids’ wash products.

These efforts have led to the creation of moisturizing creams with SLES and nourishing shower gels with SLES that offer rich, creamy foam without the trade-off of excessive dryness.


Global trends show that consumers are increasingly seeking products that offer both effective cleansing and enhanced moisturization. MAHACO partners with international brands to develop SLES-based personal care products that meet these demands. Recent studies have shown that using SLES in combination with humectants results in improved consumer satisfaction scores relating to skin feel and long-term hydration.
